Part Number: PCM1681 Hello,
A noisy PCM1681 was found with PPM generation, there are same sample devices in our hands.
Please look at attached waveform.
In this SE voltage output DAC, Vout swing is reference from Vcom as Bi-Pore Zero level.
But our sample…
Part Number: PCM1681 Hello expert, My customer has question for PCM1681's clock timing requirement for SCK and LRCK/BCK. Their system has possibility to input the SCK for PCM1681 which is not synchronized with LRCK/BCK regarding phase. So I'd like to…
Part Number: PCM1681 Hi expert, I asked SCK LRCK/BCK timiing requirement in this thread previously. I have question regarding above thread. In in-phase case, SCK’s rising edge will appear 128 time normally. However if we consider about worst case from jitter…
Part Number: PCM1681 Hi team,
Let me ask 2 questions.
TI recommends to use external LPF at output of DAC to reduce out of band noise. If user don't use the external LPF for PCM1681 which have internal LPF, is there any problem? According to the E2E…
Part Number: PCM1681 Hello expert, I have question regarding I2C communication regarding PCM1681. This device support up to 100kHz I2C commutation but this device connect to I2C bus which is connected other device that used 333kHz I2C. My understanding of…
Part Number: PCM1681 Other Parts Discussed in Thread: PCM1754 , , PCM1742 Hi professional, I ask about whether there is specification difference regarding noise between 128fs and 256fs regarding PCM1754 on this E2E . I'd like to same point with PCM1681.…
Part Number: PCM1681 Hello team,
PCM1681 have 2 modes, narrow and wide.
All of electrical characteristics are specified with narrow mode. Is there any spec difference between narrow mode and wide mode?
I care about difference about audio quality and current…
