The OX-5021-EAE-1080-20M000 by Microchip is a high-precision Oven Controlled Crystal Oscillator (OCXO) designed for use in demanding applications that require stable and accurate frequency sources. This OCXO features a compact surface-mount device (SMD) design measuring 14.3 x 9.4 x 6.1mm, making it suitable for space-constrained applications. Powered by a 3.3V supply, it operates within a wide temperature range of -40 to +85°C, ensuring consistent performance under varying environmental conditions. The OX-5021-EAE-1080-20M000 offers an exceptional frequency stability of +/-10 parts per billion (ppb) at 20MHz, attributed to its oven-controlled design which minimizes frequency variations due to temperature changes. This level of precision makes it ideal for use in telecommunications, satellite communications, precision instrumentation, and synchronization systems where accurate timing and synchronization are critical. The HCMOS output enables easy integration into digital systems. As a testament to Microchip's commitment to quality and reliability, this OCXO provides engineers with a reliable frequency source for their high-performance designs.
