This application note considers general interfacing issues between the Cypress CY7B923/CY7B933 (HOTLink™) Transmitter/ Receiver and Cypress clocked FIFOs. The focus is on applications with a 36-bit data bus requiring high data transfer rates. A parallel FIFO solution is recommended for applications requiring large data bandwidth. Four FIFOs can achieve parallel data transfers on and off a 36-bit bus at rates of up to 280 Mbytes/s. The HOTLink serial link can transfer data at a serial rate of 330 Mbits/s. The FIFOs act as asynchronous storage buffers between the data bus and the serial link.
