156.25 MHz LVPECL MEMS oscillator for high-speed clocking
The DSC1122CI5-156.2500T is a MEMS-based XO (Standard) oscillator delivering a 156.25 MHz LVPECL output — a common reference for 10 Gigabit Ethernet, Fibre Channel, and high-speed serial links where the LVPECL swing provides the noise margin needed over long board traces. Supply voltage spans 2.25 V to 3.6 V, so the same BOM line serves both 2.5 V and 3.3 V clock domains without a level translator on the oscillator power pin.
The MEMS resonator construction eliminates the quartz crystal's cold-start and vibration sensitivity issues, making this oscillator a drop-in for designs that need a reliable 156.25 MHz reference in industrial or outdoor equipment.
6-SMD package and Enable/Disable function
Housed in a 3.20 mm x 2.50 mm 6-SMD no-lead package, the oscillator fits tight board layouts; the Enable/Disable pin lets the system power down the output to 22 mA max supply current during sleep modes.
