That puts it into engine-adjacent or cabin electronics — ECU, BCM, infotainment — where a crystal oscillator's mechanical fragility is a concern. That is a 480× reduction. The pin controlling the standby mode is typically a dedicated enable pin on the DSC1001. Pull it low to disable the output; the MEMS resonator itself may keep running internally, but the output driver is off, so the downstream logic sees a high-impedance state. That covers 1.8V MCU I/O banks, 2.5V FPGA banks, and 3.3V peripheral rails. The 4-SMD, no-lead package is 3.20 mm × 2.50 mm with a 0.90 mm seated height — small enough for space-constrained automotive modules. No level translation needed as long as the receiving logic's supply matches the oscillator's Vdd. There is no last-time-buy deadline or NRND flag on this order code.","metaTitle":"DSC1001CI2-035.4689T – Microchip MEMS XO, 35.4689 MHz, CMOS","metaDescription":"Microchip DSC1001CI2-035.4689T: MEMS XO, 35.4689 MHz, CMOS, ±25 ppm stability, 1.8-3.3V, AEC-Q100, -40 to 85°C, standby function.","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":"DSC1001","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"35.4689 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"7.2mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the standby function on the DSC1001CI2-035.4689T?","answer":"The standby (power-down) function disables the output driver, dropping the supply current from a maximum of 7.2 mA to just 15 µA.
