- 差分输入
The high-speed digital inputs (DATA0/NDATA0,RCV0/NRCV0, DATA1/NDATA1, and RCV1/NRCV1) are intended for use with a high-speed differential signal source such as LVDS, LVPECL, ECL, etc.
DATA_, NDATA_, RCV_,NRCV_ to GND..............................(VEE - 0.3V) to (VBV_ + 0.3V)
DATA_ to NDATA_, RCV_ to NRCV_ .....................................±1V

- 偏置电压Bias Voltage 也叫失调电压 OffsetVoltage，负责将输入信号设定在合适的静态直流点上。
- 对于LVDS接口，Vos 或 Vicm=1.2V （Input Common Mode）
- 差分输出
The board power supply (VTRM) is the voltage used to terminate the comparator outputs on the IC.Setting VTRM to +1.2V makes the high-speed digital I/Os compatible with LVDS levels.
CH_, NCH_, CL_, NCL_ to GND..............-1.5V to (VCTV_ + 0.3V)
Current into CH_, NCH_, CL_, NCL_................................±35mA
-
- 终端电压Termination Voltage也叫共模输出Output Common Mode，将输出设置在合适的直流点上，以满足下级输入器件的要求。
- 对于LVDS接口，一般设置Vocm=1.25V
