Description
The SH-A368X Series of voltage controlled quartz crystal oscillators provide frequency
control by applying a voltage to Pin 1. This unit supplies DPECL compatible outputs which are
enabled when Pin 2 is set to a logic low or left open.
Features
• Frequency range–60.0MHz to 200.0MHz
• Wide Absolute Pull Range
• Will withstand SMD reflow temperatures
of 253°C for 4 minutes maximum
• Space-saving alternative to discrete
component oscillators
• High shock resistance, to 1000g
• 3.3 volt operation
• Metal lid electrically connected to ground
to reduce EMI
• Low Jitter - Wavecrest jitter characterization
available
• High Reliability - NEL HALT/HASS
qualified for crystal oscillator start-up
conditions
• High Q Crystal actively tuned oscillator
circuit
• Power supply decoupling internal
• No internal PLL avoids cascading
PLL problems
• High frequencies due to proprietary design
• Gold plated pads
• RoHS Compliant, Lead Free Construction

Footnotes:
1) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization.
RMS jitter bandwidth of 12kHz to 20MHz.
2) Frequency increase with increase in control voltage and is monotonic.
3) Logic levels are dependant on specified load of 50 ohms to Vcc-2 volts
4) Pullability is frequency dependant. Consult factory.
