LVDS
SR-A2D30 Series
PATENT PENDING
Data Sheet 0547A
Rev. B
Description
The SR-A2D30 Series of quartz crystal oscillators provides a LVDS compatible signal. This device uses
multiple ground pins for improved signal integrity.
Features
• Wide frequency range - 250.0MHz to 750.0MHz
• Patent Pending, harmonic multiplication for
extremely low jitter
• High frequency output eliminates the need for PLL
multiplication
• Stabilities over temperatures as low as ±20ppm
eliminates SAW oscillator temperature problems
• 3.3V and 2.5V version available
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• User specified tolerance available
• Cover connected to ground
• Will withstand SMD reflow temperatures of 183°C
for 4 minutes maximum
• High shock resistance, to 1000g

2) Open to Enable pin also enables the output.
3) Standard frequency stability (others available)
4) Phase Noise characterization available. Phase Noise
is frequency dependant, phase noise specification
references a 1.0GHz part.
5) RMS jitter bandwidth of 12kHz to 20MHz
