## **CFPT-9000 Series** 

## **ISSUE 9 ; 3 MARCH 2005** 

## **Recommended for New Designs** 

## **Delivery Options** 

- I Please contact our sales office for current leadtimes 

## **Description** 

- I A series of surface mountable 7.0 × 5.0mm temperature compensated voltage controlled crystal oscillators (TCVCXOs) for medium to high volume applications where small size and high performance are prerequisites.  This oscillator uses C-MAC’s latest custom ASIC "Pluto", a single chip oscillator and analogue compensation circuit, capable of sub 1 ppm performance over an extended temperature range.  Its ability to function down to a supply voltage of 2.4V and low power consumption make it particularly suitable for mobile applications 

## **RoHS compliance** 

- I Parts with the suffix ‘LF’ on the ordering code and part number are fully compliant with the European Union directive 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment.  Note: The RoHS compliant parts are suitable for assembly using both Lead-free solders (see Lead-free Reflow soldering profile) and Tin / Lead solders (see Tin / Lead Reflow soldering profile). 

## **Standard Frequencies**
