The DSC1122BI1-125.0000T is a MEMS-based XO (Standard) delivering a 125 MHz LVPECL output from a 2.25V to 3.6V supply rail — a drop-in replacement for quartz oscillators in the same 6-SMD footprint, with the MEMS resonator's inherent immunity to vibration and faster start-up.
This part is Active and in production. Submit an RFQ with your target quantity and lead-time window; we source through independent distribution and confirm availability and pricing per order.
Yes — the 6-SMD no-lead footprint and 2.25-3.6V supply are compatible with most quartz XO layouts. The MEMS resonator offers faster start-up and better vibration resistance, though the LVPECL output requires a 50-ohm terminated line, unlike CMOS quartz oscillators.
