CFPT-9050 SMD TCVCXO

iSSUE 8; 1 NOVEMBER 2008 - RoHS 2002/95/EC

Supply Current

▪

Description

0.3ppm TCXO manufactured for us by Rakon utilising their

Pluto™ ASIC technology. Its wide frequency range, operating

temperature range and drive capability coupled with high

stability and linear frequency pulling make it the ideal

reference oscillator. Its ability to function down to a supply

voltage of 2.4V and low power consumption makes it suitable

for mobile applications

14.7 x 9.2mm

± 1ppm maximum in first year

± 3ppm maximum for 10 years

± 1ppm maximum after reflow

Optional reference voltage output on Pad 5, suitable for

potentiometer supply or DAC reference.

1. No output (Standard option)

2. 2.2V, for Min. Vs > 2.4V

3. 2.7V, for Min. Vs > 3.0V

4. 4.2V, for Min. Vs > 4.5V

Maximum load current (mA) = Vref/10

Frequency Adjustment

Three options with external Voltage Control applied to Pad 1:

For manual frequency adjustment (HCMOS/ACMOS output

only) connect an external 50kW potentiometer between Pad 5

(Reference Voltage) and Pad 3 (GND) with wiper connected to

Pad 1 (Voltage Control). Please specify reference voltage as a

part of the ordering code.

A - Ageing adjustment: > ± 5ppm (Standard Option)

B - No frequency adjustment. Initial calibration @ 25°C

< ± 0.5 ppm

C - High Pulling ±10ppm to ±50ppm may be available

depending on specification options. Contact our sales office

Linearity <1% (positive slope)

Input resistance >100k

Modulation bandwidth >2kHz

Standard control voltage ranges:

Without reference voltage - Vs = 5.0V 2.5V ± 2V

Without reference voltage - Vs = 3.3V 1.65V ± 1V

With reference voltage - Vc = 0V to Vref

–55 to 125°C

Logic ‘1’ (>60%Vs) to Pad 2 enables output

Logic ‘0’ (<20%Vs) to Pad 2 disables output

When at logic ‘0’ the output stage is disabled for all output

options, but the oscillator and compensation circuit are still

active (Current consumption < 1mA)

Standard 3.3V, 5.0V (see table)

Supply voltages in the range 2.4 to 6.0V available to order,

please contact our sales office

Note: Please contact our sales office if a reference voltage is

required in combination with sine or clipped sinewave output
