Method and apparatus for high frequency data transmission and testability in a low voltage, differential swing design

摘要

A high frequency data transmission circuit including design for testability (DFT) features. An integrated circuit includes core control logic to provide a data signal and output drive logic including a local data latch and a transmitter. The data latch receives the data signal and provides true and complementary forms of the data signal to the transmitter over symmetrical signal paths. The transmitter provides an output signal to an external receiver.
