NAME

FUNCTION

1, 9, 16,

25, 32

VCC

Positive Supply Voltage. Bypass from VCC to VEE 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.

CLKSEL

Clock Select Input (Single-Ended). Drive low to select the CLK0, CLK0 input. Drive high to select the

CLK1, CLK1 input. The CLKSEL threshold is VBB. If CLKSEL is not driven by a logic signal, use a 1k

Ω

pulldown to VEE to select CLK0, CLK0, or a 1k

Ω pullup to VCC to select CLK1, CLK1.

CLK0

Noninverting Differential Clock Input 0. Internal 75k

Ω pulldown resistor.

CLK0

Inverting Differential Clock Input 0. Internal 75k

Ω pullup and pulldown resistors.

5VBB

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

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

CLK1

Noninverting Differential Clock Input 1. Internal 75k

Ω pulldown resistor.

CLK1

Inverting Differential Clock Input 1. Internal 75k

Ω pullup and pulldown resistors.
