Pin Function
LVDS Differential (Outputs): Normally terminated with 100ý across the pair (Q, /Q). See “LVDS
Outputs” section, Figure 2a. Unused outputs should be terminated with a 100ý resistor across
each pair.
This single-ended TTL/CMOS-compatible input functions as a synchronous output enable. The
synchronous enable ensures that enable/disable will only occur when the outputs are in a logic
LOW state. Note that this input is internally connected to a 25ký pull-up resistor and will default
to logic HIGH state (enabled) if left open.
Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs
accept AC- or DC-Coupled differential signs as small as 100mV. Each pin of a pair internally
terminates to a VT pin through 50ý. Note that these inputs will default to an intermediate state if
left open. Pleae refer to the “Input Interface Applications” section for more details.
Reference Voltage: These outputs bias to V
inputs (IN, /IN). For AC-Coupled applications, connect VREF-AC to VT pin and bypass with
0.01µF low ESR capacitor to V
Maximum sink/source current is ±1.5mA. Due to the limited drive capability, each VREF-AC pin
is only intended to drive its respective VT pin.
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 detaiils.
