ADC32J45: ADC32J45 Sync P?

Part Number: ADC32J45

DEARS.

I have a question in ADC32J45.

Does SYNCP work with Falling Edge?


Is it operating in a low state?


When Sync is "HIGH" Is "BCBC" output?


When "BCBC" is output, Test Pattern to Enable Test Pattern is output?

What is the precise meaning of the red box?

Thank you.

  • Henry,

    After SYNC goes low, the ADC will start sending K28.5 characters after the next start of the local multi frame clock. The device will continue to transmit the BCBC output until after SYNC goes high, which it will then send ILA data after the start of the next local multi frame clock period. The wording in Table 8 step 4 is a little confusing. The receiver will not pulse SYNC, but set it low until it receives at least 4 consecutive K28.5 characters on all lanes, which then it will set it back high.

    Regards,

    Jim
