50 MHz LVPECL clock source with MEMS resonator
The DSC1122BE2-050.0000T is a 50 MHz MEMS-based oscillator from Microchip's DSC1122 series, delivering an LVPECL output that drives high-speed serial links, FPGA reference clocks, and 10GbE PHY reference inputs directly without an external level translator. Supply voltage spans 2.25V to 3.6V — the same part works across 2.5V and 3.3V rails, simplifying BOM consolidation when both voltage domains exist on the same board.

Housed in a 6-SMD no-lead package measuring 5.00mm × 3.20mm with a seated height of 0.90mm — the footprint is compatible with industry-standard 5.0×3.2 mm oscillator land patterns, so a board laid out for a quartz XO in the same form factor accepts this MEMS part without a layout change.
