DS90UR903Q Datasheet, PDF (26/34 Pages) Texas Instruments – DS90UR903Q/DS90UR904Q 10 - 43MHz 18 Bit Color FPD-Link II Serializer and Deserializer
The High Speed Serial Channel is a 28-bit symbol composed
of 21 bits of data containing video data & control information
transmitted from Serializer to Deserializer. CLK1 and CLK0
represent the embedded clock in the serial stream. CLK1 is
always HIGH and CLK0 is always LOW. This data payload is
optimized for signal transmission over an AC coupled link.
Data is randomized, balanced and scrambled.
DESCRIPTION OF SERIAL CONTROL BUS
ID[X] ADDRESS DECODER
The ID[x] pin is used to decode and set the physical slave
address of the Serializer/Deserializer (I2C only) to allow up to
six devices on the bus using only a single pin. The pin sets
one of six possible addresses for each Serializer/Deserializer
device. The pin must be pulled to VDD (1.8V, NOT VDDIO))
with a 10 kΩ resistor and a pull down resistor (RID) of the
recommended value to set the physical device address. The
recommended maximum resistor tolerance is 0.1% worst
case (0.2% total tolerance).
