Outputs are configurable as HCSL or LVPECL, so the same part drives PCIe reference clocks or high-speed SerDes without external translation. Operates from 2.25 V to 3.6 V — covers 2.5 V and 3.3 V rails commonly found on networking and FPGA boards. Housed in a 20-VFQFN with exposed pad, 5.00 mm x 3.20 mm body — the pad needs a thermal via array under the centre to pull heat into the ground plane. Height is 0.90 mm, which fits under a heatsink or enclosure lid in typical PCB stack-ups. Availability confirmed at RFQ.","metaTitle":"DSC400-4244Q0071KE1 MEMS XO – 161.132813 MHz, HCSL/LVPECL","metaDescription":"Microchip DSC400-4244Q0071KE1: MEMS XO, 4 outputs at 161.132813 MHz each, HCSL/LVPECL, 2.25-3.6V supply, ±50 ppm stability, -20 to 70°C.
