Pin Description

SOT23

NAME

FUNCTION

VBB

Reference Output Voltage. Connect to the inverting or noninverting data input to provide a reference

for single-ended operation. When used, bypass with a 0.01µF ceramic capacitor to VCC; otherwise,

leave it open.

GND

Ground. Provide a low-impedance connection to the ground plane.

Inverted LVPECL Data Input. 36.5k

Ω pullup to VCC and 75kΩ pulldown to GND.

Noninverted LVPECL Data Input. 75k

Ω pullup to VCC and 75kΩ pulldown to GND.

VCC

Positive Supply Voltage. Bypass VCC to GND with 0.1µF and 0.01µF ceramic capacitors. Place the

capacitors as close to the device as possible with the smaller value capacitor closest to the device.

Noninverted LVDS Output. Typically terminate with 100

Ω to Q.

Inverted LVDS Output. Typically terminate with 100

Ω to Q.

N.C.

No Connection. Not internally connected.
