CRYSTAL CLOCK OSCILLATORS

Positive ECL (PECL) - Enable/Disable

HS-1870 Series

Data Sheet 9207A

Rev. S

Description

The HS-1870 Series of quartz crystal oscillators provide MECL 10K and 10KH series compatible signals in

industry standard four-pin DIP hermetic packages. Systems designers may now specify space-saving,

cost-effective packaged PECL oscillators to meet their timing requirements. This device is intended to

operate on positive voltage for PECL applications.

Features

• Wide frequency range–90.0MHz to 250.0MHz

• User specified tolerance available

• Will withstand vapor phase temperatures of 253°C

for 4 minutes maximum

• Space-saving alternative to discrete component

oscillators

• High shock resistance, to 3000g

• All metal, resistance weld, hermetically sealed

package

• Low Jitter

• MECL 10K and 10KH series compatible output

on Pin 8

• High Q Crystal actively tuned oscillator circuit

• Power supply decoupling internal

• No internal PLL avoids cascading PLL problems

• High frequencies due to proprietary design

• Gold plated leads - Solder dipped leads available

upon request
