MPC8313 GPCM LCLK Output Jitter

Is there any information on how much jitter can be expected on the GPCM LCLK output.

I couldn't find any information in the MPC8313EEC (MPC8313E PowerQUICC II Pro Processor Hardware Specifications, Rev. 4)

Thanks

Chris

We do not have the 83137 LCLK jitter specs

However some measurements have been done:

Average jitter is 230ps, max jitter 420ps

Are those jitter measurements made from the MPC8313E reference design board? And are they RMS or Pk-Pk?

Bump, RMS or PK-PK?
