It delivers a 12.288 MHz CMOS output, a common frequency for Ethernet PHY reference clocks, audio sample-rate generators, and FPGA configuration oscillators. ## Supply voltage flexibility and output control The supply voltage accepts 2.25V to 3.6V — a single part number works on 2.5V or 3.3V rails, simplifying BOM consolidation across mixed-voltage boards. An Enable/Disable pin lets the system tri-state the output for power sequencing or test access while keeping the oscillator core powered — no external load switch needed. Maximum supply current is 35 mA, which includes the MEMS drive and CMOS output buffer; the actual draw depends on the output load capacitance and frequency. ## Package, footprint, and board integration Housed in a 6-VDFN package with an exposed pad (7.00 mm x 5.00 mm, 0.90 mm seated height), the thermal pad should be soldered to a ground plane for heat sinking and mechanical stability. Surface-mount assembly; the exposed pad requires a solder stencil aperture matched to the datasheet land pattern to avoid voids or tombstoning. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1121AM1-012.2880 MEMS XO 12.288 MHz CMOS -55°C to 125°C","metaDescription":"DSC1121AM1-012.2880: Microchip MEMS XO, 12.288 MHz, CMOS output, 2.25V-3.6V supply, Enable/Disable, -55°C to +125°C, 6-VDFN.
