156.25 MHz LVDS clock source for high-speed links
The DSC1123BI5-156.2500 is a MEMS-based XO (Standard) oscillator delivering a 156.25 MHz LVDS output — a common reference frequency for 10 Gigabit Ethernet, Fibre Channel, and PCI Express Gen 1/2 clocking. The LVDS differential pair keeps jitter low over board traces, which matters when the clock edge drives a SerDes PLL that multiplies up to line rate.
Stability and supply range for industrial environments
The 2.25V to 3.63V supply range lets it run from a 2.5V or 3.3V rail without an external LDO; the 32 mA max supply current is the total draw including the LVDS output stage.
