PCI Universal Asynchronous Receiver-Transmitters (UARTs) are designed for use in system boards or add-in cards. MaxLinear offers pin compatible 2-, 4-, and 8-channel versions so a single design can support 4 or 8 ports.
The 4-channel and 8-channel PCIe UARTs have a proprietary master/slave expansion bus interface that enables up to 16 ports on a single x1 PCIe lane. These UARTs are software compatible with the industry-standard 16550 UARTs. Native support for MaxLinear’s PCIe UARTs is built-in to the latest Linux kernels. Custom software drivers for Windows, Windows Server, Windows Embedded Compact, Linux, VxWorks and QNX are also available.
