Exar claims industry’s first multi-channel 66MHz PCI 3.0 compliant UART

Among analog building blocks, it is very often the “bread-and-butter” items that prove to be most useful. The Universal Asynchronous Receiver/Transmitter (UART) may lack some of the drama of a 24-bit analog-to-digital converter or a GHz op amp, but it provides a consistently reliable means of moving data from one place to another. Steve Ohr has a look at some 66-MHz PCI-compliant UARTs for telecomm servers.
