D- 60
STEREO 60W-100W DIGITAL AUDIO POWER AMPLIFIER CONTROLLER Outline
YDA136 (D-60) is a high efficient and high output digital audio power amplifier controller IC. By combining a general purpose PowerMOSFET (hereafter called PowerMOSFET) which is connected with YDA136 and BTL, it is able to compose a high efficient audio power amplifier such as 60Wx2ch (Supplied voltage=32V, RL=6) and 100Wx2ch (Supplied voltage=40V, RL=6). YDA136 has 24bit 192kHz (max) DAC and 6 to -73dB1dB Step of electron volumes in addition to a digital amplifier controller, and supports a digital audio signal input. Furthermore, it also supports an analog audio signal input with DAC bypasses. YDA136 realizes a high-standing audio characteristic that is lower noise and distortion rate by performing an analog feedback from PowerMOSFET output, and by using Yamaha's unique modulation method. YDA136 also equips a function (Over current detection function) which protects a circuit from a short of speaker output terminal (after the LC filter) and a function (Supplied voltage detection function) which prevents a malfunction by detecting a power supply falling. Moreover, it has a function (Clock stop detection function) to protect a circuit by detecting a stop termination of PWM carrier clock and a function (High-temperature detection function) to protect a circuit by detecting the unusual high-temperature condition of it-self. At last, by making three YDA136 to daisy-chain connection, the audio system of 6ch is easily realizable.

Rch over current detection terminal "OCPLR and OCPHR" can not be operated in Monophonic mode. In the over current detection mode, the mode is continued even if it goes out of the over current condition. The over current detection mode is canceled by protect reset mode. 6) All registers are initialized when VDD2 voltage (VDD-VSS) becomes below VVD in the low voltage detection modes. 7) When YDA136 it-self heats higher than the unusual temperature (Tmax), it will become a high temperature detection mode. Digital Audio Signal Input Mode / Analog Audio Signal Input Mode YDA136 can input both Digital Audio Signal and Analog Audio Signal. In case of input for the digital audio signal, be sure to connect DAC output terminal (AOL, AOR) and electron volume input terminal (AIL, AIR) through capacitor for DC cut. In addition, in case of input for the analog audio signal; be sure to connect an analog audio signal to electron volume input terminal (AIL,AIR) through a capacitor for DC cut. At this time, the output of DAC can be made into High-Z by setting the DAC input format of a control register as MODE8. 1) 2) 3) 4) 5)

MPU Interface Function
By using the following three terminals "CSN, MCLK, and VDI", data is written into Volume register and Control register. In case of writing data in the Control register, be sure to set mute to Volume register in advance. After a write of Control register or after the given time (TZERO, TCF, TOSFN, TMOD, and TFS), be sure to cancel mute condition. Input Format Please input the data of each 14-bit register into a VDI terminal in MSB first following address bits. The data input from VDI terminal is taken into internal shift register at the rising edge of MCLK terminal when CSN terminal is "L." The data input into shift register is written into the register of the appointed address at the rising edge of CSN terminal. All the values of registers after a power up are set to "0." After a power supply starting, the MPU interface works after passing over a serial access prohibition time (TPUP). Be sure to perform a power supply staring first, and then perform a write of the data to a register after a serial access prohibition time (TPUP).

Here, A1 and D1 [13:0] indicates a register to update and data. In addition, A0 and D0 [13:0] indicates a data input into VDI terminal before 16-clock. Daisy-chain Multiple Daisy-chain connections for multi-channel system are available in YDA136. For example, 6ch system can be realized by connecting three YDA136 with Daisy-chain connection. By connecting a VDO terminal of first YDA136 to VDI terminal of the second YDA136; and then, connecting a VDO output of second YDA136 to a VDI terminal of the third YDA136, it becomes available to control those three YDA136 simultaneously without a complex addressing. The data in which it overflowed from the internal 15-bit shift register among the data inputted into each VDI terminal of YDA136 is output from a VDO terminal synchronizing with falling edge of a MCLK terminal. By setting CSN terminal to "L" during the number of YDA136x15-clock which daisy-chain connection was made, an input data is taken into each shift register of YDA136. Then, writing is simultaneously performed to a volume register (control register) from the shift register of all YDA136 connected to the daisy-chain by setting the CSN terminal of YDA136 to "H."

Over Sampling Filter Be sure to set up the Over Sampling mode according to a sampling frequency (Fs) of audio signals to input. Over sampling filter mode can be set up by FS1 and FS0 in the control register. In addition, an over sampling filter can be bypassed by the setting of control register OSF. When Fs is 32kHz, 44.1kHz or 48kHz Sets up to the 4x mode. When Fs is 64kHz, 88.2kHz, or 96kHz Sets up to the 2x mode. When Fs is 176.4kHz or 192kHz Sets up to the 1x mode. When it is set as Auto mode, the above mentioned over sampling modes are set up by detecting a sampling frequency (Fs) of audio signal which was input.
Volume Function
YDA136 has the electronic volume which can be set up in the range from +6dB to -73dB by 1dB step. By inputting an analog signal from AIL (AIR) terminal, and attenuating with the set up volume value, this electronic volume outputs a differential analog signal from an OPL (OPR) terminal and OML (OMR) terminal. Non-inverted signal from OPL (OPR) terminal and inverted signal from OML (OMR) terminal is output. The maximum input level is 1Vrms and the maximum output level is 1Vrms. Be sure to set a volume value to a volume register through a MPU serial data interface. Moreover, in order to suppress the noise at the time of volume value change, a mode (Zero-cross mode) which changes a volume value when an output signal carries out a zero-cross, is provided as an option. Volume Register D [13:7] of a volume register shows the volume value of R channels, and D [6:0] shows the volume value of L channels. "1111111" and from "0101110" to "0000000" becomes mute among each volume value. At this time, a DAC output signal turns into a non-signal irrespective of an input. Zero-cross Mode This is the volume change mode, which reduces the noise generated at the time of change of the volume value of electronic volume. When this mode is selected, the volume value is changed under the following conditions. At the time of an audio signal carries out a Zero-cross After the volume change is set up After the volume value setting time (TZEROWAIT) When not selected, the volume is changed regardless of the input after the volume setting. By ZERO of a control register, Zero-cross mode can be set.

Digital Amplifier Function
YDA136 has a 2-channel differential analog signal input digital amplifier controller. This digital amplifier controller consists of High-Side and Low-Side PowerMOSFET drivers and a PWM circuit. By combining the two sets of Pch/Nch PowerMOSFET in each channel, a digital amplifier (60W to 100W) can be configured. To each PowerMOSFET driver, it is possible to set up an off-time individually, and it can be set as the optimal driver according to PowerMOSFET to be used. AM intermodulation can be performed with AM reception interference reduction function. Moreover, it can be optimized to the digital amplifier which has a lower distortion by adding a filter element to a PWM circuit. Gain Setup Method The gain of digital amplifier can be set up by external resistance (RE1 to RE4).
The gain of digital amplifier can be calculated with the following formula.
RE1 RE 2 + RE 2 RE 3 + RE1 RE 3 Av(dB ) = 20 log RE 2 (RE 4 + 400)
However, be sure to set RE4 as more than 10k according to the capability of a built-in operational amplifier. Characteristic Improvement by External Filter Element Connection Although it is possible to realize high performance digital amplifier by the PWM circuit, by adding resistor and a capacitor between DBPL(FBPR) and ITPL (ITPR), and between FBML (FBMR) and ITML (ITMR), it is possible to optimize a circuit further and to improve distortion rate.

Clock Input YDA136 operates synchronizing with 4.19MHz clock. Be sure to connect a 4.16MHz CERALOCK or to supply a clock to YDA136 from the outside. Be sure to always supply a clock except protection reset mode and hard mute mode. When using a CERALOCK, be sure to set MSSEL terminal to "L" and to set YDA136 to a master mode. In case of supplying a clock from the outside, be sure to set MSSL terminal to "H" and to set YDA136 to a slave mode. Master mode Be sure to set MSSEL terminal to "L." Connects CELALOCK to XI and XO terminal. Be sure to set the oscillation frequency to 4.19MHz. At this time, a master clock (4.19MHz) is output from a MCKIO terminal. Slave mode Be sure to set MSSEL terminal to "H." Be sure to input a master clock (4.19MHz) into a MCKIO terminal. At this time, be sure to set XI terminal to "L" and set XO terminal to open state. When making a multi channel amplifier by using multiple YDA136, a system with little interference between channels can be constituted by using one YDA136 in master mode, and using the remainder in slave mode as shown in the following figure.
AM Reception Interference Reduction Function YDA136 outputs the pulse made by modulating the career clock, which is made by dividing the input master clock. In order to reduce cross talk caused by the coincidence between harmonics of the output pulse and AM radio frequency, YDA136 has the changing (frequency hopping) function of two carrier clock frequencies. A carrier clock frequency can be chosen by the control register CF. Off-time Setup Function A setup of an off-time is individually possible for YDA136 to the High-Side driver and Low-Side driver of Lch and each Rch. Off-time adjustment of the Low-Side driver of Lch and each Rch is possible by the capacitor that is connected to a DLYLL terminal and a DLYLR terminal. Moreover, off-time adjustment of the High-Side driver of Lch and each Rch is possible by the capacitor connected to a DLYHL terminal and a DLYHR terminal. Relation between capacitance value of the capacitor and the relation of an off-time is shown in the figure. (Under characteristic adjustment)

PowerMOSFET Drive Function Since it is BTL connection digital amplifier, external connection of two sets per channel of Pch and Nch PowerMOSFET is made. A High-Side driver output is connected to Pch PowerMOSFET, and a Low-Side driver output is connected to Nch PowerMOSFET as shown below. Non-inverted side Pch PowerMOSFET Be sure to connect to OPPLU and OPPLD (OPPRU,OPPRD). (High-Side Driver Output) Non-inverted side Nch PowerMOSFET Be sure to connect to ONPLU and ONPLD (ONPRU,ONPRD).

Protect Function
Over Current Detection Function YDA136 has a function to perform an over current protection by detecting a voltage drop of the current detection resistor connected to the source side of PowerMOSFET. When the voltage of an over-current detection terminal fulfills the following conditions, it judges that it is in an over-current condition, and becomes over-current detection mode, and then a circuit is protected.
Voltage to be monitored Low-Side over-current detection terminal (OCPLL, OCPLR Voltage High-Side over-current detection terminalOCPHL, OCPHR Voltage and VBB Potential difference Over-current detection mode threshold < VOC2 > VOC1
In the example of peripheral circuit connection, the following four over-current conditions are detected, and then it becomes an over-current detection mode. A condition in which signals after LC filter and VSS power supply is shorted. A condition in which signals after LC filter of non-inverted side and signals after LC filter of inverted side is shorted. A condition in which one side of a speaker was connected to LC filter, and another side of a speaker is shorted to the VSS power supply. In over-current detection mode, PROTN terminal is set to "L", simultaneously it turns off all PowerMOSFET (hard mute) and protects a circuit. After it is made to over-current detection mode, even if an over-current condition is canceled, it is not canceled but is held as it is. Over-current detection mode can be canceled by intercepting a power supply or setting a PRSTN terminal to "L" at once. Power Detection Function YDA136 monitors the following three kinds voltage. When which voltage is less than regular voltage, it becomes low voltage detection mode. Voltage to be monitored IBB Terminal Voltage(It is proportional to the voltage between VBB and VSS) VDD1 (Voltage between VBB and VBS) VDD2 (Voltage between VDD and VSS) Constant Voltage Detection Mode Threshold VIB2 VVB2 VVD2
Here, since the IBB terminal has input the signal which divided VBB voltage, the IBB terminal will act as the monitor of the VBB voltage. Hard mute is operated in low voltage detection mode. Among these, all registers are reset when VDD2 voltage is less than threshold voltage (VVD2). Then, when three kinds of power supply voltage rises and a low voltage detection mode threshold is exceeded altogether, the low voltage detection mode is canceled and a hard mute is also canceled after starting standby time (TWAIT). Starting Standby Time Setup Starting standby time (TWAIT) can be set up by connecting a capacitor to the DET terminal of YDA136. Be sure to set up to usually be set to TWAIT>=600msec for internal initialization of YDA136. The value of starting standby time (TWAIT) and capacity (CDET) of and the capacitor linked to a DET terminal serves as the following relations. TWAIT = (k)xCDET(F) In the case of the capacity value (10F) of the capacitor in the example of peripheral circuit connection, TWAIT is set to 600msec.

YDA136
Clock Stop Detection Function YDA136 becomes clock stop detection mode, when a career clock frequency exceeds a maximum (FC1) of operation or it is less than a minimum (FC1). Hard mute is carried out in clock stop detection mode. If a career clock frequency enters within normal limits, clock stop detection mode will be canceled and hard mute will be canceled. High Temperature Detection Function YDA136 is acting as the internal monitor of the temperature of YDA136 self, and when it becomes an unusual temperature exceeding Tjmax, it serves as high temperature detection mode. In high temperature detection mode, a PROTN terminal is set to "L" at the same time it carries out hard mute. Then, a PROTN terminal is set to "H" at the same time it cancels high temperature detection mode and cancels hard mute, when temperature falls and it becomes a normal range. Self-recovery function By connecting a PROTN terminal and a PRSTN terminal, when a PROTN terminal is set to "L" by over-current detection and high temperature detection, it can be set as fixed time protection reset mode, and hard mute release (automatic return) can be carried out after starting standby time (TWAIT).

YDA136
Control Function
Hard Mute Function YDA136 serves as hard mute mode, when a MUTEN terminal is "L." In hard mute mode, they are all PowerMOSFETs. It turns off (hard mute). Hard mute will be canceled if a MUTEN terminal is set to "H." Rewriting of all registers is possible for during a hard mute mode period. Protect Reset Function YDA136 serves as protection reset mode, when a PRSTN terminal is "L." A PROTN terminal is set to "H" in protection reset mode. Hard mute is carried out simultaneously, the circuit which operates inside IC is minimized, and consumption current is reduced. After canceling protection reset mode, using a PRSTN terminal as "H", after starting standby time (TWAIT), hard mute is canceled and a start of operation is carried out. Rewriting of all registers is possible for during a hard mute mode period. Moreover, a register is by protection reset mode. is not carried out. Monophonic Function YDA136 serves as monophonic mode, when a MONO terminal is "H." In monophonic mode, only Lch outputs an audio signal, and all the circuits related to Rch is stopped. Moreover, it becomes stereo mode when a MONO terminal is "L." In monophonic mode, the over-current detection function by the OCPLR terminal and the PCPHR terminal does not operate. Please perform the change in monophonic mode and stereo mode at the time of interception of a power supply. The change in the monophonic mode by the MONO terminal at the time of power supply impression and stereo mode is forbidden.
Typical Voltage
Since a VREFL terminal and a VREFR terminal output 1/2*VDD2 voltage respectively, be sure to connect and stabilize a capacitor.
Initialization / Power-down
System Initialization All registers are initialized when VDD2 voltage (VDD-VSS) becomes less than VVD in low voltage detection modes. The initial value of each register is "0." Power-down At the time of power interception, be sure to intercept a power after set it as a hard mute mode.
