CRYSTAL CLOCK OSCILLATORS

LVCMOS (1.8V)

SJ-C1440 Series

Data Sheet 0210A

Rev. C

PRELIMINARY

Description

The SJ-C1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible

signals for bus connected systems. Supplying Pin 1 of the SJ-C1440 units with a logic “1" or open enables

its pin 3 output. In the disabled mode, pin 3 presents a high impedance to the load.

Features

• Wide frequency range– 30.0MHz to 100.0MHz

• 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

• Metal lid electrically connected to ground to reduce

EMI

• High Q Crystal actively

tuned oscillator circuit

• High Reliability - NEL HALT/HASS qualified for

crystal oscillator start-up conditions

• Low Jitter - Wavecrest jitter characterization

available

• 1.8Volt operation

• Power supply decoupling internal

• No internal PLL avoids cascading PLL problems

• Low power consumption

• Gold plated leads
