22-Bit GMSL Serializer with Coax or
STP Cable Drive
Note 2: To provide a midlevel, leave the input open, or, if driven, put driver in high impedance. High-impedance leakage current
must be less than Q10µA.
Note 3: I

min due to voltage drop across the internal pullup resistor.
Note 4: Specified pin to ground.
Note 5: Specified pin to all supply/ground.
Note 6: Guaranteed by design and not production tested.
Note 7: Measured in serial link bit times. Bit time = 1/(30 x f
PCLKIN)
for BWS = 0. Bit time = 1/(40 x f
