LFTVXO009920

Overview

The LFTVXO009920 is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with an HCMOS output waveform. The device is powered by a 3.3 V supply and draws a maximum current of 3 mA. It features a frequency stability of ±500 ppb and functions within a temperature range of -40°C to +85°C. The component utilizes an 8-SMD surface-mount package measuring 7.00 mm in length, 5.00 mm in width, and 2.00 mm in height.

Feature Summary

• Integrates voltage control and temperature compensation for high frequency stability
• Provides square wave output via HCMOS interface
• Utilizes ceramic packaging with hermetically sealed metal lid

Applications

• Communication systems requiring precise timing
• Industrial equipment needing stable clock signals
• Medical devices demanding reliable oscillator performance

Procurement Notes

Verify the specific ordering suffix and packaging configuration against official IQD documentation before procurement. Confirm that the required frequency tolerance and voltage control range align with system specifications. Ensure the operating temperature range meets environmental requirements. Cross-reference the pinout and electrical characteristics with the latest datasheet to prevent integration errors during design implementation.

Selection Notes

Select this component when a compact surface-mount solution is required for applications needing both voltage tuning and thermal stability. The 8-SMD form factor suits space-constrained designs. Verify that the 3.3 V supply voltage matches the target circuit logic levels. Consider the ±500 ppb stability requirement against the specific phase noise and jitter needs of the application to ensure adequate signal integrity.

Part Context

This part belongs to the CFPT-126 series of controlled oscillators from IQD Frequency Products. It represents a specialized category of frequency generation components designed for environments where standard crystal oscillators lack sufficient stability across varying temperatures. The series integrates compensation circuits directly into the package to maintain accuracy without external calibration.
