DS32KHZN/WBGA – MAXIM INTEGRATED

Overview

The Analog Devices Inc./Maxim Integrated DS32KHZN/WBGA is a highly stable 32.768 kHz Temperature Compensated Crystal Oscillator (TCXO) designed for applications demanding precise timekeeping. Its core strength lies in its ±7.5ppm frequency stability over a wide -40°C to 85°C operating range, crucial for maintaining synchronization in adverse environments. A key design consideration for TCXOs like this is the trade-off between stability and power consumption; while the DS32KHZN/WBGA offers excellent thermal compensation, engineers must carefully manage its 220µA maximum supply current to balance performance with battery life in portable systems.
