Overview

The LFTVXO085760 is a high-precision 19.2 MHz Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) from IQD Frequency Products. It offers exceptional frequency stability of +/-50ppb and is designed for applications requiring a stable reference clock over a wide temperature range of -40C to 105C. The device operates at 3.3V and features an HCMOS output with amplitude control for fine frequency tuning.

Why Choose This Part

The primary advantage is the ultra-tight stability of +/-50ppb, which is significantly better than standard TCXOs. It maintains this performance across an extended industrial temperature range up to 105C, making it suitable for thermally demanding enclosures. The 7.0mm x 5.0mm footprint provides a stable physical platform for high-reliability surface mount assembly.

Applications

GPS and GNSS Receivers
Provides the high-stability reference clock necessary for rapid satellite signal acquisition and precise positioning.
Base Station Synchronization
Used in cellular infrastructure and small cells to maintain tight timing synchronization between network nodes.
Emergency Radio Equipment
Ensures reliable frequency control in mission-critical handheld radios and communication terminals.
IoT Gateways
Acts as a primary clock source for long-range wireless gateways requiring low frequency drift in outdoor environments.

Getting Started

When integrating this VCTCXO, ensure a clean 3.3V supply with local decoupling capacitors to minimize phase noise. Design the PCB layout with a dedicated ground plane under the oscillator and keep high-speed digital traces away from the frequency control and output pins. The voltage control pin allows for frequency pulling, which can be driven by a precision DAC or a filtered PWM signal for system-level synchronization.
