The AN2025 interface module includes a paddle-board to interface to platform SVID signals. The paddle-board is designed to minimize the signal integrity impact to the motherboard SVID bus.
The paddle board motherboard connector consists of 8 pins and an additional ground strap. The ground strap is for motherboards that include only a 6 pin interface. (the strap can be left unconnected for 8 pin applications)
