Pin Function
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 50Ω. 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
(IN, /IN). For AC-coupled applications, connect VREF_AC to the VT pin and bypass with a
0.01µF low ESR capacitor to V
The single-ended TTL/CMOS-compatible inputs select the inputs to the multiplexer. Note that
this input is internally connected to a 25kΩ pull-up resistor and will default to a logic HIGH state
if left open.
Positive Power Supply. Bypass with 0.1µF0.01µF low ESR capacitors as close to each VCC
pin.
Differential Outputs: These 400mV LVPECL output pairs are the outputs of the device. Each
output is designed to drive 400mV into 50Ω terminated V
Unused output pairs may be left open.
Ground. GND and exposed pad must both be connected to the most negative potential of chip
ground.
