Overview

The AST3TQ53-T-10.000MHZ-5-C is a high-precision Temperature Compensated Crystal Oscillator (TCXO) from Abracon, designed for applications requiring exceptional frequency stability. It provides a stable 10 MHz LVCMOS output with a frequency stability of plus or minus 50ppb across its full operating temperature range of -40 to 85 degrees Celsius. This surface-mount component is optimized for low power consumption, drawing a maximum current of 6mA at a 3.3V supply voltage.

Why Choose This Part

This TCXO offers ultra-tight stability of 50ppb in a compact 5.0mm x 3.2mm footprint, making it suitable for space-constrained designs. Its low 6mA current draw and 3.3V operation support energy-efficient system designs without sacrificing clock precision.

Applications

Precision Timing References
Used as a master clock in communication systems where high frequency stability is critical for data synchronization.
Wireless Infrastructure
Ideal for base stations and small cells requiring tight frequency tolerances to maintain network timing integrity.
Measurement Instrumentation
Provides a reliable timebase for portable test equipment and data acquisition systems operating in varied thermal environments.
