The DSC1203CI3-200M0000 is a 200 MHz LVDS MEMS oscillator in a 6-VDFN package — a direct-fit reference clock for SERDES, FPGA transceivers, and 10G Ethernet PHYs that need a low-jitter differential input. Supply voltage spans 2.5V to 3.3V, so the same part number works on either rail without a separate LDO or level translator — handy when the board has both 2.5V and 3.3V domains.

Frequently asked questions
Does the DSC1203CI3-200M0000 have a standby power-down function?
Yes — the function is listed as Standby (Power Down). When disabled, the supply current drops to 5 µA max, making it suitable for battery-backed designs that need to conserve power during sleep.
