CRYSTAL CLOCK OSCILLATORS
Differential Positive ECL (DPECL)
SR-A29B0 Series
Data Sheet 0447G
Rev. M
Description
The SR-A29B0 Series of quartz crystal oscillators provide DPECL Fast Edge compatible signals. This
device is to operate using positive voltage and uses multiple ground pins for improved signal integrity. This
device is intended to operate on positive voltage for PECL applications.
Features
• Wide frequency range - 250.0MHz to 1.7GHz
• 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
