Pin Function
LVDS Differential (Outputs): Normally terminated with 100Ω across the pair (Q, /Q). See “LVDS
Outputs” section, Figure 2a. Unused outputs should be terminated with a 100Ω 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 25kΩ 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 50Ω. 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.
Ground. GND pins and exposed pad must be connected to the most negative potential of the
device ground.
Positive Power Supply: Bypass with 0.1µF//0.01µF low ESR capacitors and place as close to
each VCC pin as possible.
