Overview

The LFTVXO085766 is a high-precision 38.88 MHz Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) from IQD Frequency Products. It features a high frequency stability of +/-50ppb and operates across an extended temperature range of -40 to 105 degrees Celsius, making it suitable for demanding timing applications.

Why Choose This Part

This oscillator offers an exceptional stability-to-size ratio in a compact 7mm x 5mm 4-SMD package. With a low 10mA maximum current draw at 3.3V and an Absolute Pull Range (APR) of +/-5ppm, it balances power efficiency with the flexibility of frequency adjustment.

Applications

Synchronous Ethernet (SyncE)
Provides the precise 38.88 MHz reference clock required for network synchronization in high-speed telecommunications infrastructure.
Wireless Base Stations
Used as a stable local oscillator reference in cellular infrastructure where thermal drift must be minimized.
Industrial IoT Gateways
Reliable timing source for communication modules operating in harsh outdoor environments with wide temperature fluctuations.
Point-to-Point Microwave Links
Maintains signal integrity in RF backhaul equipment through its low frequency tolerance and integrated voltage control for fine-tuning.

Getting Started

When integrating this VCTCXO, ensure the 3.3V supply is decoupled with a 0.1uF ceramic capacitor placed as close as possible to the Vcc pin. The HCMOS output should be routed with controlled impedance to avoid signal reflections, and the frequency control pin requires a low-noise voltage source for precise tuning.
