If you are clocking a PCIe switch, a SerDes PHY, or a 100 MHz Ethernet MAC, this output type matches the input stage directly. The supply range spans 2.25V to 3.6V — a single part works on a 2.5V or 3.3V rail without a separate LDO. At 42 mA max supply current, the thermal load in the 3.2 mm × 2.5 mm package is modest; no special pad or airflow is needed. ## Standby function for power-sensitive designs For battery-powered equipment that sleeps between transmissions, this lets the oscillator share the same enable signal as the downstream PHY — no separate load switch required. ## Active lifecycle — available for new designs The part is in production and can be quoted to order for both prototype and volume BOM lines. The MEMS resonator means lead times are typically shorter than quartz equivalents; availability is confirmed at RFQ.","metaTitle":"DSC1104CI5-100.0000 MEMS XO, HCSL 100 MHz","metaDescription":"Active MEMS oscillator, HCSL output at 100 MHz, ±10 ppm stability, -40°C to +85°C, 6-SMD no-lead.

It is the standard output for PCIe reference clocks and other high-speed serial interfaces. The swing is 700–900 mV into a 50-Ω termination to ground."},{"question":"What supply voltage does the DSC1104CI5-100.0000 need?","answer":"It operates from 2.25V to 3.6V, so it works on either a 2.5V or 3.3V rail without an extra regulator."},{"question":"Is the DSC1104CI5-100.0000 RoHS compliant?","answer":"The evidence does not explicitly state RoHS compliance. The package is a standard 6-SMD no-lead, which is typically RoHS-compliant in Microchip's DSC1104 series, but confirm with the datasheet or your compliance team for your specific application."},{"question":"Can I replace a quartz oscillator with this MEMS oscillator?","answer":"Yes, if the quartz part is a 100 MHz XO with HCSL output in a 3.2 mm × 2.5 mm 6-pin footprint. The MEMS resonator is more shock- and vibration-tolerant than quartz, and the ±10 ppm stability is equivalent to many quartz XOs.
