Product details

125 MHz HCSL reference clock — MEMS base

The HCSL (High-Speed Current Steering Logic) output swings differentially and is the de facto standard for PCIe reference clocks — no external termination resistors to a bias voltage, just a pair of 50-Ω traces to the load.

Supply range and standby power-down

Housed in a 6-SMD, no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm. The part is supplied in tube. If tape-and-reel is needed for automated assembly, confirm the reel option with the distributor at quote time — the base product number DSC1104 supports multiple packing codes.

Microchip lists the DSC1104CI5-125.0000 as Active.

Frequently asked questions

What is the output type of the DSC1104CI5-125.0000?

HCSL (High-Speed Current Steering Logic) — a differential output that meets the PCIe reference clock standard. It swings approximately 700 mV peak-to-peak into a 50-Ω load and requires no DC bias termination.

Does the DSC1104CI5-125.0000 have a standby or power-down function?

Yes. The function pin is labeled Standby (Power Down). When asserted, the output enters high-impedance and the supply current drops to 95 µA max.

Is the DSC1104CI5-125.0000 compatible with a 2.5 V supply?

Yes. 2.5 V is within the 2.25 V to 3.6 V range. The HCSL output swing scales slightly with supply voltage but remains within the PCIe jitter budget at 2.5 V.

What is the frequency tolerance of the DSC1104CI5-125.0000?

This includes initial accuracy, temperature drift, and aging.
