MEMS-based quad-output clock source
The DSC400-2222Q0022KE2 is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering four independent LVPECL outputs from a single 5.00 mm x 3.20 mm, 20-VFQFN package. Output frequencies are 125 MHz, 100 MHz, 100 MHz, and 125 MHz, with ±25 ppm stability across -20°C to 70°C.
LVPECL output and supply tolerance
LVPECL outputs are the differential standard for driving clock trees into FPGAs, high-speed ADCs, and SerDes transceivers. The 2.25 V to 3.6 V supply range covers 2.5 V and 3.3 V rails without an external regulator — useful when the board has mixed logic supplies.
Package and layout consideration
Microchip lists the DSC400-2222Q0022KE2 as Active.
