CFPT-9000 SMD TCXO/TCVCXOs

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

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

▪*Dependent on frequency and output type

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.

Linearity: < 1%

▪

Slope: Positive

▪

Input resistance: > 100k

▪W

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

Storage Temperature Range

–55 to 125°C

▪

Tri-State Operation

Logic ‘1’ (>60%Vs) to Pad 8 enables output

▪

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)

Supply Voltage

Standard 3.3V, 5.0V ( see table)

▪

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

▪please contact our sales ofce

Supply Current

HCMOS Typically:

▪1+Frequency(MHz)*Supply(V)*{Load(pF)+15}*10–3 mA

e.g. 20MHz, 5V, 15pF ≈ 4mA

Sinewave <8mA

▪

Clipped Sinewave Typically:

▪1+Frequency(MHz)*1.2*{Load(pF)+30}*10–3mA

Ageing

±1ppm maximum in rst year, frequency <20MHz

▪

±2ppm maximum in rst year, frequency > 0MHz

▪

±3ppm maximum for 10 years (including the rst year),

▪frequency <20MHz

±5ppm maximum for 10 years (includng the rst year),

▪frequency >20MHz

After Reow

±1ppm max

▪

Reference Voltage, Vref

Optional reference voltage output on Pad 1, 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

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
