YSX321SL 22.1184 MHz 20pF ±10ppm 4-Pin SMD Metal Surface Quartz Crystal (Pack of 2)

Description

The YSX321SL 22.1184 MHz is a high-precision, 4-pin surface-mount quartz crystal optimized for communication and microcontroller timing. Similar to the 14.7456 MHz crystal, the 22.1184 MHz frequency is widely favored in embedded systems design as a “baud-rate friendly” crystal. It allows microcontrollers to generate standard UART baud rates (such as 9600, 19200, 38400, or 115200 bps) with virtually zero percentage error, ensuring robust and reliable serial data communication.

Housed in a durable metal-surface SMD package, the YSX321SL is engineered for modern, high-density PCB layouts and automated surface-mount assembly. With a load capacitance of 20 pF and a tight frequency tolerance of ±10 ppm, it provides the stable, clean clock signal required for high-speed digital processing and peripheral synchronization. This package includes two units, offering excellent value for prototyping and production requirements.
