Differential Positive ECL (DPECL)SK-A29C0 Series

Description

The SK-A29C0 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 - 60.0MHz to 350.0MHz ? User specified tolerance available ? Case at electrical ground

? Will withstand vapor phase temperatures of 253°C for 4 minutes maximum

? All metal, resistance weld, hermetically sealed package

? 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

? High frequencies due to proprietary design CRYSTAL CLOCK OSCILLATORS
