SJ-370 Series

Description

The SJ-370 Series of quartz crystal oscillators are designed to survive standard wave soldering operations
without damage.

Features

• Wide frequency range–2.25MHz 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

• High shock resistance, to 3000g

• Metal lid electrically connected to ground to reduce
EMI

• Low Jitter

• TTL compatible (HCT) at specified supply voltage

• High Q Crystal actively tuned oscillator circuit

• Low power consumption

• Power supply decoupling internal

• No internal PLL avoids cascading PLL problems

• High frequencies due to proprietary design

• Gold plated leads
