Supply voltage spans 2.25V to 3.6V, covering the 2.5V and 3.3V rails common in FPGA and switch ASIC clock trees. The wide input range also absorbs a poorly regulated 3.3V rail that dips under load without losing lock. ## Industrial temperature band and MEMS reliability Maximum supply current is 42 mA at 316 MHz — the HCSL output stage draws more than a CMOS oscillator at the same frequency, but the differential signal integrity saves power at the receiver by eliminating the common-mode termination resistors a single-ended clock would need. ## Standby power-down function This is useful for systems that gate the clock to an idle PCIe lane or put the FPGA core into a low-power state while retaining the oscillator's startup time budget. ## 6-VDFN package and board layout Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits under a mezzanine card or on a tight FPGA-side clock fan-out.","metaTitle":"DSC1104CI2-316.0000 XO Oscillator 316 MHz HCSL MEMS -","metaDescription":"Active Microchip DSC1104CI2-316.0000 XO (Standard) oscillator, 316 MHz HCSL output, MEMS resonator, -40°C to +85°C, 2.25V-3.6V supply.","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":"DSC1104","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"316 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","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":"DSC1104","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"42mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"-"}},"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 and supply voltage range of the DSC1104CI2-316.0000?","answer":"The output is HCSL (High-Speed Current Steering Logic), the differential standard used for PCIe reference clocks.
