Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs accept
AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally terminates to a VT
pin through 50
. Note that these inputs will default to an indeterminate state if left open.
Please refer to the “Input Interface Applications” section for more details.

Input Termination Center-Tap: Each side of the differential input pair terminates to a VT pin.
The VT pins provide a center-tap to a termination network for maximum interface flexibility.
See “Input Interface Applications” section for more details. For a CML or LVDS inputs, the VT
pin is left floating.

Reference Voltage: This output biases to V

–1.2V. It is used when AC coupling the inputs
(IN, /IN). For AC-coupled applications, connect VREF_AC to the VT pin and bypass with a
0.01

F low ESR capacitor to V
CC
. See “Input Interface Applications” section for more details.

The single-ended TTL/CMOS-compatible inputs select the inputs to the multiplexer. Note that
this input is internally connected to a 25k
pull-up resistor and will default to a logic HIGH state
if left open.

Differential Outputs: These 400mV LVPECL output pairs are the outputs of the device. Each
output is designed to drive 400mV into 50
terminated V
