Notes:
1.
Measurement Conditions: Tested sending 1250 MBd PRBS 27-1 sequence from a serial Bit Error Rate Tester (BERT) with DOUT± outputs
terminated with 150Ω resistors to GND.
2.
Typical values are at VCC = 3.3 volts.

Note:
1.
The transmitter latency, as shown in Figure 4, is dened as the time between the latching in of the parallel data word (as triggered by the rising
edge of the transmit by clock, REFCLK) and the transmission of the rst serial bit of that parallel word (dened by the rising edge of the rst bit
transmitted).
