The DSC1103DI1-400.0000 is an XO (Standard) MEMS oscillator delivering a 400 MHz LVDS output — a clean reference for SERDES, FPGA transceivers, or 10G Ethernet PHY clocking. Supply voltage spans 2.25V to 3.63V, making it compatible with both 2.5V and 3.3V logic rails without an external regulator.
Package footprint and board layout
Housed in a no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — the 0.098" x 0.079" footprint fits tight PCIe card or small-form-factor designs, but the six pads under the body mean the PCB land pattern must match the manufacturer's recommended layout for reliable solder joints.
