The part ships in Tape & Reel (TR) packaging, no-lead exposed-pad footprint (7.00 mm x 5.00 mm x 0.90 mm). ## Design-in note: standby function and the enable pin The standby (power-down) function is the key feature that distinguishes this oscillator from simpler fixed-output XOs. The output goes high-impedance — the downstream load sees a floating clock line, so the receiving device must handle a clock-loss condition gracefully or have a pull-down on the clock input. The ±25 ppm stability is specified at 3.3 V ±10% — keep the supply rail within that tolerance across the load range to avoid frequency drift.","metaTitle":"DSC1033AI2-008.0000T MEMS XO, 8 MHz, CMOS","metaDescription":"DSC1033AI2-008.0000T is a Microchip PureSilicon™ MEMS oscillator, 8 MHz, CMOS output, ±25 ppm, 3.3 V, standby function.

The DSC1033 series includes other frequency and stability variants, but no single order code is listed as a drop-in replacement. For a new design, consider the active DSC1001 or DSC1121 families from Microchip, which offer similar MEMS-based performance in the same 4-SMD footprint with standby capability. Confirm pinout and enable polarity before committing."},{"question":"Where can I find the datasheet for the DSC1033AI2-008.0000T?","answer":"The datasheet for the DSC1033AI2-008.0000T is available from Microchip's website under the DSC1033 series product page. The part number is listed under the PureSilicon™ MEMS oscillator family. The datasheet covers the full parametric table including frequency stability vs. temperature, supply current vs. load, and the standby function timing diagram."},{"question":"What is the standby function on the DSC1033AI2-008.0000T?","answer":"The standby (power-down) function shuts down the MEMS resonator and output driver when the enable pin is pulled low. The supply current drops from 3 mA typ to 1 µA max, and the output goes high-impedance. This is useful for battery-operated systems that need to disable the clock between active periods."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033AI2-008.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033AI2-008.0000T when reusing this data.
