100 MHz HCSL MEMS oscillator for timing-critical boards
The DSC1124BI5-100.0000 is a 100 MHz XO (Standard) from Microchip's DSC1124 series, built on a MEMS resonator rather than a quartz crystal. It delivers an HCSL output — the differential current-mode logic common in PCIe reference clocks and high-speed SerDes — across a supply range of 2.25 V to 3.6 V.
Enable/Disable pin and power budget
Maximum supply current when enabled is 42 mA; with the output disabled it drops to 22 mA — useful for power-gating clock trees in battery-backed line cards or fan-out buffers.
Package, footprint, and layout fit
Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The pad layout matches the industry-standard 5.0 x 3.2 mm quartz oscillator footprint — no board spin needed when replacing a quartz XO with this MEMS part.
