12.95027

Overview

The Geyer Electronic America, Inc. 12.95027 is a ceramic surface-mount oscillator (XO) designed for frequency control applications. It operates at a nominal frequency of 50 MHz with a standard output tolerance of ±50 ppm. The device utilizes HCMOS logic levels and features a three-state output enable function, allowing for high-impedance states when disabled. It supports a supply voltage range from -0.5V to 7V and includes an internal load capacitance of 15 pF. The component is housed in a compact 4-pin SMD package without leads, suitable for automated assembly via tape and reel packaging.
