MEMS oscillator at 12.288 MHz — active production
The DSC1030BI1-012.2880T is a MEMS-based XO delivering a 12.288 MHz CMOS output from a 3V supply rail. The 12.288 MHz frequency is a common multiple for Ethernet PHY reference clocks and audio sample-rate generators.
The typical supply current is 3 mA (max) — low enough for a 24/7 powered Ethernet switch port or a battery-backed sensor node that clocks a UART at 115200 baud.
Package and footprint — 5.0 × 3.2 mm 4-SMD
Housed in a 4-SMD No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm. The 0.197 × 0.126 inch footprint is a standard industry size shared by many quartz and MEMS oscillators — the land pattern matches the common 5.0 × 3.2 mm oscillator pad layout, so a board designed for a quartz XO in this form factor can accept the DSC1030BI1-012.2880T without a PCB spin.
