The DSC1001CI2-028.6363 is a MEMS-based XO (Standard) oscillator delivering a 28.6363 MHz CMOS output with ±25 ppm frequency stability. The MEMS resonator eliminates quartz aging drift and start-up reliability issues common in crystal oscillators — it is a drop-in replacement for quartz-based XOs in the same footprint. Supply voltage spans 1.8V to 3.3V, so the same oscillator serves 1.8V MCU cores, 2.5V FPGA banks, and 3.3V peripheral buses without a level translator on the clock line.
Standby power-down and current draw
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.50 mm pitch and no-lead design mean the PCB footprint is identical to standard quartz XOs in the same 3.2x2.5 mm package — no layout change needed when swapping from quartz to MEMS.
