The DSC1124CI5-100.0000: HCSL (High-Speed Current Steering Logic) is the reference clock format specified for PCIe, SATA, and many FPGA transceiver banks — this oscillator drives the differential clock pair directly, no external level translation needed. Supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V rails without a separate regulator — the Enable/Disable function lets the system gate the clock during low-power sleep modes.
The MEMS resonator construction eliminates the quartz crystal aging and shock sensitivity issues that drive obsolescence in traditional oscillators — the DSC1124 series has been a stable production line for years.
Package, supply, and board-fit checklist
6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — this is the standard 3.2x2.5 mm footprint shared across many MEMS and quartz oscillators, so the PCB land pattern is well established.
