156.25 MHz LVPECL clock source for high-speed serial links
The DSC1122BI2-156.2500 is a MEMS-based XO (Standard) oscillator delivering a 156.25 MHz LVPECL output — a common reference frequency for 10 Gigabit Ethernet, Fibre Channel, and other high-speed SerDes applications where the differential LVPECL swing provides the edge rates and noise margin the PHY or FPGA expects.
Package footprint and layout compatibility
Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — this is the industry-standard 5.0 x 3.2 mm oscillator footprint that matches many quartz crystal oscillator drop-in replacements, so a board laid out for a 5.0 x 3.2 mm crystal oscillator can often accept this MEMS part without a layout change.
