CRYSTAL CLOCK OSCILLATORS

Rev. L

CMOS

HS-420 Series

Description

The HS-420 Series of quartz crystal oscillators are resistance welded in an all metal package, offering RFI

shielding, and are designed to survive standard wave soldering operations without damage. Insulated

standoffs to enhance board cleaning are standard.

Features

• Wide frequency range–244.0Hz to 625.0kHz

• User specified tolerance available

• Capable of driving 3TTL Loads

• Low Jitter

• Will withstand vapor phase temperatures of 253°C • High Q Crystal actively tuned oscillator circuit

for 4 minutes maximum

• Space-saving alternative to discrete component

oscillators

• High shock resistance, to 3000g

• All metal, resistance weld, hermetically sealed

package

• Power supply decoupling internal

• No internal PLL avoids cascading PLL problems

• Gold plated leads - Solder dipped leads available

upon request

• RoHS Compliant, Lead Free Construction

(unless solder dipped leads are supplied)
