HS-1420 Series

Description

The HS-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals

for bus connected systems. Supplying Pin 1 of the HS-1420 units with a logic “1" or open enables its

output. In the disabled mode, output pin presents a high impedance to the load. All units 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– 0.5MHz to 85MHz

• User specified tolerance available

• Low Jitter

• High Q Crystal actively tuned oscillator circuit

• Will withstand vapor phase temperatures of 253°C • Power supply decoupling internal

for 4 minutes maximum

• Space-saving alternative to discrete component

oscillators

• No internal PLL avoids cascading PLL problems

• Low power consumption

• Gold plated leads - Solder dipped leads available

upon request

• High shock resistance, to 3000g

• All metal, resistance weld, hermetically sealed
