The Mercury Computer Systems / Echotek RWEZ-2-L200 is a dual RACEway/RACE++ 2-slot backplane overlay engineered to establish dedicated high-speed communication paths between processing elements in VME-based multiprocessing systems. This overlay supports both RACEway 1.0 and RACE++ protocols, allowing flexible protocol selection based on system requirements.
Technical Specifications
• Supported Protocols: RACEway 1.0, RACE++
• Clock Speed Options: 40 MHz or 66.66 MHz
• Connector Configuration: 3-row or 5-row connector options available
• Backplane Interface: VME backplane mounting via mechanical attachment points
– Key Features
The RWEZ-2-L200 operates as a protocol-agnostic overlay, supporting both RACEway 1.0 and RACE++ without requiring design changes. Dual operating frequencies—40 MHz and 66.66 MHz—accommodate varying system bandwidth requirements. Two connector configurations (3-row and 5-row) provide layout flexibility for different VME backplane architectures. The 5-row variant offers a reduced-row option with D and Z rows removed for constrained installations.
– Typical Applications
This backplane overlay enhances performance in multiprocessing applications demanding low-latency inter-board communication. It serves systems requiring dedicated processing element interconnection with deterministic communication characteristics.
– Compatibility & Integration
Designed for integration with VME backplanes, the RWEZ-2-L200 mounts securely via backplane attachment points. Six part number variants address specific frequency and connector requirements:
• RWEZ-2S1 (12-0025/CC295B): 3-row, 40 MHz
• RWEZ-2SP (12-0025/CC296B): 3-row, 66.66 MHz
• RWEZ-2D1 (12-0025/CC297B): 5-row, 40 MHz
• RWEZ-2DP (12-0025/CC298B): 5-row, 66.66 MHz
• RWEZ-2SP-5 (12-0025/CC326B): 5-row reduced, 66.66 MHz
• RWEZ-2S1-5 (12-0025/CC327B): 5-row reduced, 40 MHz
The product inherits Echotek’s signal processing heritage following Mercury Computer Systems’ acquisition in July 2005.
