摘要： An integrated circuit includes a local clock network that is operable to provide a first clock signal and an interface circuit that is coupled to receive the first clock signal from the local clock network. The interface circuit is operable to generate a second clock signal based on the first clock signal. A clock line is coupled to the interface circuit. The clock line has a fixed length. The second clock signal is provided to a multiplexer circuit through the clock line. The multiplexer circuit provides a third clock signal based on the second clock signal. Another clock network is coupled to receive the third clock signal from the multiplexer circuit.

摘要： A high speed serial interface comprises a rectilinear array of rows and columns of contact sites on a substrate. In the first four columns, pairs of transmitter and receiver contacts alternate row-by-row with pairs of ground contacts In the fifth column, there is a permanent (or hard) ground contact adjacent to each transmitter or receiver contact pair located in a row in the third and fourth columns and the remaining contacts in the fifth column are general purpose input/output (GPIO) contacts. As a result, up to 50 percent of the contacts in the fifth column may be GPIO contacts. In the sixth column, all the contacts are GPIO contacts.
