PCM4202: PCM4202DBR

Shiva Kiran

Part Number: PCM4202

Tool/software:

Hello,

For the part number PCM4202DBR, referring to Figure 16 in datasheet, clarification required on LRCK and BCK clock assertion timings.

The LRCK changing position and BCK changing position have some skewed(/shifted) which is marked in red arrows in below image for your reference.

1.Does this shifting in position required?

2.If yes, what is timing requirement for this shifting?

Hi Shiva,

Sorry for the delay in responding. This skew in BCLK-FSYNC is not needed.

Thanks and Regards,

Hello Lakshmi Narasimhan,

The Skew what we are looking is between BCK and LRCK, attached the snapshot with marking in earlier query.

Does your response mean, the skew between between BCK and LRCK is not required? Please confirm

(As FSYNC mentioned in your response is not found in datasheet)
