CFPT-9025 Series High Performance TCXO/TCVCXO

ISSUE 3; 1 FEBRUARY 2006

Recommended for New Designs

Delivery Options

Package Outline

■

Low Profile, ꢀ6 x 9ꢀ. x .ꢀ2 mm SMD package with High

Temperature Co-fired Ceramic base and metal cover

Description

1ppm maximum in first year

■

The CFPT-9025 series of temperature compensated

■

5ppm maximum for 10 years

crystal oscillators provide for ultra high stabilities down

to 0ꢀ.ppm and operating temperature ranges as wide as

–55 to +125°CꢀThe oscillator uses C-MAC’s latest custom

ASIC "Pluto", a single chip oscillator and analogue

compensation circuitꢀ Due to its unique mechanical

construction the CFPT-9025 series is able to withstand

20,000 G’s acceleration, which makes it theTCXO of

choice for gun hardened GPS navigation systems
