IN0, /IN0
IN1, /IN1
Differential Inputs: These input pairs are the differential signal inputs to the device.
These inputs accept AC- or DC-coupled signals as small as 100mV (200mVpp). Each
pin of a pair internally terminates to a VT pin through 50. Please refer to the “Input
Interface Applications” section for more details.
4, 9
VREF-AC0
VREF-AC1
Reference Voltage: These outputs bias to VCC –1.2V. They are used for AC-coupling
inputs IN and /IN. Connect VREF-AC directly to the corresponding VT pin. Bypass with
0.01F low ESR capacitor to VCC. Due to the limited drive capability, the VREF-AC pin
is only intended to drive its respective VT pin. Maximum sink/source current is
±1.5mA. Please refer to the “Input Interface Applications” section for more details.
3, 8
VT0, VT1
Input Termination Center-Tap: Each side of the differential input pair terminates to a
VT pin. The VT0 and VT1 pins provide a center-tap to a termination network for
maximum interface flexibility. Please refer to the “Input Interface Applications” section
for more details.

VCC
Positive Power Supply: Bypass with 0.1F||0.01F low-ESR capacitors as close to
the VCC pins as possible.
