CFPT-9025 Series High Performance TCXO/TCVCXO Recommended for New Designs Package Outline ■ Delivery Options ■ Please contact our sales office for current leadtimes Description ■ 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 +125°C. 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 Ageing ■ ±1ppm maximum in first year ■ ±5ppm maximum for 10 years Frequency Stability ■ Temperature: see table ■ Typical Supply Voltage Variation ±10% < ±0.2 ppm ■ Typical Load Coefficient ±10% Standard Frequencies 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 A - Ageing adjustment: > ±5ppm (Standard Option) C - High Pulling ±10ppm to ±50ppm and non-standard control voltage ranges may be available depending on frequency and stability options.
