Notes:
13. REFCLK has no phase or frequency relationship with RXCLK and only acts as a centering reference to reduce clock synchronization time. REFCLK must be
within
±
200- ppm (
±
0.02%) of the transmitter PLL reference (REFCLK) frequency, necessitating a
±
100-ppm crystal.
14. While sending continuous K28.5s, outputs loaded to a balanced 100
load, over the operating range.
15. While sending continuous K28.7s, after 100,000 samples measured at the cross point of differential outputs, time referenced to REFCLK input, over the
operating range.
16. Static alignments is a measure of the alignment of the Receiver sampling point to the center of a bit. Static alignment is measured by sliding one bit edge in
3,000 nominal transitions until a character error occurs.
17. Receiver UI is calculated as 1/Fref*10 when RXRATE = LOW if no data is being received of the remote transmitter. If data is being received it is equal to
1/transmit serial bit rate.
18. Error Free Window is a measure of the time window between the bit centers where a transition may occur without causing a sampling error. It is measured
over the operational range.
