SJ-A1450 Series

Description

The

SJ-A1450 Series

of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals

for bus connected systems. Supplying Pin 1 of the SJ-A1450 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. All units are designed to

survive wave soldering operations without damage.

Features

• Wide frequency range– 4.0MHz to 40.0MHz

• 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

• Power supply decoupling internal

• No internal PLL avoids cascading PLL problems

• Low power consumption

• Gold plated leads

• TTL compatible (HCT) at specified supply voltage
