MaxLinear XR21B1411 Enhanced Full-Speed UART

MaxLinear XR21B1411 is an enhanced Universal Asynchronous Receiver and Transmitter (UART) with a USB interface. The USB interface is fully compliant to Full Speed USB 2.0 specification that supports 12Mbps USB data transfer rate. The USB interface also supports USB suspend, resume and remote wake-up operations. The XR21B1411 operates from an internal clock that is programmable to 6, 12, 24 or 48MHz. Therefore, no external crystal/oscillator is required as in previous generation UARTs. With the fractional baud rate generator, any baud rate up to 12Mbps can be accurately generated using the internal clock.
