159.375 MHz LVPECL clock source for high-speed serial links
The DSC1122AI1-159.3750 is a MEMS-based XO (Standard) oscillator delivering a 159.375 MHz LVPECL output — a frequency commonly used as a reference clock for 10 Gigabit Ethernet PHYs, FPGA transceivers, and SerDes blocks that require a low-jitter differential input.
Supply voltage tolerance and temperature range
Operating from 2.25 V to 3.63 V, the oscillator covers both 2.5 V and 3.3 V rails with headroom for rail droop — no separate regulator needed when the supply is within that window.
