The DSC1203DI2-125M0000 is a MEMS-based XO delivering a 125 MHz LVDS clock with ±25 ppm frequency stability across -40°C to 85°C — a fit for Ethernet switch reference clocks, FPGA transceiver links, or any high-speed serial interface that needs a clean differential source. Supply voltage spans 2.25V to 3.63V, so it runs directly from a 2.5V or 3.3V rail without an intermediate regulator — one less BOM line for the power tree.
Standby power-down and package footprint
Housed in a 6-VDFN measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the package suits tight board stacks in optical modules or compact radio cards.
