SR-A2D30 Series
PATENT PENDING
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
