Tool/software:
Hi,
I am providing GTX_CLK, wanting system to work at 31 MHz for reading data only : RX[0:15]
I noticed that providing providing sine wave signal at 31MHz on GTX_CLK within the required volt range does the job.
I wanted to verify if the system working on sine wave is total luck or not and if I do indeed need a square wave signal ?
Per the reference clock input definition in the datasheet (below) it seems like as long as we provide necessary valid frequency input through GTX_CLK it will function for our reading operation.
Thanks
"reference clock input The reference clock (GTX_CLK) is an external input clock that synchronizes the transmitter interface. The reference clock is then multiplied in frequency 10 times to produce the internal serialization bit clock. The internal serialization bit clock is frequency-locked to the reference clock and used to clock out the serial transmit data on both its rising and falling edge, providing a serial data rate that is 20 times the reference clock. "
