UART - Can RX/TX macros be placed on separate CLK signals? (XAPP223)


Can the UART RX/TX macros be placed on separate CLK signals?


The UART_TX, UART_RX macros need not be placed on the same clock signal. The macros can be clocked with different clocks, as long as the BAUD rate connecting the two is the same.

For more information on matching BAUD rates, please see the Xilinx Application Note (Xilinx XAPP223): "200 MHz UART with Internal 16-Byte Buffer."
