Four fixed clocks from a single MEMS resonator
The DSC400-4134Q0050KE1T: This XO generates four independent output frequencies from a single MEMS resonator: 100 MHz on outputs 1 and 4, 125 MHz on output 2, and 50 MHz on output 3. Each output can be configured as HCSL, LVCMOS, or LVDS, letting one device feed a mixed-signal board with a PCIe reference, a SerDes clock, and a logic-level system clock.
Operates from 2.25 V to 3.6 V, covering the common 2.5 V and 3.3 V FPGA/SoC rails without an external regulator.
