The serializer includes a sleep mode to reduce power
consumption. The device enters or exits sleep mode by
a command from a local FC or a remote FC using the
control channel. Set the SLEEP bit to 1 to initiate sleep
mode. The serializer sleeps immediately after setting
its SLEEP = 1. The OUT+ and OUT- serial outputs each
have wake-up receiver to accept wake-up commands
from the attached deserializers. On power-up, the OUT+
wake-up receiver is enabled and the OUT- wake-up
receiver is disabled. Disable the wake-up receivers
(through ENWAKEP or ENWAKEN) if the devices are
disconnected or wake-up is not used in order to reduce
sleep-mode current. If both wake-up receivers are

FC connected to serializer.
Powers up.
Enables configuration link by
setting CLINKEN = 1 (if not
enabled automatically) and gets
an acknowledge. Waits for link
to be established (~3ms).
Writes one link configuration
bit (DRS, BWS, or EDC) in
the deserializer and gets an
acknowledge.
Writes corresponding serializer
link configuration bit and gets
an acknowledge.
Waits for link to be established
(~3ms) and then repeats steps
3 through 4 until all serial link
bits are configured.
Writes remaining configuration
bits in the serializer/deserializer
and gets an acknowledge.
Enables video link by setting
SEREN = 1 and gets an
acknowledge. Waits for link to
be established (~3ms).

Sets all configuration inputs. If any
configuration inputs are available
on one end of the link but not on
the other, always connects that
configuration input low.

disabled, the device can only be woken up from the local
control channel. To wake up the device, send an arbitrary
control-channel command to the serializer. Wait 5ms
for the chip to power up and then write 0 to the SLEEP
register bit to make the wake-up permanent.
The serializer has a power-down mode that further reduc-
es power consumption compared to sleep mode. Set
PWDN low to enter power-down mode. In power-down
mode, the serial outputs are in high impedance. Entering
power-down resets the device’s registers. Upon exiting
power-down, the state of the MS, DRS, CONF0, CONF1,
and AUTOS pins are latched.
STP Cable Drive
Sets all configuration inputs. If any
configuration inputs are available
on one end of the link but not on
the other, always connects that
configuration input low.
Powers up and loads default settings.
Locks to configuration link signal.
Configuration changed from default
