Description
The SR-A2A70 Series of quartz crystal oscillators provide Differential Sine Wave signals. This device is to
operate using positive voltage and uses multiple ground pins for improved signal integrity.
Features
• Wide frequency range – 250MHz to 700MHz
• Low noise analog multiplication
• 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
• High shock resistance, to 1000g
• COTS/Dual use
