It replaces quartz crystal oscillators in applications where shock, vibration, or temperature extremes would cause a quartz resonator to drift or fail. The MEMS resonator is the timing element — no quartz blank, no crystal aging curve to track. Startup time is typically under 5 ms, versus tens of milliseconds for a quartz oscillator, so the clock is stable before the MCU releases reset. The Enable/Disable function lets the system gate the output without cycling power — useful for clock gating in low-power sleep modes where the oscillator stays biased but the load is disconnected. It belongs in avionics black boxes, satellite payloads, downhole drilling tools, and engine-bay electronics where a commercial-grade oscillator would fail from thermal stress. Frequency stability is ±25 ppm across the full temperature range — tight enough for a 16 MHz MCU clock or a CAN bus node without needing a TCXO. ## Supply voltage and power budget Operates from 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external LDO. Maximum supply current is 35 mA — the MEMS core draws less than a quartz oscillator at the same frequency, leaving headroom for the rest of the rail. ## Package and board layout Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The small footprint saves board space compared to a 5x7 mm quartz oscillator, but the VDFN land pattern requires careful solder-paste stencil design to avoid bridging on the centre pad. Surface-mount only — no through-hole variant. The DSC1121 series is a current production family, so new designs can commit to this part without worrying about a near-term obsolescence. Sourced to order through independent distribution.","metaTitle":"DSC1121DM2-016.6400T MEMS Oscillator","metaDescription":"Active Microchip DSC1121DM2-016.6400T XO (Standard) MEMS oscillator, 16.64 MHz CMOS output, -55°C to 125°C, 2.25V-3.6V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"16.64 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-55°C~125°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the exact output frequency of DSC1121DM2-016.6400T?","answer":"16.64 MHz, CMOS output."},{"question":"Can DSC1121DM2-016.6400T replace a standard quartz oscillator?","answer":"Yes, it is a drop-in replacement for a 16.64 MHz quartz oscillator in the same 6-VDFN footprint, with better shock and vibration tolerance and faster startup.
