Each channel can operate up to 10 Mbits/s. Optional 32 Kbyte FIFO buffer for both transmit and receive data on each channel (256 Kbytes total) provides for a smooth and efficient interface between the serial interfaces and the PMC host computer. The board is based on the Zilog Z16C30 high speed Integrated Universal Serial Controller (USC) which supports Asynchronous, Isochronous, Bisync, Monosync, HDLC, SDLC, External Sync and Nine-Bit protocols. The USC chip provides full duplex operation with baud rate generators, digital phase-locked loop for clock recovery and a full duplex DMA interface. The board only requires simple read/write statements to operate.
