New PCI Express Boards Enable Robust Synchronous Serial Communications

Posted on

Sealevel Systems, Inc. today announced the release of two new single-port PCI Express serial I/O adapters designed for avionics, satellite, radar, and other applications that require robust synchronous communications. Both boards use the popular Zilog Z85230 Enhanced Serial Communications Controller (ESCC) for maximum compatibility with a variety of interfaces and protocols.

The 5102e multi-interface board is configurable for RS-232, RS-422, RS-485, RS-530, RS-530A or V.35, while the 5103e has an RS-232 interface. Both boards support data rates up to 128K bps. A digital phase lock loop (DPLL) circuit is included in each design for reliable communication when using NRZI or FM encoding.

Sealevel’s SeaMAC synchronous serial driver provides HDLC/SDLC protocols as well as certain configurations of monosync, bi-sync and raw modes for critical communication development and support. Software utilities are included to speed application development and to assist in field installation.

Standard operating temperature range is 0°C to 70°C, and extended temperature versions operating from -40°C to 85°C are available.

Like all Sealevel I/O products, the 5102e and 5103e are backed by free technical support and a lifetime warranty.
