Housed in a 14-VFQFN Exposed Pad package measuring 3.20 mm x 2.50 mm with a 0.90 mm profile, it fits tight board stacks where a single oscillator replaces two cans. Expect it in outdoor telecom cabinets, factory-floor PLCs, and engine-bay control modules where ambient heat cycles are the norm. ## Current consumption and disable mode Maximum supply current is 76 mA typical when both outputs are active — the dual-frequency architecture draws about what a single high-speed XO would, thanks to the MEMS resonator core. That is the quiescent draw of the internal bias circuits; the outputs are tri-stated, so the downstream logic sees no clock edge. Supplied in Tape & Reel (TR) from Microchip.","metaTitle":"DSC2042FI2-M0005T MEMS XO – 156.25 MHz & 25 MHz, HCSL/LVPECL","metaDescription":"Active Microchip MEMS XO, dual output 156.25 MHz & 25 MHz, HCSL/LVPECL, ±25 ppm, -40°C to 85°C, 14-VFQFN.

The MEMS resonator is more shock and vibration tolerant than quartz, but the output logic (HCSL or LVPECL) must match the receiver. Verify the load termination: LVPECL needs a DC bias network; HCSL typically uses a 50-ohm pull-up to VDD."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC2042FI2-M0005T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC2042FI2-M0005T when reusing this data.
