Clock line for the bidirectional control bus communication
SCL requires an external pull-up resistor to V

SDA requires an external pull-up resistor to V
I
MODE = L, Master mode (default); Device generates and drives the SCL clock line.
Device is connected to slave peripheral on the bus. (Serializer initially starts up in
Standby mode and is enabled through remote wakeup by Deserializer)
MODE = H, Slave mode; Device accepts SCL clock input and attached to an I
controller master on the bus. Slave mode does not generate the SCL clock, but
uses the clock generated by the Master for the data transfers.
Device ID Address Select
Resistor to Ground and 10 kΩ pull-up to 1.8V rail. See
Power down Mode Input Pin.
PDB = H, Serializer is enabled and is ON.
PDB = L, Serailizer is in Power Down mode. When the Serializer is in Power Down,
the PLL is shutdown, and IDD is minimized. Programmed control register data are
NOT retained and reset to default values
Reserved.
This pin MUST be tied LOW.
Non-inverting differential output, bidirectional control channel input. The
interconnect must be AC Coupled with a 100 nF capacitor.
