Fri, 06/07/2013 - 11:01am

Sealevel’s (Liberty, SC) 7203e PCI Express serial interface provides two optically isolated serial ports, each individually configurable for RS-232, RS-422, or RS-485. Each serial port utilizes a high-performance UART with 128-byte Tx/Rx FIFOs that enables data rates to 460.8K bps for reliable high-speed communications in data intensive applications. The 7203e is the perfect choice for electrical noisy conditions and protects against harmful current loops and power surges commonly found in industrial environments, says the company. The board’s 16C952 UART UART includes 9-bit framing support and is register compatible with legacy 16550 software applications. In addition, the board derives a 62.5 MHz clock from the PCI Express link.
