Hi Experts,
Our customer is evaluating TLK10002 now and following the datasheet page 66 register configuration. They used one BER Analyzer to send the PRBS31/PRBS7 signals with data rate 4.9152Gbps to INA and HSRXA, then test the signals on OUTA and HSTXA, but no any eye diagram observed.
Customer's setup is as below:
1. Pin Refclk_sel=1, select Refclk 122.88MHz as the reference clock, pin Refclk0 connected to ground through 100ohm resistor.
2. Registers can be written and read correctly. Registers 0x01=0x3302, 0x03=0xA545, 0x06=0x1119, others are the default value.
Questions:
Is there any issues for the register settings? Is there any other design considerations for this part to work correctly? Is it the correct method to test this device by using the BER analyzer to test the eye diagram on pin OUTA and HSTXA?
Thanks.
