Part Number: PCM1861 Other Parts Discussed in Thread: PCM1791A , , PCM1863 Hello,
Our customer is considering to employ PCM186x and PCM179xA at TDM mode.
When look at PCM1791A datasheet, TDMCA mode is supported. In this case 2-BCK width LRCK is required…
Other Parts Discussed in Thread: PCM1791A , AM3352 Hi,
Background: we found that when tearing down ALSA, this can in rare cases cause the DAC (PCM1791A) to output digital noise even though the frame-clock and pcm data isn't running.
The issue is a bit…
Other Parts Discussed in Thread: PCM1791A Hi,
Looking at using the Silabs, Si5351 to get a flexible clock generator for a PCM1791A DAC. (24.576 MHz + 22.5792 MHz -> 256fS)
Using this clock generator, we'll get 100ps (max) jitter.
The other optionw…

Hi Wolfgang,
Thanks for reply. In my case, we're using a PCM1791A so have no flexible options of generating clocks from the DAC itself, so I guess best option here is to use an external PLL/Clock generator or buffered XO to a McAsp clock input to…
Other Parts Discussed in Thread: AM1808 , PCM1791A , PCM1851A Hi,
I am using an AM1808 and using the MCASP is a S/PDIF interface. I would like to support both 44.1KHz and 48KHz clock rates. Unfortunately I have a 12MHz crystal so I think I am in trouble…

PCM1972A has 67 level of current segment which can be known from Figure 65 of it's datasheet. And also some audio DAC like PCM1973 also has such figure in datasheet and…

Dear TI audio IC designers,
The PCM1791A audio DAC has the analog supply pins: Vccc(15), Vccf(21), Vccl(20), Vccr(10).
Some of them as: Vccc(15), Vccr(10) stays undecoupled SEPARATELY to analog ground according…
