External Reference Clock
The external reference clock selection and its interface are a critical part of system applications for this product.
Table 38 species reference clock requirements, over the full range of operating conditions. The designer is
encourage to read TN1040, SERDES Reference Clock, which discusses various aspects of this system element
and its interconnection.
Table 38. Reference Clock Specications (REFCLKP and REFCLKN)
Embedded Core Timing Characteristics
Table 39 summarizes the end-to-end latencies through the embedded core for the various modes. All latencies are
given in clock cycles for system clocks at half the REFCLK_[A:B] frequency. For a REFCLK_[A:B] of 156.25 MHz, a
system clock cycle is 6.4 ns.

1. With multi-channel alignment, the latency is largest when the skew between channels is at the maximum that can be correctly
compensated for (18 clock cycles). The latency specied in the table is for data from the channel received rst.
