Package and board-fit details
The DSC6122CE1A-0057: The CMOS output is compatible with most digital logic families without needing a level translator, simplifying the BOM. Frequency stability is rated at ±50 ppm, which is adequate for general-purpose clocking (UART, SPI, low-speed MCU clocks) but not tight enough for precision timing like Ethernet or high-speed serial interfaces that typically demand ±25 ppm or better.
