Overview

The LFTCXO063709 is a high-precision Temperature Compensated Crystal Oscillator (TCXO) from IQD's IQXT-200 series. Operating at 10.0MHz with a 3.3V supply, it provides a stable HCMOS output with a tight frequency stability of +/-0.28ppm over a temperature range of -20 to 70C. This component is housed in a standard 7.0 x 5.0mm 4-pad surface mount package.

Why Choose This Part

This oscillator offers superior frequency stability of +/-0.28ppm, significantly outperforming standard crystal oscillators in varying thermal environments. Its 7.0 x 5.0mm footprint is an industry standard, facilitating easy integration into existing PCB layouts without specialized mounting requirements.

Applications

GPS and GNSS Receivers
Provides the stable reference clock required for rapid satellite signal acquisition and reliable positioning data.
Base Stations and Femtocells
Acts as a local timing source for wireless infrastructure where synchronization is critical for network handovers.
Point-to-Point Communication
Ensures frequency accuracy in microwave and radio links to prevent data throughput degradation due to clock drift.
Precision Test Instrumentation
Serves as a cost-effective alternative to OCXOs in portable measurement tools requiring sub-1ppm stability.

Getting Started

To implement this TCXO, ensure a 10nF to 100nF decoupling capacitor is placed as close as possible to the VCC pin. The HCMOS output is designed to drive standard logic loads, but trace lengths should be minimized to maintain signal integrity and reduce EMI. Frequency can be verified using a calibrated frequency counter or by probing the clock input of the target microcontroller or FPGA.
