ABRACON ATXK-H11B 32.768kHz TCXO Oscillator

Introduction

The ABRACON ATXK-H11B-32.768KHZ-E50-T3 is a miniature temperature-compensated crystal oscillator (TCXO) designed to provide an accurate 32.768 kHz timing reference. Its low power consumption, wide operating-voltage range, and compact surface-mount package make it well suited to battery-powered and space-constrained electronic designs.

Part Description

This device is a 32.768 kHz TCXO with a CMOS output signal. Unlike a standard tuning-fork crystal, the oscillator integrates the circuitry required to generate a stable clock output, simplifying clock design and reducing the need for external oscillator components.

Key characteristics include:

• Frequency: 32.768 kHz
• Frequency stability: ±5 ppm
• Output type: CMOS
• Supply voltage range: 1.6 V to 5.5 V
• Operating temperature range: -40°C to +85°C
• Package size: 3.2 mm × 2.5 mm × 1 mm SMD
• Low-current operation: Suitable for low-power timing applications

The ±5 ppm stability helps maintain more accurate timekeeping across temperature changes than many conventional low-frequency crystal solutions.
