I believe it is Stellamar -- they sell other IP and used to be in Chicago. Xilinx, Actel, and others offer their IP via a third party arrangement. There also are ADC in FPGA app-notes by Lattice, and Altera.
There was a company who was selling IP to do this sort of thing in FPGAs -- using an LVDS input pair to drive a soft core implemented in programmable digital fabric to implement an analog to digital converter. One of the advantages they talked about was using such a part in space -- if you already had a space-qualified digital FPGA -- it was quicker / cheaper / less risky to implement an ADC in the FPGA's digital fabric than to space-qualify an analog part.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
