UNIT

VTX-CM-IDLE-DELTA

Transmitter idle common

mode voltage change U2/U3

state.

Max allowed instantaneous commode-

mode voltage at connector side of AC

coupling capacitor. This is an absolute

voltage spec referenced to the receive

side termination ground.

VTX-DC-CM

TX DC common mode voltage 1200mVpp linear range setting;

1.85

2.05

VTX-CM-AC-PP-ACTIVE

Transmitter AC common

mode peak-peak voltage in

U0. Maximum mismatch from

TXP+TXN for both time and

amplitude.

1200mVpp linear setting; CHx_EQ

setting matches input channel insertion

loss;
