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
