FEATURES

• Spread Spectrum Clock Generator with integrated

6x frequency multiplier.

• Input frequency range: 10MHz to 30MHz

• Output frequency range: 60MHz to 180MHz.

• Accepts input from external clocks or crystal.

• Selectable Center Spread SST modulation

amplitude.

• Output Enable feature (OE).

• TTL/CMOS compatible outputs.

• 3.3V Operating Voltage.

• Low short term jitter.

• Available in 8-Pin 150mil SOIC.

DESCRIPTION

The PLL701-14 is a Spread Spectrum Clock

Generator designed to reduce EMI in high-speed

digital systems. Its spread spectrum modulation

amplitude is selectable via the input selector pins.

The chip multiplies any input from 10MHz to 30MHz

by 6x. The chip provides an output Enable/Disable

input permitting the user to tri-state the output.

PIN CONFIGURATION

Note: ^: Internal pull-up resistor (30 k

Ω).
