Baja68K Heurikon VME Real-Time Communications I/O Module

The Emerson / Heurikon Baja68K VME Module targets compute- and I/O-intensive applications like telecom switching, Intelligent Network switching, network control, LAN to WAN bridging and video-on-demand. The Baja68K features a 64-bit VME64 interface, on-card Ethernet, two serial ports and up to 64 Mbytes of DRAM. It also features a pair of 32-bit PMC expansion interfaces, which make it easy for designers to add custom and off-the-shelf third-party PMC cards. To address the vast investment in 680x0 applications code by communication system developers, Baja68K features a choice of a 66 MHz 68040 processor or a 68060 processor which is available at either 50 or 60 MHz. This choice of processors provides a convenient upgrade path from the moderately priced 68040 to the 68060 which features nearly three times the performance of the 68040.

The Baja68K's PMC (PCI Mezzanine Card) interface features two 32-bit expansion connectors. The two interfaces can accept either two single-wide or one double-wide module. I/O can be routed either to the front panel or out the P2 connector. Because it supports two PMC modules, the Baja is ide- ally suited to communications applications requiring support for multiple protocols. By mixing PMC modules the Baja can serve as a high-performance bridge between networks. The I/O flexibility and processor performance make the board ideal as a communication switch controller, and the two PMC slots ensure compatibility with most standard or custom switch interfaces.
