TLK2501: Receiver Clock recovery PLL bandwidth

Part Number: TLK2501

Hi Team,

 

Please advise me on questions bellows.

 

Q1.  Can you let me know the:

  1. Receiver Clock recovery PLL bandwidth
  2. Order of the PLL
  3. Dumping factor of the PLL

Q2   Please let me know the receiver side Eye mask.

 

Q3.   If GTX/CLK clock quality influence no the receiver performance?

   If so, are there any criterion on GTX/CLK clock quality.

 

We are experiencing receiver error problem and need to fix it shortly.

The answer to these questions helps us a lot.

  • Hi Mita-San,

    I checked on your question and am not able to find data for the parameters you noted. My colleague Rodrigo will be back next Monday or Tuesday and he has more information on this part. We will let you know either on Monday or Tuesday of next week.

    Regards,, Nasser

  • Nasser-san,

    Thank you for the status up date.

    I look forward to receive the answer sometime in next week.

  • Hi Mita, see inputs below.

    1. PLL questions
      • Receiver Clock recovery PLL bandwidth
        • Around 3 MHz

      • Order of the PLL
        • Info not available
      • Dumping factor of the PLL
        • Info not available
    2. Please let me know the receiver side Eye mask
      • Minimum VID spec is 200mV
      • Jitter tolerance is 0.6UI; jitter is Differential input jitter, random + deterministic, PRBS pattern at zero crossing
    3. If GTX/CLK clock quality influence no the receiver performance
      • Yes, of course
      • See guidelines below

    Reference Clock (TXCLK) Timing Requirements, over recommended operating conditions (unless otherwise noted)
