Output is HCSL — a differential, low-swing current-steering logic that is the standard reference for PCIe, 100GbE, and SAS/SATA controllers. The 100 MHz frequency is a common PCIe reference. Supply voltage spans 2.25 V to 3.6 V — a single rail that covers both 2.5 V and 3.3 V logic families. 6-SMD no-lead package, 2.50 mm x 2.00 mm body, seated height 0.90 mm max. The pads are on the bottom — no through-holes, so the oscillator sits entirely on the top layer. The DSC1104 series is a current catalog family; the DSC1104DE1-100.0000T is a standard configuration that Microchip continues to manufacture and distribute through authorized channels.","metaTitle":"DSC1104DE1-100.0000T Microchip MEMS XO 100 MHz HCSL Active","metaDescription":"DSC1104DE1-100.0000T from Microchip Technology — MEMS XO, 100 MHz, HCSL output, 2.25–3.6 V supply, ±50 ppm, -20°C to 70°C, 6-SMD no-lead.

When disabled, the maximum supply current drops to 95 µA, compared to 42 mA when running. This makes it suitable for battery-powered or duty-cycled designs where the oscillator is gated off between active periods."},{"question":"Can DSC1104DE1-100.0000T replace a quartz oscillator?","answer":"It can replace a quartz XO of the same frequency, output type, and package footprint, but the base resonator is MEMS, not quartz. The MEMS construction eliminates quartz aging and reduces sensitivity to mechanical shock and vibration. The ±50 ppm stability and -20°C to 70°C temperature range are comparable to a standard quartz XO; however, the HCSL output is differential — a direct drop-in requires the receiving device to have an HCSL-compatible input."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1104DE1-100.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1104DE1-100.0000T when reusing this data.
