CFPT-9000 SMD TCXO/TCVCXOs

ISSUE 12; 1 NOVEMBER 2008 - RoHS 2002/95/EC

Supply Voltage

▪

Description

Sub 1ppm performance TCXO manufactured for us by

Rakon utilising their Pluto™ ASIC technology, a single chip

oscillator and analogue compensation circuit operating over

an extended temperature range. Its ability to function down to

a supply voltage of 2.4V and low power consumption make it

particularly suitable for mobile applications

Frequency Adjustment

Three options with external Voltage Control applied to Pad 10:

▪

A - Ageing adjustment: > ±5ppm, frequency < 20MHz

(Standard Option)

> ±7ppm, frequency > 20MHz

B - No frequency adjustment initial calibration @ 25°C

< ±1.0 ppm

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

depending on frequency and stability options.

Please consult our sales office

Linearity: < 1%

Slope: Positive

Input resistance: > 100k

Modulation bandwidth: > 2kHz

Standard voltage control ranges:

Without reference voltage - Vs=5.0V 2.5V±1V

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 8 enables output

For manual frequency adjustment connect an external 50kW

potentiometer between Pad 1 (Reference Voltage) and Pad 4

(GND) with wiper connected to Pad 10 (Voltage Control). Please

specify reference voltage as part of the ordering code

Tri-State Operation

Logic ‘0’ (<20%Vs) to Pad 8 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)
