Figure 30. Serializer State Diagram, CDS = Low (LCD Application)
After power-up or when PWDN transitions from low to
high, the remote device (deserializer) starts up and tries
to lock to an incoming serial signal with sufficient power.
The host side (serializer) is in standby mode and does
not try to establish a link. Use the FC and program the
serializer to set SEREN = 1 (and apply a stable clock
signal) to establish a video link or CLINKEN = 1 to estab-
lish the configuration link. In this case, the deserializer
ignores the short wake-up signal sent from the serializer.
After power-up or when PWDN transitions from low to
high, the remote device (deserializer) starts up in sleep
mode. The high-speed link establishes automatically
after the serializer powers up with a stable clock signal
and sends a wake-up signal to the deserializer. Use this

mode in applications where the deserializer powers up
before the serializer.
For image-sensing applications, connect the FC to the
deserializer and set CDS = high for both the serializer
and deserializer. The deserializer powers up normally
(SLEEP = 0) and continuously tries to lock to a valid
serial input. Table 14 summarizes both startup cases,
based on the state of the serializer’s AUTOS pin.
After power-up, or when PWDN transitions from low to
high, the serializer locks to a stable input clock and
sends the high-speed data to the deserializer. The dese-
rializer locks to the serial data and outputs the video data
and clock.
