Note (1). A (TX)+ B (RX) = 300mA

(A: Not include termination circuit; B: using a resister of 150Ω between Data-output and ground)

Note (2). There is an internal 4.7 to 10kΩ pull-up resistor to VccT.
Note (3). Pull up to V

on host Board.

Note (4). Internally AC coupled with CML output, but requires a 100Ohm differential termination at or

internal to Serializer/ Deserializer.
