Chip set with just one pilot pin for using a graphics interface reference voltage installs on a carrier printed circuit board to control an accelerated graphics interface.

摘要

Installed on a carrier printed circuit board (50) to control an accelerated graphics interface (44), a chip set (40) can have a core switching circuit (41), a multiplexer (48) and a comparator (47) or can connect to a multiplexer through a single pilot pin for graphics interface reference voltage. Coupling two connectors for the carrier printed circuit board and the accelerated graphics interface can regulate internal reference voltages
