Description

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 95°C. 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 Standard Frequency

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 Square ACMOS 50pF max load I Sinewave, > 1.0pk-pk, 10kΩ // 10pF load I Clipped Sinewave, >0.8Vpk-pk, 10kΩ // 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 Supply Voltages I 3.3V or 5.0V (non standard supply voltages in the range 2.4V to 6.0V are available on request, please contact our sales office) Current Consumption I HCMOS Typically » 1+Frequency(MHz)*Supply(V)*{Load(pF)+15}*10-3mA Eg 20MHz, 5V, 15pF » 4mA I Sinewave, < 8mA I Clipped sinewave, 1+Frequency(MHz)*1.2*{Load(pF)+30}*10-3mA Package Outline I Low Profile DIL 14 resistance welded enclosure, hermetically sealed Ageing I ±1ppm maximum in first year, frequency < 20MHz I ±3ppm maximum for 10 years, frequency < 20MHz I ±2ppm maximum in first year, frequency > 20MHz I ±5ppm maximum for 10 years, frequency > 20MHz Frequency Stability I Temperature: see table I Supply Voltage Variation ±10% <±0.2ppm* I Load co-efficient 15pF ±5pF < ±0.2ppm* * Dependent on frequency and output type Frequency Adjustment I Option A (standard): Control Voltage 1.5V±1.0V, applied to pin 1 > ±5ppm*, frequency < 20MHz > ±7ppm, frequency > 20MHz Linearity < 3% Slope Positive Input resistance >100k Ω Modulation Bandwidth >2kHz I Option B: > ±5ppm *(>±7ppm if frequency >20MHz) by means of an external 100kΩ potentiometer connected as a variable resistor from pin 1 to GND * Higher adjustment range up to ±50ppm and non standard control voltage ranges are available on request.
