MEMS XO at 16.384 MHz — CMOS output, ±10 ppm
The DSC1101NI5-016.3840T is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a 16.384 MHz CMOS output with ±10 ppm frequency stability. The MEMS resonator eliminates the quartz-crystal start-up time and vibration sensitivity typical of conventional oscillators — the output is valid within microseconds of power-up, which matters for a processor clock that must be stable before the PLL locks.
Industrial temperature range, wide supply tolerance
The supply voltage spans 2.25V to 3.6V — a single 3.3V rail or a 2.5V core supply both work without an external regulator; the CMOS output swings rail-to-rail, so the logic threshold tracks the supply.
