Description
The HC-49SMD 12.288 MHz is a precision quartz crystal designed for high-performance timing applications. The frequency 12.288 MHz is a vital “audio-grade” frequency, frequently utilized in digital audio processing because it is a direct multiple of standard sampling rates (such as 32 kHz, 44.1 kHz, and 48 kHz). This makes it the preferred clock source for ADCs, DACs, and digital signal processors in professional audio equipment.
Packaged in the reliable, low-profile HC-49SMD metal case, this crystal offers excellent mechanical stability and protection against environmental interference. With a load capacitance of 20 pF and a tight frequency tolerance of ±20 ppm, it provides the low-jitter reference necessary to minimize clock-induced distortion in audio streams. This pack includes two units, perfect for prototyping or dual-channel audio systems.
