CSMF, VSMF series

Raltron Electronics has introduced two families of products that allow users to select of frequencies from either a clock or voltage-controlled oscillator.

Within a frequency range of from 10MHz to 1200MHz, both new CSMF and VSMF series are based on an advanced Digital PLL Platform that can be pre-programmed for up to two different output frequencies. This flexibility significantly reduces design and turnaround costs.

Both series incorporate a low frequency crystal with low jitter synthesis to provide a wide range of frequencies. Both the CSMF clock and VSMF voltage controlled units are available in LVCMS, LVPECL and LVDS output formats making the VSMF aptly suitable for SONET/SDH, Gigabit Ethernet, clock/data recovery and DSL with the CSMF units additionally useful in Fibre Channel applications.

Operating voltage for both the CSMF clocks and VSMF voltage controlled units are from 2.5V to 3.3V @ 35mA to 45mA within their frequency range of 10MHz to 1200MHz with RMS phase jitter at 0.8ps typ. within an operating temperature range of from -40°C to +85°C. Units are supplied in a 5mm x 7mm ceramic package.

The Raltron dual frequency CSMF and VSMF oscillators are available within four weeks for sampling requirements with production quantities at six to eight weeks ARO. Current pricing is at $ 9.75 each for CSMF units and $14.75 for VSMF's in quantities of 1K pieces.
