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
CC
Note (4). Internally AC coupled with CML output, but requires a 100Ohm differential termination at or
internal to Serializer/ Deserializer.
