Active production — 100 MHz HCSL clock source
The DSC1224NL3-100M0000T is an active-production XO (Standard) from Microchip's DSC1224 series, delivering a fixed 100 MHz output in HCSL logic levels. HCSL (High-Speed Current Steering Logic) is the differential clock format used in PCIe reference clocks, 10GbE MAC/PHY interfaces, and FPGA transceiver banks. The 100 MHz frequency lands directly on the reference clock input of many PCIe Gen 1/2/3 root complexes and switch chips — the output swing and common-mode voltage match the HCSL receiver threshold without external level translation.
Supply flexibility and disable function
The supply voltage range spans 2.5V to 3.3V, so the oscillator runs from either a 2.5V or 3.3V rail without a separate regulator.
Industrial temperature grade and 6-VDFN package
The 6-VDFN package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight board areas, though the 0.50 mm pitch pads require careful solder-paste stencil design to avoid bridging.
No official second-source or pin-compatible cross is listed; the MEMS resonator and HCSL output are specific to this Microchip family.
