Differential Positive ECL (DPECL)

HA-2870 Series

Description

The HA-2870 Series of quartz crystal oscillators provide MECL 10K and 10KH series compatible signals in

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

effective packaged PECL oscillators to meet their timing requirements.

Features

• Wide frequency range–18.0MHz 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 5, complement on Pin 1

• 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

• RoHS Compliant, Lead Free Construction

(unless solder dipped leads are supplied)
