LFTVXO009916

Overview

The LFTVXO009916 is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 19.44 MHz with an HCMOS output format. The device requires a 3.3 V supply voltage and features a frequency stability of ±500 ppb. It is housed in an 8-SMD module package measuring 7.00 mm x 5.00 mm x 2.00 mm. The operational temperature range spans from -40°C to +85°C, supporting surface mount installation.

Feature Summary

Integrates voltage control and temperature compensation for enhanced frequency accuracy
Provides HCMOS digital output signal
Utilizes a compact 8-SMD surface mount package

Applications

Telecommunications equipment requiring precise clock synchronization
Industrial control systems needing stable timing references
Test and measurement instruments demanding low phase noise

Procurement Notes

Verify the specific ordering suffix and packaging configuration against the manufacturer's current datasheet before procurement. Confirm that the required frequency tolerance and control voltage range align with system specifications. Ensure compatibility with the target PCB footprint and thermal management requirements for the specified operating temperature range.

Selection Notes

Select this component when a balance of high stability and voltage tunability is required within a standard SMD form factor. Consider the ±500 ppb stability specification against application needs. Evaluate the 3.3 V supply constraint and HCMOS output drive capability relative to downstream circuitry requirements.

Part Context

This part belongs to the VCTCXO category from IQD Frequency Products, designed for applications requiring both temperature compensation and voltage-controlled frequency adjustment. It serves as a precision timing source where environmental variations may impact oscillator performance without active compensation mechanisms.
