CRYSTAL CLOCK OSCILLATORS

Rev. G

CMOS

HS-A1440 Series

Description

The HS-A1440 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals

for bus connected systems. Supplying Pin 1 of the HS-A1440 units with a logic “1" or open enables its pin 8

output. In the disabled mode, pin 8 presents a high impedance to the load.

Features

• Wide frequency range– 70.1MHz to 125.0MHz

• 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 1000g

• All metal, resistance weld, hermetically sealed

package

• RoHS Compliant, Lead Free Construction

(unless solder dipped leads are supplied)

• 3.3 Volt operation
