I/O Library with LVDS in SkyWater 90nm

Standard GPIO, I2C-compatible ODIO, analog I/O, and integrated LVDS for robust mixed-signal and moderate-speed differential interfaces

SkyWater 90nm S90 View all specifications

Overview

A SkyWater I/O Library combining standard GPIO, I2C-compatible ODIO, analog I/O, and integrated LVDS for robust mixed-signal and moderate-speed differential interfaces.

The Certus S90 Mixed-Signal I/O Library is a silicon-proven I/O platform for the SkyWater 90nm process, supporting single-ended digital I/O, ODIO, analog pads, and an integrated 3.3V LVDS macro. The library enables flexible pad-ring construction using inline or dual-staggered cells and is optimized for reliable operation across wide voltage and temperature ranges. Integrated LVDS supports point-to-point differential links up to 1.16 Gbps without the complexity or power overhead of a full SerDes solution.
