The Enable/Disable function lets the system gate the clock output, pulling the supply current from 58 mA (max) down to 22 mA (max) when disabled. ## Industrial temperature grade and MEMS reliability The MEMS base resonator is inherently more shock- and vibration-tolerant than a quartz crystal — a practical advantage in motor-drive or automotive auxiliary applications. ## 6-SMD package and board layout Housed in a 7.00 mm x 5.00 mm 6-SMD package with an exposed pad (No Lead), the part requires a thermal-land pattern on the PCB for proper heat dissipation and mechanical stability. The seated height of 0.90 mm keeps it low-profile for mezzanine or card-edge applications.","metaTitle":"DSC1122AI1-133.3300T Microchip MEMS XO, LVPECL, 133.33 MHz","metaDescription":"Microchip DSC1122AI1-133.3300T MEMS XO, LVPECL output, 133.33 MHz, ±50 ppm stability, -40°C to 85°C, 2.25V-3.6V supply, 6-SMD, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVPECL","Series":"DSC1122","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"133.33 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1122","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"58mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9eb455e34e1b4ad4aed847bfc84d48fa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output logic of the DSC1122AI1-133.3300T?","answer":"The output is LVPECL (Low-Voltage Positive Emitter-Coupled Logic), a differential standard that requires 50-ohm termination to VCC – 2V.
