100 MHz HCSL clock with MEMS resonator
The DSC1224BL2-100M0000 is a 100 MHz XO (Standard) with HCSL output — the differential current-mode logic used for PCIe reference clocks and high-speed serial links. The MEMS resonator replaces a quartz crystal, giving better shock and vibration tolerance and typically faster factory lead times than a quartz-based equivalent. Supply voltage covers 2.5V to 3.3V, so it runs from a common 3.3V or 2.5V rail without a separate regulator. Enable/Disable function lets the system shut down the oscillator when the link is idle, saving the 23 mA typical disable current.
Active lifecycle — no end-of-life risk
This part is suitable for new designs and production builds without last-time-buy planning. Microchip continues to manufacture the DSC1224 series.
Rated -40°C to 105°C — the extended industrial band covers outdoor telecom cabinets, engine-bay electronics, and factory-floor equipment. The 6-VDFN package measures 5.00mm x 3.20mm with a seated height of 0.90mm, fitting dense PCB layouts where height is constrained.
