The MEMS resonator eliminates the quartz start-up reliability concerns common in high-vibration environments — a practical advantage for automotive and industrial applications where a crystal might fail under sustained shock. AEC-Q100 qualification means this oscillator has passed the full automotive-grade stress suite: temperature cycling, ESD, latch-up, and extended life tests. The Enable/Disable function lets you gate the output, dropping supply current from 32 mA max to 22 mA max when the clock is not needed. This is useful for power-sensitive designs where the oscillator can be shut down during sleep modes without a separate load switch. ## Supply voltage tolerance and package The supply range spans 2.25V to 3.63V, covering 2.5V and 3.3V rails without an external regulator. This wide tolerance simplifies the power tree — the oscillator can share a rail with other 3.3V logic or a 2.5V FPGA bank, reducing BOM count. Housed in a 6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The part ships in Tape & Reel (TR) packaging, standard for automated pick-and-place assembly.","metaTitle":"DSC1123CE1-156.2500T – Microchip MEMS XO, 156.25 MHz, LVDS","metaDescription":"DSC1123CE1-156.2500T: Microchip DSC1123 series MEMS XO, 156.25 MHz LVDS output, ±50 ppm stability, AEC-Q100 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVDS","Series":"DSC1123","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"156.25 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-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":"2.25V ~ 3.63V","Base Product Number":"DSC1123","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"32mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/32c33983bfd645bac8d0b2ac5207c872.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1123CE1-156.2500T AEC-Q100 qualified?","answer":"Yes, the DSC1123CE1-156.2500T carries AEC-Q100 ratings, meaning it has passed automotive-grade qualification for temperature cycling, ESD, and reliability stress.
