•  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

DIFFERENTIAL CONTROL INPUTS (DATA_, NDATA_, RCV_, NRCV_)

Input High Voltage -1.6 ～ +3.5 V
Input Low Voltage  -2.0 ～ +3.1 V
Differential Input Voltage ±0.15 ～ ±1.0 V

 

•  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
