CFPT-9006

TCXO Specification

Electrical Parameters

3.3V ±10%

Supply Voltage

Supply Current:

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

e.g. 20MHz, 3.3V, 15pF ≈ 2mA

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

Maximum load current (mA) = Vref/10

For manual frequency adjustment connect an external 50kΩ

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.

Note: Supply Voltages in the range 2.4V to 6.0V are available,

please contact an IQD Sales Office

Frequency Adjustment

Slope: Positive

Standard Voltage Control Ranges:

Without Reference Voltage Vs=3.3V 1.65V±1.0V

With Reference Voltage Vs=0V to Vref

Linearity: 1% max

Input Impedance: 100kΩ min

Modulation Bandwidth: 2kHz min

A. Pulling:-

≥±5ppm, frequency ≤20MHz

≥±7ppm, frequency >20MHz

B. No frequency adjustment initial calibration @ 25°C ≤

±1.0ppm

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

depending on frequency and stability options (please contact

an IQD Sales Office)

Operating Temperature Ranges

0 to 50°C

-20 to 70°C

0 to 70°C

-30 to 75°C

-40 to 85°C

Output Details

Output Compatability

HCMOS

Drive Capability

15pF

Output Control

Tri-state Operation:

Logic ‘1’ (>60% Vs) or no connection 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)

Output Levels

VoL: <10% Vs

VoH: >90% Vs
