Tews TCP460
cPCI	PowerPC	v. 4.0
Multiport Serial I/O

Tews' TCP460 is a standard 3U 32-bit CompactPCI module and offers 16 channels of high-performance serial interface.

Five different standard modules are available: The TCP460-10 provides 16 RS232 interfaces. The TCP460-11 provides 16 RS422 interfaces. The TCP460-12 provides 8 RS232 and 8 RS422 interfaces. The TCP460-13 provides 12 RS232 and 4 RS422 interfaces. The TCP460-14 provides 4 RS232 and 12 RS422 interfaces. Other configurations are available as factory option on a per-channel basis.

A transparent 32-bit / 66 MHz PCI-to-PCI Bridge provides access to the two Exar XR17D158 octal PCI-UARTs. The PCI-to-PCI Bridge allows 32-bit accesses on the local PCI bus and permits the high data throughput necessary for the high-performance serial interfaces.

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 921.6 kbps for RS232 channels and 5.5296 Mbps for RS422 channels. The UART offers readable FIFO levels.

Interrupts are supported. For fast interrupt source detection each octal UART provides a special global interrupt source register.

All serial channels use ESD protected transceivers up to ±15KV according to IEC 1000-4-2.

The TCP460 can operate with 3.3V and 5.0V PCI I/O signaling voltage.
