Pentek Extends I/O Modularity and Versatility with PMC Expansion Module

6/29/2004 - Pentek, Inc., the industry pioneer of VME board-level technology, announced a PCI mezzanine card (PMC) expansion board designed as a companion for Pentek DSP processor baseboards for VME. The Model 9220 incorporates three 64-bit/66 MHz PMC module sites, each accepting industry-standard modules for a wide variety of interface and communication functions.

The Model 9220 extends the processor baseboard’s PMC connector into a second VMEbus slot where the three PMC modules can be mounted. In addition, two VIM (Velocity Interface Mezzanine) modules can be mounted on the baseboard. The capability of combining up to two VIM and three PMC modules, simultaneously, on a single baseboard gives the Model 9220 the I/O modularity and expandability unlike any other product in the industry. The 9220 offers unprecedented modularity for both new and existing VME COTS systems for software radio, signal processing and data acquisition applications.

“The Model 9220 significantly broadens the range of I/O options for COTS system designers,” says Rodger Hosking, vice president of Pentek, Inc. “Not only can our customers take full advantage of high-performance VIM modules, but now they can add up to three PMC modules for a wide array of miscellaneous I/O functions for system-specific interfaces. By choosing from thousands of off-the-shelf components, engineers can now create custom, two-slot sub-systems delivering tremendous performance, numerous high-speed internal interconnects, and just the right I/O characteristics.”

Superior System Performance and Connectivity
The Model 9220 architecture targets maximum connectivity, superior power management, and support for a wide range of PMC modules.

All three PMC sites accommodate both 3.3V and 5V PMC modules, and power is drawn directly from the VMEbus backplane, thus reducing power demands on the attached processor board.

The Model 9220 architecture features two 64-bit PCI buses, each capable of 33 MHz or 66 MHz speeds. This multiple bus design offers the user a great deal of flexibility in both I/O configuration and bus speed.

PCI Bus 1 offers a direct interface between the first PMC site and PCI Bus 0. This direct connection allows a 66 MHz PMC module mounted in PMC Site 1 to be mixed with slower modules while maintaining 66 MHz operation.

Connectivity between the P4 connectors of PMC Sites 1 and 2 is optionally available. This allows communication between the PMC modules using P4 I/O, such as Pentek’s 7131 A/D and Digital Receiver.

Development Tools for a Variety of Platforms
Pentek's VxWorks and TimeSys Linux board support packages provide software developers with a complete library of hardware initialization, control and application functions for Pentek baseboards with the 9220 installed. Pentek's ReadyFlow board support libraries offer an alternative to VxWorks and Linux, providing license-free eCos development tools and pretested examples.
