Other Parts Discussed in Thread: PCM1863, PCM1865, PCM1864

Hi TI experts,

I am studying the spec of PCM 1863 , I hope to confirm some features of it.

1) Is DOUT_2 is available in PCM1863 through GPIO 0/1/2/3 ? Can I use all the GPIO 0 & 1 & 2 & 3 in once for DOUT_2 ?

2) Is DIN is available in PCM 1863 through GPIO 0/1/2/3 ?

3) Can I use different GPIO pin for DIN and DOUT_2 in once ? (e.g. GPIO_0 for DIN meanwhile GPIO_1 & 2 & 3 for DOUT_2)

5) In master mode can I just input I2S Audio Data to DIN only without BCK & LRCK ) : Will DOUT & DOUT_2 's audio data be synchronised automatically with the BCK & LRCK output ?

6) Can I use DIN only without mixing it with Analog input channel ?

7) Can I use digital gain only without analog gain when there is only DIN input ?

Thank you very much

Hi Fai,

1. DOUT 2 is not available on PCM1863 since it is a 2 channel device, it is available on PCM1864 and PCM1865.

2. DIN is available on PCM1863.

3. On the PCM1864 and PCM1865 yes, but DOUT2 is not available on PCM1863.

5. BCK and LRCK must be synchronous with the data, therefore if the PCM1863 is the master, BCK and LRCK should be sent to the source of the audio data to use to clock the audio data.

6.DIN is available in every mixer. You can output DIN by itself without mixing, if you sacrifice one of the ADC channels. You cannot output both ADC channel and the DIN data at the same time without mixing on the PCM1863.

7.DIN is sourced to every mixer, which has the ability to gain the signal digitally by up to 18 dB.
