Both outputs are configurable as LVCMOS or LVDS, giving the designer a single oscillator to drive a video clock and a serial/peripheral clock on the same device. Frequency stability is rated at ±50 ppm over the -20 to 70 °C commercial temperature range, and the supply voltage accepts 2.25 V to 3.6 V — a wide-enough window to run from a 2.5 V or 3.3 V rail without an external LDO. Housed in a 20-VFQFN with exposed pad, measuring 5.00 mm x 3.20 mm and standing 0.90 mm tall, the DSC400-0103Q0102KE1T fits a standard QFN footprint. The exposed pad must be soldered to a thermal via array on the PCB — the datasheet's recommended land pattern (page 7) specifies a 3.2 mm x 2.2 mm pad with a 0.3 mm via grid for adequate heat transfer.","metaTitle":"DSC400-0103Q0102KE1T MEMS XO – 148.5 MHz / 14.7456 MHz","metaDescription":"Microchip DSC400-0103Q0102KE1T: dual-output MEMS XO, 148.5 MHz + 14.7456 MHz, LVCMOS/LVDS, ±50 ppm, 2.25-3.6 V, -20 to 70 °C, 20-VFQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Height":"0.035\\\" (0.90mm)","Output":"LVCMOS, LVDS","Series":"DSC400","Package":"Tape & Reel (TR)","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC400","Frequency Stability":"±50ppm","Frequency - Output 1":"148.5MHz","Frequency - Output 2":"14.7456MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/35fee811e2c5afa73b9fd9ee5f104fbf.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the frequency stability of the DSC400-0103Q0102KE1T?","answer":"Frequency stability is ±50 ppm over the -20 to 70 °C operating range.
