Other Parts Discussed in Thread: PCM5310

Hi all,

When there are glitches or steps at the rising edge or falling edge on BCLK or LRCK,
how much will it allowed variation of the time and voltage of the glitch?

Hi all,
Is there the schmitt circuit on the input of BCLK/LRCLK?
If yes,
What voltage is the Vth/Vtl?
What is the minimum pulse duration?
Is the waveform acceptable?

Regards,
Toshi

Hi Toshi,

I don't have specifics on the timing specs of these lines. This waveform is most likely acceptable, and probably only as bad when the probe is used to measure the signal, adding capacitance to the trace that the part must drive. Is this with the PCM5310 in master mode?

Hi, Justin-san,
thanks for your reply.
PCM5310 is operated in slave mode.

Thanks and regards,
Toshi
