Features and Operation (Continued)

When the Deserializer’s PD* signal is de-asserted, the WC

output will power up and initialize the serializer and start

transmitting the clock reference. Once the Serializer re-

ceived the clock, it waits seven cycles, and then outputs the

clock signal. Seven cycles later, the Serializer’s PLL will

begin to lock if PCLK is present.

When the Deserializer’s PD* signal is asserted, the WC

signal is turned off.

MISC. Definitions:
