The HCSL swing (typically 700-800 mV peak-to-peak) reduces EMI compared to a single-ended LVCMOS clock at the same frequency, and the differential pair rejects common-mode noise on the PCB trace. If your PCIe reference clock or SerDes PLL expects HCSL levels, this oscillator mates without a level translator. No external load capacitors, no startup margin calculation. ## Supply flexibility and power gating At 42 mA max supply current, the oscillator draws about 140 mW at 3.3 V — budget that into the rail's total load. The 6-SMD No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits dense layouts. The no-lead construction means the terminations are flush with the package body; the PCB land pattern should match the manufacturer's recommended footprint for the 6-pad layout. Surface-mount reflow per JEDEC J-STD-020 is standard.","metaTitle":"DSC1124CE1-050.0000T 50 MHz HCSL MEMS Oscillator","metaDescription":"Active Microchip DSC1124 XO, 50 MHz HCSL output, MEMS resonator, ±50ppm stability, 2.25V-3.6V supply, Enable/Disable.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"HCSL","Series":"DSC1124","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"50 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 ~ 3.6V","Base Product Number":"DSC1124","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"42mA","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/11b93dcf3fe2344432ea2f214a7ea724.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output type of DSC1124CE1-050.0000T?","answer":"HCSL (High-Speed Current Steering Logic) — a differential output standard commonly used for PCIe reference clocks and other high-speed serial interfaces.
