TXO012005-STO-5278

Oscillators Overview

The TXO012005-STO-5278 is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by Siward. It operates at a nominal frequency of 26 MHz and utilizes a clipped sine wave output signal. The device is designed for low-power applications, featuring a maximum supply current of 1.5 mA and an operating voltage of 1.2 V. Frequency stability is specified at ±500 ppb. The component is housed in a compact 4-SMD, no-lead package and supports tape-and-reel packaging. It functions within a temperature range of -30°C to 85°C.

Oscillators Feature Summary

• Built-in characteristic circuit compensates for temperature variations to maintain high frequency stability across wide operating ranges.
• Compact 4-SMD no-lead package design suitable for space-constrained surface-mount applications.
• Low power consumption profile with 1.2V operation and 1.5mA maximum supply current.

Oscillators Applications
