Description
LOCK
LOCK goes low when the Deserializer PLL locks onto the
embedded clock edge. CMOS level output. Totem pole output
structure, does not directly support wired OR connections.
Recovered Clock. Parallel data rate clock recovered from
embedded clock. Used to strobe ROUT, CMOS level output.
Output Enable. TTL level input. When driven low, TRI-STATEs
ROUT0–ROUT9 and RCLK.

1) LOCK Active indicates the LOCK output will reflect the state of the Deserializer with regard to the selected data stream.
2) RCLK Active indicates the RCLK will be running if the Deserializer is locked. The Timing of RCLK with respect to ROUT is determined by RCLK_R/F.
3) ROUT and RCLK are TRI-STATED when LOCK is asserted High.
4) During Power-up.
