s FUNCTIONAL DESCRIPTION
1. Register Settings The MB86434 IC chip controls all electronic volume, switching, tone generator circuits and power-down control circuits by means of the SRD, STB and SRC data input signals. The MB86434 uses a 9-bit serial data format consisting of a 4-bit address followed by 5 data bits. Data is picked up at the rise of the SRC signal, and latched by the STB L-level signal. The 9-bits of serial data preceding the STB signal are considered valid. These register settings are not reset at power-down. They can be reset when data is initialized by an XPRST L-level signal.

(5) Tone Generator Circuit * Tone Frequency Control Registers The tone generator uses a clock signal obtained by subdividing the TCLK clock signal input by 1/1, 1/2 or 1/4 according to the data bit in address 1110. Table 3 Address 1110 D4 0 0 1 1 D3 0 1 0 1 Tone Clock Frequency Register Control Tone generator clock signal (fIN) TCLK input clock signal TCLK input clock signal subdivided by 1/2 TCLK input clock signal subdivided by 1/4 Prohibited
Frequency settings available through the tone frequency control register are determined by the following formula. Frequency setting f = fIN/(12*(1+n)), n = 1, 2, 3, ..., 255. (where fIN: tone generator clock signal frequency). Therefore the available frequency setting range when fIN = 512 kHz is between fmin = 167 Hz and fmax = 21333 Hz. Frequency settings corresponding to each DTMF rated reference frequency are shown in the following table.

Also, by connecting a capacitor between the TENV pin and the ground, it is possible to generate an envelope for the tone waveform. Set address 0111 data bit D2 to 1 to generate. If an envelope is generated, silencing must be applied by an L-level signal from the TONC pin. The type of envelope that can be generated can be calculated approximately from the following formula.
Time t required for V0/V1 = 2.7 (in ms) = 15 * C (in F) V0 TENV C TONEO T V1

* LED Output Controls Output from the LED output pins can be controlled by the TONC signal and the address 1110 data bit D2. When the TONC signal is H-level, and the address 1110 data bit D2 value is L-level, the output level will be high. Output levels are CMOS levels.

(6) Codec * Input/output Both the -law and A-law coding/decoding conversion processes used by the MB86434 codec are compatible with CCITT Recommendation G.711. In addition, linear coding in the form of 14-bit two's complement code can be output starting with MSB values.

* The codec SYNC pin The codec block requires the input of an 8 kHz sampling clock signal at the SYNC pin, as well as a data transfer clock at the CLK pin. In order to conserve power consumption, whenever the SYNC pin or CLK pin signal is inactive, the system goes into SYNC power-down mode and stops code conversion. Also, if either the SYNC or CLK pins encounters jitter of 5 s or greater, the system may go into power-down mode.Table shows the status of output pins in SYNC power-down mode.

2. Analog Input Analog input signals in the MB86434 include the two microphone inputs and the general-purpose analog switch. (1) Microphone Amps The microphone amps take the incoming signal from the microphones and amplify it to any desired level of gain. The microphone lines are low-noise types for use with piezoelectric-ceramic or capacitor microphones, and are capable of a wide range of amplification. All microphones and amps must be coupled with capacitors to prevent amplification of offset signals.

3. Analog Output The MB86434 has a total of four analog output circuits, including the three speaker drive circuits (receiver, earphone and tone) and the accessory output. (1) Speaker Drive Amp The speaker drive amps include two circuits (receiver and tone) with BTL output and one system (earphone) with single output. Because the speaker amp requires relatively high levels of power, it is connected to speaker selection switches (sw6-sw9) for power-down mode selection. Two systems (receiver and earphone) have fixed gain levels, while the other system (tone) allows gain adjustment by means of external resistors. In addition, the tone speaker amp is able to use the 200 mW large-current power circuit Table Parameter Output type Load resistance *1 Load resistance *2 Load capacity *2 Final stage gain Maximum output power *1: *2: Speaker Drive Amp Output Standards Earphone speaker amp (JEAR) Single 32 (typ) 2.8 k (typ) 70 nF 0.0 dB/-6.0 dB (JEAR) 5 mW (min) Tone speaker amps (TONE, XTONE) BTL 32 (typ) 2.8 kW (typ) 70 nF -5 to 20 dB (between TONE-XTONE) 200 mW (min)

(2) Accessory Output The accessory output (RAUD pin) can carry either digital or analog output signals, and is controlled by address 0101 data bit D4 (SW 8), and address 0111 data bit D1 (SW 12). When both SW 8 and SW 12 are in off position, the accessory outputline is in H-Z (high impedance) state. Caution: never place both SW 8 and SW 12 in on position at the same time. This may cause the MB86434 to function improperly. * SW12 in On Position

4. Receiver Connections It is possible to add tones and adjust sidetones by using amp 1,2 and 3 and the electronic volume control. When using amp 3, however, it is necessary to include HPF to avoid interference from the speaker amp DC. * Tone and Sidetone Addition by Inclusion of Secondary LPF and Primary HPF.

5. Power Saving Modes (1) Mode Selection The MB86434 power saving modes can be controlled by using the external control signal lines (3 lines). It is also possible to apply power saving modes to the speaker amps with high power consumption levels by writing changes to register settings. Whenever the MB86434 changes directly from a power-down mode to normal operating mode, there is a possibility that speaker tones may be produced. The recommended sequence of coding changes to go into normal mode is (VREF mode) (Tone mode) (Normal mode). Power Saving Modes

Codec in [Normal] mode operates with SYNC = 8 kHz, CLK = 2048 kHz. * When RAUD is operating, address 0111 data bit D1 value should be "0" (SW12 off). * In tone mode, address 0111 data bit D3 should be "0" (SW2 on), and address 0111 data bit D4 should be "0" (SW14 off). * When the SYNC and CLK pin signals are fixed at either L-level or H-level, part of the codec unit will go into power-down mode. At this time the PTBO signal will be SGC level, BTPO will be H-Z, and VRH output will be approximately 4.0 V.
