DS32KHZN/DIP – DALLAS

Overview

The Analog Devices Inc./Maxim Integrated DS32KHZN/DIP# is a high-precision Temperature Compensated Crystal Oscillator (TCXO) designed to deliver a stable 32.768 kHz output signal. Its core strength lies in its exceptional frequency stability of ±7.5ppm across a wide operating temperature range of -40°C to 85°C, crucial for applications where clock drift can lead to significant system errors. A key design consideration for TCXOs like this is the trade-off between temperature compensation complexity and power consumption; while offering superior accuracy, the active compensation circuitry contributes to a typical supply current of 220µA, which must be factored into power-budget-sensitive designs.
