Overview

The LFTVXO085759 is a high-precision 10 MHz Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) from IQD Frequency Products. This 3.3V HCMOS oscillator provides exceptional frequency stability of +/-280ppb across a wide operating temperature range of -40 to 105 degrees Celsius. It features an amplitude control function, allowing for fine-tuning of the output frequency via an external voltage.

Why Choose This Part

This VCTCXO offers a high frequency stability of +/-280ppb, ensuring minimal drift in demanding thermal environments. The 7.00mm x 5.00mm 4-SMD package is standard for high-reliability industrial applications, and the extended operating temperature range up to 105 degrees Celsius makes it suitable for outdoor or high-heat deployments.

Applications

Precision Timing Reference
Serves as a stable master clock for industrial communication protocols and synchronization tasks.
GPS/GNSS Receivers
Provides the high-stability reference required for rapid signal acquisition and accurate positioning in satellite navigation systems.
Wireless Base Stations
Used in RF infrastructure where tight frequency control is necessary to maintain channel spacing.
Test and Measurement Equipment
Acts as an internal frequency standard for portable diagnostic and instrumentation hardware.

Getting Started

To integrate this part, ensure the 3.3V supply is well-filtered to prevent noise from affecting frequency stability. Use a high-impedance control voltage source for frequency adjustment and follow standard reflow soldering profiles for the 4-SMD ceramic package. Prototyping can be done on custom carrier boards or by using a dedicated oscillator test fixture to verify the +/-280ppb stability before PCB integration.

Also Consider

CVHD-950 Crystek Corporation - Consider this if ultra-low phase noise is prioritized over the VCTCXO temperature compensation stability.
