The DSC1121BI2-012.2880 is a MEMS-based XO (Standard) oscillator delivering a 12.288 MHz CMOS output — a common reference frequency for Ethernet PHYs, T1/ framing, and baseband processors.
The supply range spans 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without an intermediate regulator — one BOM line serves either rail.
Sourced through independent distribution; confirmed availability and pricing at RFQ.
Within the DSC1121 series, any oscillator with the same 6-SMD no-lead package and supply voltage range is pin-compatible. The frequency is the differentiating parameter — no direct equivalent at 12.288 MHz is listed, but the family shares the same footprint and control logic.
