This user's guide provides a reference document for the SRC4382EVM-PDK and SRC4392EVM-PDK product development kits. The kits include either an SRC4382EVM or an SRC4392EVM daughterboard, as well as a DAIMB motherboard. Together, the daughter and mother boards form a modular platform for evaluating the function and performance of the Texas Instruments' SRC4382 and SRC4392 integrated circuits. Applications software is provided with the PDK for writing and reading registers and data buffers integral to the SRC4382 and SRC4392 devices. The software communicates with the device under test using the USB slave interface on the DAIMB board. The software requires a host PC running the Microsoft Windows™ 2000 or XP operating system.
