| CFPT-9025 Series High Performance TCXO/TCVCXO ISSUE 3; 1 FEBRUARY 2006 Package Outline Recommended for New Designs Delivery Options Low Profile, 7.6 x 9.3 x 3.2 mm SMD package with High Temperature Co-fired Ceramic base and metal cover Please contact our sales office for current leadtimes Ageing Description 1ppm maximum in first year 5ppm maximum for 10 years The CFPT-9025 series of temperature compensated crystal oscillators provide for ultra high stabilities down to 0.3ppm and operating temperature ranges as wide as -55 to +125C. The oscillator uses C-MAC's latest custom ASIC "Pluto", a single chip oscillator and analogue compensation circuit. Due to its unique mechanical construction the CFPT-9025 series is able to withstand 20,000 G's acceleration, which makes it the TCXO of choice for gun hardened GPS navigation systems Frequency Stability Temperature: see table Typical Supply Voltage Variation 10% < 0.2 ppm Typical Load Coefficient 10% < 0.1 ppm Frequency Adjustment Standard Frequencies Three options with external Control Voltage applied to pad 1: A - Ageing adjustment: > 5ppm (Standard Option) B - No frequency adjustment initial calibration @ 25C < 0.5 ppm SURFACE MOUNT TCXOs 9.6, 10.0, 11.68, 12.504, 12.8, 13.0, 14.4, 16.3676, 19.44, 20.0, 21.73875, 24.5535, 38.88, 40.96, 47.032, 49.152, 51.84 MHz Non-standard Frequencies in the range 1.0 MHz to 75.0 MHz (see table) are available on request, contact sales office.
