Function

RCLK

Output

B22

The receive clock (RCLK) output provides a timing

reference for the SPECTRA-622 receive line

interface outputs.

RCLK is a nominally 77.76 MHz, 50% duty cycle

clock. When clock recovery is enabled, RCLK is a

divide by eight version of the recovered clock.

When clock recovery is bypassed, RCLK is a divide

by eight version of the recovered RRCLK+/- inputs.

In parallel interface mode, PGMRCLK is a buffered

version of the PICLK input.

The RCLK output can be disabled and held low by

programming the RCLKEN bit in the SPECTRA-622

Clock Control register.

RFPO, SALM, LOF, LOS, OOF, LRDI and LAIS are

updated on the rising edge of RCLK.

RLAIS is sampled on the rising edge of RCLK.
