Description

for bus connected systems. Supplying Pin 1 of the SC-C1440 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 Reliability - NEL HALT/HASS qualified for

crystal oscillator start-up conditions

• Low jitter - Wavecrest jitter characterization avail-

able

• Wide frequency range—70.0 MHz to 165.0 MHz

• User specified tolerance available

• Will withstand vapor phase temperatures of 253°C

for 4 minutes maximum

• Space-saving alternative to discrete component

oscillators

• 1.8 Volt operation

• High shock resistance, to 1000g

• High Q crystal actively tuned oscillator circuit

• Power supply decoupling internal

• No internal PLL avoids cascading PLL problems

• High frequencies due to proprietary design

• Metal lid electrically connected to ground to

reduce EMI

• Gold plated pads

• RoHS Compliant, Lead Free Construction
