Part Number: PCM6340-Q1 PCM6340 for slave, DSP AK7739 for master
AK7739 produces 12.288MHz BICK, 48KHz FSYNC (TDM8, 32bits)
Problem description:
After normal power on, pcm6340 reads the 0x15 register display and cannot detect valid FS-RATE and FS-RATIO…
Part Number: PCM6340-Q1 Related background
1. SOC enables i2c to be connected to control PCM6340
2. There is also another Tuner core hanging on the same i2c circuit
Problem phenomenon
1. After multiple boards are powered on normally, the SOC can configure…
Hi, Sanjay,
If disconnecting these resistors, below fault is still reported when MIC is in working.
Questions:
1. The design target: ADC output 2Vrms is full-scale, but put resistor divider to ensure voltage not exceed. Will the to-GND resistor impact…
Part Number: PCM6340-Q1 When we used PCM6340QRTVRQ1, we faced the below problem in our project.
The BCLK (3.072Mhz) is intermittent, If you talk to Microphone(Input to ADC), BCLK will output 3.072MHz, when there is no sound ,BCLK is 3.3V(high level).
We check…

Hi team
Here is a question we do not find the answer in the datasheet:
When the microphone input signal of the PMC6340Q1 chip is shorted to 18V battery, the MICBIAS voltage of the chip will be raised.
I know the normal programmable…
Part Number: PCM6340-Q1 Hi team,
I would like to share control command through I2C for the project using PCM6340 and the other project using PCM6360.
I plan to send a command to set the register which only exists in PCM6360 (ex Addr:0x0F ASI_CH5) to PCM6340…
Part Number: PCM6340-Q1 Hi team,
Dynamic channel pupd enable feature prohibit power down Channel 1 as below.
"1d = Channel can be powered up or down individually, even if channel recording is on. Do not powered-down channel 1 if this bit is set to…
