Abstract
A low skew interface system for enabling an ASIC chip's receivers to latch information from one or more buses. The interface comprises a driver circuit connected to an internal clock of the chip for generating another clock signal with phase different from the phase of the internal clock. A delay element is located off the chip and connected to the driver circuit for delaying the clock signal, thereby generating a latch clock signal. The latch clock signal is sent back on-chip to enable the receivers to transfer information from one of the buses to the chip.
