Overview

The AST3TQ-T-10.000MHZ-50-C is a high-precision Temperature Compensated Crystal Oscillator (TCXO) designed for applications requiring exceptional frequency stability of +/-50ppb. Operating at 10 MHz with a 3.3V supply, this LVCMOS output oscillator provides a reliable reference clock across a wide industrial temperature range of -40C to +85C. Its compact 7.00mm x 5.00mm surface-mount package makes it suitable for space-constrained high-performance electronics.

Why Choose This Part

This TCXO offers ultra-tight frequency stability of +/-50ppb, which is significantly better than standard oscillators, reducing the need for frequent recalibration. The LVCMOS output ensures compatibility with most modern FPGAs and microcontrollers without requiring complex interface circuitry. Its rugged 4-SMD package is optimized for automated pick-and-place assembly while maintaining performance under thermal stress.

Applications

Base Station Timing
Provides the stable reference clock necessary for synchronization in small cells and telecommunications infrastructure.
GPS and GNSS Receivers
Used as a master clock for satellite positioning systems where rapid signal acquisition depends on frequency accuracy.
Test and Measurement Equipment
Serves as a high-stability internal timebase for portable frequency counters and handheld analyzers.
Network Switches and Routers
Ensures precise timing for high-speed data packet switching and industrial Ethernet synchronization.

Getting Started

To integrate this component, ensure a 0.1uF bypass capacitor is placed as close as possible to the VCC pin (Pin 4) to minimize noise. Trace lengths for the 10 MHz LVCMOS output should be kept short and impedance-matched to 50 ohms if traveling significant distances to prevent signal reflections. Evaluation can be performed by soldering the 7x5mm footprint onto a breakout board and connecting it to a regulated 3.3V DC source.
