It runs from a single 3.3 V supply and draws 10 mA max while active; in standby (power-down) mode the supply current drops to 1 µA max, making it suitable for battery-powered equipment that needs to gate the clock tree. Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint for space-constrained PCBs.","metaTitle":"DSC1033DI2-007.3728 MEMS Oscillator – Microchip, 7.3728 MHz","metaDescription":"DSC1033DI2-007.3728 from Microchip: MEMS XO, 7.3728 MHz, CMOS output, ±25 ppm, -40°C to 85°C, 3.3 V, 4-SMD.

The DSC1033DI2-007.3728 is a drop-in MEMS replacement in a 4-SMD no-lead package — no external load capacitors are required. Confirm the footprint matches the 2.50 mm x 2.00 mm outline and the enable/standby pin function aligns with your circuit."},{"question":"Does DSC1033DI2-007.3728 require external capacitors?","answer":"No. Because it is a MEMS oscillator (XO) with an integrated resonator and CMOS output stage, it does not need the load capacitors that a bare quartz crystal would require. Connect the supply, ground, and output — the standby pin can be tied high or driven by a GPIO to enable the output."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033DI2-007.3728","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033DI2-007.3728 when reusing this data.
