TCP469中文资料8 Channel Isolated RS232/RS422/RS485 Programmable Serial Interface数据手册TEWS规格书

描述 Description

The TCP468 is a standard 3U 32 bit CompactPCI module and offers 4 channels of high performance RS 422 serial interface.The module is based on the Exar XR17D154 universal PCI UART.The module offers front panel I/O with a DB-50 type connector. Each channel provides nearly full modem support by the following signals: RxD±, TxD±, RTS±, CTS±, DCD± and DTR±.On-board termination is provided for all input signals.Each channel has 64 byte transmit and receive FIFOs to significantly reduce the overhead required to provide data to and get data from the transmitters and receivers. The FIFO trigger levels are programmable and the baud rate is individually programmable up to 5.5296 Mbps. The UART offers readable FIFO levels.All channels generate interrupts on PCI interrupt INTA. For fast interrupt source detection the UART provides a special Global Interrupt Source Register.All serial channels use ESD protected transceivers. ESD protection is up to ±15KV.The TCP468 can operate with 3.3V and 5.0V PCI I/O signaling voltage.Software Support (TDRV002-SW-xx) for different operating systems is available.
