The typical supply current is 4 mA at 3.3 V, and when the standby pin is asserted the oscillator drops to 1 µA. For a battery-powered design that sleeps most of the time, that standby current is essentially the leakage floor of the PCB. This oscillator is intended for indoor electronics — office equipment, appliances, consumer PCBs — not for an engine bay, a rooftop telecom enclosure, or a factory floor. If your BOM calls for -40°C operation, this part will not hold ±50 ppm stability at the cold end. ## Standby (Power Down) function The standby function disables the oscillator and puts the output into high-impedance. The disable current is 1 µA maximum. This is a hardware pin — the MCU or system controller pulls it low to shut down the clock tree and save power. No software configuration needed; it is a straight logic-level input. Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The footprint is a standard 4-pad land pattern — no via-in-pad required, no exposed thermal pad. It reflows on a standard lead-free profile and is supplied on Tape & Reel.","metaTitle":"DSC1033DC1-050.0000T MEMS XO 50 MHz CMOS 3.3V Microchip","metaDescription":"Active 50 MHz MEMS oscillator, 4 mA typ, 1 µA standby, 3.3V CMOS, ±50 ppm, 0°C to 70°C, 4-SMD.","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":"DSC1033, PureSilicon™","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"50 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"3.3V","Base Product Number":"DSC1033","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"0°C~70°C","Current - Supply (Max)":"4mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the standby power down function on DSC1033DC1-050.0000T?","answer":"The standby function disables the oscillator output and reduces the supply current to 1 µA maximum. It is controlled by a dedicated logic pin — pull it low to enter standby, high to enable the output. No software configuration is needed."},{"question":"Is DSC1033DC1-050.0000T suitable for automotive or industrial temperature ranges?","answer":"No. It is not qualified for automotive (AEC-Q100) or extended industrial (-40°C to +85°C) environments. For those applications, look at the DSC1001 or DSC1121 series from Microchip, which offer wider temperature grades."},{"question":"What is the closest pin-compatible alternative to DSC1033DC1-050.0000T?","answer":"Within the same DSC1033 family, the DSC1033DC1-050.0000 is the base part number — the 'T' suffix indicates Tape & Reel packaging.
