The supply voltage range of 1.8V to 3.3V covers common logic rails; the CMOS output swings rail-to-rail, so no level translation is needed when feeding a 3.3V or 1.8V MCU clock input.
Product status is Active per Microchip's current lifecycle designation. Supplied in Tape & Reel (TR) packaging, 4-SMD no-lead footprint, 2.50 mm x 2.00 mm body.
This is the total variation including initial accuracy, temperature drift, and aging — no external trim capacitor is needed.
Yes, it replaces a quartz crystal plus its load capacitors and inverter — the MEMS XO integrates the resonator and oscillator circuit in one package. The CMOS output drives the clock input directly. Pin-compatible with standard 4-pin 2.5 x 2.0 mm XO footprints; verify the enable/disable logic on pin 1 matches your board.
Yes. The supply voltage range is 1.8V to 3.3V, and the CMOS output swings rail-to-rail. At 3.3V supply the output high level meets 3.3V CMOS thresholds without a level shifter.
