Quad-output MEMS clock in a single 5.0×3.2 mm package
The DSC400-4144Q0054KI1T is a MEMS-based XO that delivers four independent output frequencies from one 20-VFQFN package: 156.25 MHz on outputs 1 and 4, 100 MHz on output 2, and 50 MHz on output 3. Each output can be configured as HCSL or LVCMOS, making this a single-device clock source for PCIe reference clocks (100 MHz HCSL), Ethernet MAC/PHY (156.25 MHz LVCMOS), and lower-speed logic (50 MHz LVCMOS).
Frequency stability and supply tolerance for timing margin
The supply voltage range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails, with the MEMS resonator maintaining stability even as the rail droops under load.
