Description

The SC-B1420 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible

signals for bus connected systems. Supplying Pin 1 of the SC-B1420 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

• Wide frequency range–1.0MHz to 80.0MHz

• User specified tolerance available

• Will withstand vapor phase temperatures of 253°C

for 4 minutes maximum

• Space-saving alternative to discrete component

oscillators

• 2.5 Volt operation

• High shock resistance, to 1000g

• High Reliability - NEL HALT/HASS qualified for

crystal oscillator start-up conditions

• Low Jitter - Wavecrest jitter characterization

available

• No internal PLL avoids cascading PLL problems

• Metal lid electrically connected to ground to

reduce EMI

• Gold plated pads
