SJ-A1440

Series

Frequency Range: 10.0 MHz to 250.0 MHz

Description

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

for bus connected systems. Supplying Pin 1 of the SJ-A1440 units with a logic “1” or open enables its Pin 3

output. In the disable mode, Pin 3 presents a high impedance to the load.

Features

• High shock resistance, to 3000g

• Metal lid electrically connected to ground to

reduce EMI

• High Reliability - NEL HALT/HASS qualified for

crystal oscillator start-up conditions

• Low jitter - Wavecrest jitter characterization avail-

able
