312.5 MHz LVPECL reference for high-speed serial links
The DSC1122AI2-312.5000T is a MEMS-based XO (standard) delivering a 312.5 MHz LVPECL output — a common reference clock for 10/25/40 GbE, Fibre Channel, and CPRI interfaces where the differential LVPECL swing drives the SERDES directly without AC-coupling or level translation.
Package, footprint, and board-level fit
Housed in a 6-SMD no-lead exposed pad package (7.00 mm x 5.00 mm x 0.90 mm max height), the DSC1122AI2-312.5000T shares the same footprint as standard 7x5 mm oscillators — a drop-in replacement for quartz-based LVPECL XOs in the same form factor.
