| CFPT-5300 SERIES ISSUE 1; 15 OCTOBER 2004 Delivery Options Please contact our sales office for current lead times Package Outline I I Low Profile DIL 14 resistance welded enclosure, hermetically sealed Description I Ageing I I I I The CFPT-5300 series of temperature compensated crystal oscillators (TCXOs), provide for ultra high stabilities down to 0.3ppm and operating temperature ranges as wide as -55 to 95C. Housed in an industry standard 4 pin DIL 14 package, the oscillator uses C-MAC's latest custom ASIC "Pluto" a single chip oscillator and , analogue compensation circuit. Its wide frequency range, operating temperature range, coupled with it's high stability and linear frequency pulling make it the ideal reference oscilator. Its ability to function down to supply voltage of 2.4V and low power consumption makes it suitable for a wide range of applications 1ppm 3ppm 2ppm 5ppm maximum maximum maximum maximum in first year, frequency < 20MHz for 10 years, frequency < 20MHz in first year, frequency > 20MHz for 10 years, frequency > 20MHz Frequency Stability Temperature: see table Supply Voltage Variation 10% < 0.2ppm* I Load co-efficient 15pF 5pF < 0.2ppm* * Dependent on frequency and output type I I Standard Frequency I Frequency Adjustment I 3.2, 4.096, 5.0, 6.4, 8.192, 9.6, 10.0, 12.8, 13.0, 14.4, 14.85, 16.384, 16.8, 19.2, 19.44, 19.8, 20, 32.768, 38.88, 40.0 MHz Non - standard frequencies in the range 1.25MHz to 40.0MHz are available on request, please contact our sales office Waveform I Square HCMOS 15pF load The following non-standard outputs are available on request, contact sales office: I Option A (standard): Control Voltage 1.5V1.0V, applied to pin 1 > 5ppm*, frequency < 20MHz > 7ppm, frequency > 20MHz Linearity <3% Slope Positive Input resistance >100k Modulation Bandwidth >2kHz Option B: > 5ppm *(>7ppm if frequency >20MHz) by means of an external 100k potentiometer connected as a variable resistor from pin 1 to GND I Square ACMOS 50pF max load Sinewave, > 1.0pk-pk, 10k // 10pF load Clipped Sinewave, >0.8Vpk-pk, 10k // 10pF load Sinewave and clipped sinewave signals are superimposed on a DC offset, to remove this offset insert an external coupling capacitor in series with the output * Higher adjustment range up to 50ppm and non standard control voltage ranges are available on request.
