    摘要: An interface circuit providing a high speed bus. According to one embodiment, the interface circuitry includes a plurality of I/O pins coupled to a plurality of bus drivers, wherein each bus driver is configured to adjust the rise time, fall time, and drive strength of outputs signal on the I/O pins based on process-voltage-temperature ("PVT") conditions. The circuitry used to adjust the I/O outputs includes a slew rate control circuit, a current control circuit, and a delay lock loop ("DLL").
