XR21V14x UART

MaxLinear XR21V14x Universal Asynchronous Receiver Transmitter (UART) with USB 2.0 compliant bus interface is the industry's fastest UART series. The USB interface on the XR21V14x supports 12Mbps USB data transfer rate, USB suspend, resume, and remote wake-up operations. This UART operates from an internal 48MHz clock, requires no external crystal/oscillator, and can accurately generate any baud rate using the internal clock. The UART series includes an automatic transceiver direction control feature that simplifies the hardware for RS-485 applications. The XR21V14x UART is ideal for portable appliances, external converters (dongles), battery-operated devices, and more.
