SURFACE MOUNT CLOCK OSCILLATOR

CSMF SERIES:

Multi-Frequency Oscillator with Low Jitter Output 10MHz – 1200MHz

PRODUCT DESCRIPTION

The CSMF clock series is a cutting edge family of High Frequency, Low Jitter Output, Multi-Frequency Clock

Oscillators based on an advanced digital PLL platform. The CSMF clocks are available in a 7x5mm ceramic

package with output frequency from 10MHz to 1.2 GHz. The CSMF units are pre-programmed with up to 2

different output frequencies, any of which are user selected. Such flexibility significantly reduces design cycle

time and overall cost. The CSMF clock design incorporates a low frequency crystal along with low Jitter

frequency synthesizer to provide a wide range of frequencies. The CSMF Clocks are available in LVCMOS,

LVPECL and LVDS outputs, making them suitable for a wide range of applications.
