5X7 mm Surface Mount

HCMOS 1.8V 850KHz to 165 MHz

Description

Features

Fixed frequency or tristate

Valpey Fisher’s R models surface

mount (SMD) oscillators provide

clock waveforms needed to clock

standard HCMOS circuits.

Very low power when tristated

Start up time less than 5 ms.

Stability options from +/-100 ppm to +/-25ppm

Guaranteed start-up with ramping DC supply

Typical Applications

CONNECTIONS

Any surface mount PCB that requires a standard

HCMOS/TTL 1.8V clock, including

Fixed Output Models

Tristate Models

microprocessors and microcontrollers

NOT USED

Floating or 1: Oscillator runs

Ground or 0: Tristate
