AK4113
192kHz 24bit DIR with 6:1 Selector
GENERAL DESCRIPTION The AK4113 is a 24-bit stereo digital audio receiver that supports sampling rates up to 216kHz. The channel status bits decoder supports both consumer and professional modes. The AK4113 automatically detects non-PCM bit streams such as Dolby Digital, MPEG etc. When combined with the multi channel codec (AK4626 or AK4628), the two chips provide a system solution for Dolby Digital applications. Control of AK4113 is achieved though a P or pin strapping (parallel mode). It is packaged in a space-saving 30-pin VSOP. * Dolby Digital is a trademark of Dolby Laboratories.

OPERATION OVERVIEW Non-PCM (Dolby Digital, MPEG, etc) and DTS-CD Bitstream Detection
The AK4113 has a non-PCM bit stream auto-detection function, When the 32bit mode non-PCM preamble based on Dolby "Dolby Digital Data Stream in IEC 60958 Interface" is detected, the NPCM bit sets to "1". The 96-bit sync code consists of 0x0000, 0x0000, 0x0000, 0x0000, 0xF872 and 0x4E1F. Detection of this pattern will set the NPCM bit to "1". Once the NPCM bit is set to "1", it will remain "1" until 4096 frames pass through the chip without an additional sync pattern being detected. When those preambles are detected, the burst preambles Pc (burst information: Table 17) and Pd (length code: Table 18) that follow those sync codes are stored to registers. The AK4113 has also a DTS-CD bitstream auto-detection function. When the AK4113 detects DTS-CD bitstream, the DTSCD bit sets to "1". If the next sync code does not occur within 4096frames, the DTSCD bit sets to "0" until a non-PCM bitstream is detected again. The ORed value of NPCM and DTSCD bits are output to AUTO bit. The AK4113 detects the 14-bit sync word and the 16-bit sync word of a DTS-CD bitstream, the detection function can be set ON/OFF by DTS14 and DTS16 bits in serial control mode. In parallel control mode, logical OR value of the AUTO and AUDION bits are outputted to the INTI pin. The DTS-CD detects both the 14-bit sync word and the 16-bit sync word.
216kHz Clock Recovery
The integrated low jitter PLL has a wide lock range from 8kHz to 216kHz. The lock time depends on sampling frequency (fs) and FAST bit. (See Figure 12) FAST bit is useful at lower sampling frequency and is fixed to "0" in parallel control mode. In serial control mode, the AK4113 has a sampling frequency detection function (8kHz, 11.025kHz, 16kHz 22.05kHz, 32kHz, 44.1kHz, 48kHz, 64kHz, 88.2kHz, 96kHz, 176.4kHz and 192kHz) that uses either a clock comparison against the X'tal oscillator or the channel status information from the setting of XTL1-0 bits. In parallel control mode, the sampling frequency is detected by using the reference frequency, 24.576MHz. When the sampling frequency is more than 64kHz, FS96 pin goes to "H". When the sampling frequency is less than 54kHz, FS96 pin goes to "L". The PLL loses lock when the received sync interval is incorrect. FAST bit PLL Lock Time 0 Default (15 ms + 384/fs) 1 (15 ms + 1/fs) Figure 12. PLL Lock Time (fs: Sampling Frequency)

Clock Operation Mode
The CM0 and CM1 pins (or bits) select the clock source and the data source of SDTO. In Mode 2, the clock source is switched from PLL to X'tal when PLL goes unlock state. In Mode3, the clock source is fixed to X'tal, but PLL is also operating and the recovered data such as C bits can be monitored. For Mode2 and 3, it is recommended that the frequency of X'tal is different from the recovered frequency from PLL.

Master Clock
The AK4113 has two clock outputs, MCKO1 and MCKO2. MCKO2 has two modes. These modes can be selected by the XMCK bit. 1) When XMCK bit = "0" and BCU bit = "0" This mode is compatibile AK4112B and AK4114. These clocks are derived from either the recovered clock or the X'tal oscillator. The frequencies of the master clock outputs (MCKO1 and MCKO2) are set by OCKS0 and OCKS1 as shown in Table 2. The 512fs clock will not operate when the sampling frequency is 96kHz or 192kHz. The 256fs clock will not operate when the sampling frequency is 192kHz.

The output frequency can be set by the DIV bit. MCKO1 outputs a clock that is selected by the CM1-0 bits and OCKS1-0 bits.

Sampling Frequency and Pre-emphasis Detection
The AK4113 has two methods for detecting the sampling frequency. 1. Clock comparison between the recovered clock and X'tal oscillator 2. Sampling frequency information on channel status The method is selected by the XTL1-0 bits. The detected frequency is available on the FS3-0 bits. When XTL1-0 bits = "11", the sampling frequency is detected by the channel status sampling frequency information. The detected frequency is available on the FS3-0 bits. In parallel control mode, XTL1-0 bits are fixed to "10". XTL1 bit 0 0 1 1 XTL0 bit X'tal Frequency 0 11.2896MHz 1 12.288MHz 0 24.576MHz 1 (Use channel status) Table 4.

De-emphasis Filter Control
The AK4113 includes a digital de-emphasis filter (tc=50/15s). This is an IIR filter that corresponds to four sampling frequencies (32kHz, 44.1kHz and 48kHz). When DEAU bit="1", the de-emphasis filter is enabled automatically by the sampling frequency and pre-emphasis information in the channel status. The AK4113 is in this mode by default. In parallel control mode, the AK4113 is always placed in this mode and the status bits in channel 1 control the de-emphasis filter. In serial control mode, DEM1-0 bits control the de-emphasis filter when the DEAU is "0". The internal de-emphasis filter is bypassed and the recovered data is available without any change if the de-emphasis mode is OFF. When the PEM bit is "0", the internal de-emphasis filter is always bypassed.

The AK4113 has a power-down mode for all circuits using the PDN pin or it can be partially powerd-down with the PWN bit. The RSTN bit initializes the register and resets the internal timing. In parallel control mode, only control by the PDN pin is enabled. The AK4113 should be reset once by bringing PDN pin = "L" upon power-up. PDN Pin: All analog and digital circuits are placed in power-down and reset mode by bringing PDN pin = "L". All the registers are initialized, and clocks are stopped. Reading/Witting to the registers are disabled. RSTN Bit (Address 00H; D0): All the registers except PWN and RSTN bits are initialized by bringing RSTN bit = "0". The internal timings is also initialized. Writing to registers is not available except the PWN and RSTN bits. Reading from the registers is disabled. PWN Bit (Address 00H; D1): The clock recovery is initialized by bringing PWN bit = "0". In this case, the clocks are stopped. The registers are not initialized and the mode settings are maintained.

U-bit buffers
The AK4113 has a Q-subcode buffer for CD application. The AK4113 takes the Q-subcode into registers by the following method. 1. The sync word (S0,S1) is constructed of at least 16 "0"s. 2. The start bit is "1". 3. Those 7bits Q-W follows to the start bit. 4. The distance between two start bits are 8-16 bits. The QINT bit in the control register goes to "1" when the new Q-subcode differs from old one, and goes to "0" when the QINT bit is read.

Error Handing
The following nine events cause the INT0 and INT1 pins to show the status of the interrupt condition. When the PLL is OFF (Clock Operation Mode 1), INT0 and INT1 pins go to "L". 1. UNLCK : PLL unlock state detect "1" when the PLL loses lock. The AK4113 loses lock when the distance between two preamble is not correct or when those preambles are not correct. : Parity error or bi-phase coding error detection "1" when parity error or bi-phase coding error is detected, updated every sub-frame cycle. : Non-Linear PCM or DTS-CD Bit Stream detection The OR function of NPCM and DTSCD bits is available at the AUTO bit. : Validity flag detection "1" when validity flag is detected. Updated every sub-frame cycle. : Non-audio detection "1" when the "AUDION" bit in recovered channel status indicates "1". Updated every block cycle. : Sampling frequency or pre-emphasis information change detection When either FS3-0 bit or PEM bit is changed, it maintains "1" during 1 sub-frame. : U-bit Sync flag "1" when the Q-subcode differs from the old one. Updated every sync code cycle for Q-subcode. : Channel status sync flag "1" when received C bit differs from the old one. Updated every block cycle. : DAT Start ID detect "1" when the category code indicates "DAT" and "DAT Start ID" is detected. When DCNT bit is "1", it does not indicate "1" even if "DAT Start ID" is detected again within "3841 x LRCK". When "DAT Start ID" is detected again after "3840 x LRCK" passed, it indicates "1". When DCNT bit is "0", it indicates "1" every "DAT Start ID" detection.

2. Serial control mode In serial control mode, the INT1 and INT0 pins output an ORed signal based on the above nine interrupt events. When masked, the interrupt event does not affect the operation of the INT1-0 pins (the masks do not affect the registers in 07H and DAT bit). Once the INT0 pin goes to "H", it remains "H" for 1024/fs (this value can be changed with the EFH1-0 bits) after all events not masked by mask bits are cleared. INT1 pin immediately goes to "L" when those events are cleared. UNLCK, PAR, AUTO, AUDION and V bits in Address=07H indicate the interrupt status events above in real time. Once QINT, CINT and DAT bits goes to "1", it stays "1" until the register is read. When the AK4113 loses lock, the channel status bit, user bit, Pc and Pd are initialized. In this initial state, INT0 pin outputs the ORed signal between UNLCK and PAR bits. INT1 pin outputs the ORed signal between AUTO and AUDION bits.

Audio Serial Interface Format
The DIF0, DIF1 and DIF2 pins can select eight serial data formats as shown in Table 16. In all formats the serial data is MSB-first, 2's compliment format. The SDTO is clocked out on the falling edge of BICK and DAUX is latched on the rising edge of BICK. BICK outputs 64fs clock in Mode 0-5. Mode 6-7 are Slave Modes, and BICK is available up to 128fs at fs=48kHz. If the data word length is equal or less than 20-bits (Mode0-2), the LSBs in the sub-frame are truncated. In Mode 3-7, the last 4-LSBs are auxiliary data (see Figure 26). When the Parity Error, Bi-phase Error or Frame Length Error occurs in a sub-frame, the AK4113 continues to output the last normal sub-frame data from SDTO repeatedly until the error is removed. When the Unlock Error occurs, AK4113 outputs "0" from SDTO. If DAUX is used, the data is transformed and outputted from SDTO. DAUX is used in Clock Operation Mode 1, 3 and unlock state of Mode 2. The input data format to DAUX should be left justified except in Mode 5 and 7. In Mode 5 or 7, both the input data format of DAUX and output data format of SDTO are I2S. Mode 6 and 7 are Slave Modes that corresponds to the Master Mode of Mode 4 and 5. In Slave mode, LRCK and BICK should be synchronized with MCKO1/2.

Serial Control Interface
1. 4-wire serial control mode (I2C pin = "L") The internal registers may be either written or read by the 4-wire P interface pins: CSN, CCLK, CDTI & CDTO. The data on this interface consists of Chip address (2bits, C1-0 are fixed to "00"), Read/Write (1-bit), Register address (MSB first, 5-bits) and Control data (MSB first, 8-bits). Address and data is clocked in on the rising edge of CCLK and data is clocked out on the falling edge. For write operations, data is latched after the 16th rising edge of CCLK, after a high-to-low transition of CSN. For read operations, the CDTO output goes high impedance after a low-to-high transition of CSN. The maximum speed of CCLK is 5MHz. PDN pin = "L" resets the registers to their default values.

ASAHI KASEI 2. I2C bus control mode (I2C pin = "H") The AK4113 supports a fast-mode I2C-bus system (max : 400kHz). 2-1. Data transfer
[AK4113]
All commands are preceded by a START condition. After the START condition, a slave address is sent. After the AK4113 recognizes the START condition, the device interfaced to the bus waits for the slave address to be transmitted over the SDA line. If the transmitted slave address matches an address for one of the devices, the designated slave device pulls the SDA line to LOW (ACKNOWLEDGE). The data transfer is always terminated by a STOP condition generated by the master device. 2-1-1. Data validity The data on the SDA line must be stable during the HIGH period of the clock. The HIGH or LOW state of the data line can only change when the clock signal on the SCL line is LOW except for the START and the STOP condition.

ASAHI KASEI 2-1-3. ACKNOWLEDGE
[AK4113]
ACKNOWLEDGE is a software convention used to indicate successful data transfers. The transmitting device will release the SDA line (HIGH) after transmitting eight bits. The receiver must pull down the SDA line during the acknowledge clock pulse so that that it remains stable "L" during "H" period of this clock pulse. The AK4113 will generates an acknowledge after each byte has been received. In the read mode, the slave, the AK4113 will transmit eight bits of data, release the SDA line and monitor the line for an acknowledge. If an acknowledge is detected and no STOP condition is generated by the master, the slave will continue to transmit data. If an acknowledge is not detected, the slave will terminate further data transmissions and await the STOP condition.

The most significant five bits of the slave address are fixed as "00100". The next two bits are CAD1 and CAD0 (device address bits). These two bits identify the specific device on the bus. The hard-wired input pins (CAD1 pin and CAD0 pin) set them. The eighth bit (LSB) of the first byte (R/W bit) defines whether a write or read condition is requested by the master. A "1" indicates that the read operation is to be executed. A "0" indicates that the write operation is to be executed.

ASAHI KASEI 2-2. WRITE Operations
[AK4113]
Set R/W bit = "0" for the WRITE operation of AK4113. After receipt the start condition and the first byte, the AK4113 generates an acknowledge, and awaits the second byte (register address). The second byte consists of the address for control registers of AK4113. The format is MSB first, and those most significant 3-bits are "Don't care".

Figure 37. Byte structure after the second byte The AK4113 is capable of more than one byte write operation by one sequence. After receipt of the third byte, the AK4113 generates an acknowledge, and awaits the next data again. The master can transmit more than one words instead of terminating the write cycle after the first data word is transferred. After the receipt of each data, the internal 5bits address counter is incremented by one, and the next data is taken into next address automatically. If the address exceed 1CH prior to generating the stop condition, the address counter will "roll over" to 00H and the previous data will be overwritten.

ASAHI KASEI 2-3. READ Operations
[AK4113]
Set R/W bit = "1" for the READ operation of AK4113. After transmission of a data, the master can read next address's data by generating the acknowledge instead of terminating the write cycle after the receipt the first data word. After the receipt of each data, the internal 5bits address counter is incremented by one, and the next data is taken into next address automatically. If the address exceed 1CH prior to generating the stop condition, the address counter will "roll over" to 00H and the previous data will be overwritten. The AK4113 supports two basic read operations: CURRENT ADDRESS READ and RANDOM READ. 2-3-1. CURRENT ADDRESS READ The AK4113 contains an internal address counter that maintains the address of the last word accessed, incremented by one. Therefore, if the last access (either a read or write) was to address n, the next CURRENT READ operation would access data from the address n+1. After receipt of the slave address with R/W bit set to "1", the AK4113 generates an acknowledge, transmits 1byte data which address is set by the internal address counter and increments the internal address counter by 1. If the master does not generate an acknowledge to the data but generate the stop condition, the AK4113 discontinues transmission

Figure 39. CURRENT ADDRESS READ 2-3-2. RANDOM READ Random read operation allows the master to access any memory location at random. Prior to issuing the slave address with the R/W bit set to "1", the master must first perform a "dummy" write operation. The master issues the start condition, slave address(R/W bit ="0") and then the register address to read. After the register address's acknowledge, the master immediately reissues the start condition and the slave address with the R/W bit set to "1". Then the AK4113 generates an acknowledge, 1byte data and increments the internal address counter by 1. If the master does not generate an acknowledge to the data but generate the stop condition, the AK4113 discontinues transmission.
