The MAX3785 6.25Gbps 1.8V PC Board Equalizer is a product of Maxim Integrated, which operates from a single 1.8V supply and compensates for transmission medium losses encountered with FR-4 transmission lines. This product is optimized for low-voltage, high-density, DC-coupled interconnections between the line card and switch card, allowing a system upgrade path while maintaining a legacy rate of 2.5Gbps to 3.125Gbps. The product is roughly the size of two 0603 passive components, which makes it easy to place and route.
The MAX3785 is a 6.25 Gbps, 1.8 V PC board equalizer designed for FR‑4 transmission lines. It combines an equalizer, limiting amplifier, and output driver, and works with both 8b/10b and scrambled data streams. The device operates from a single 1.8 V supply and supports legacy rates from 1.0 Gbps up to 6.4 Gbps.
The datasheet provides absolute maximum ratings, electrical characteristics, typical operating curves, and package information. It is offered in UCSP, WLP, and TDFN‑EP packages, with detailed pin descriptions and ordering tables. Revision history and contact information are also included.
