PMC interface reflects memory card [Copy link]

The reflective memory card with PMC interface is a hardware device used in real-time network. It integrates reflective memory on the card and connects to the computer through the PMC (PCI Mezzanine Card) slot of the computer.

Taking the common PMC-5565PIORC reflective memory card as an example, it has the following features:

High-speed, low-latency deterministic interface : Using a high-speed, easy-to-use fiber optic network (2.12Gbit/s serial), the transmission rate can reach 43MB/s (4-byte data packets) to 170MB/s (64-byte data packets), and the latency between nodes is in the hundreds of nanoseconds.

• Multi-node data sharing : up to 256 data sharing nodes.
• Long-distance transmission : up to 300 meters when using multi-mode optical fiber connection, and up to 10 kilometers when using single-mode optical fiber connection.
• Dynamic Packet Size : Packet size can be automatically adjusted between 4 and 64 bytes.
• Onboard Memory : With 128MB or 256MB onboard SDRAM with parity, local SDRAM provides fast read access time to stored data. Write operations are stored in local SDRAM and broadcast to other reflective memory nodes via high-speed fiber optic data paths.
• Efficient and stable : Network transmission does not require processor participation and does not occupy CPU resources; it supports error detection function, and the redundant transmission mode can suppress additional errors.
• Strong compatibility : applicable to a variety of host architectures.

When using the PMC interface to reflect the memory card, please note the following points:

• Must be used in conjunction with the PMC/PMI bracket as a replacement for the PCI-5565PIORC.
• Data written to the memory of one node is written to the memory of all nodes on the network to achieve fast synchronization and sharing of data.
• In actual applications, you may need to set the relevant switches on the reflective memory card to configure parameters such as redundancy mode, node ID, etc., and ensure the correctness of the fiber connection (such as connecting the outlet line to the inlet line, and the inlet line to the outlet line).

PMC interface reflective memory card is suitable for systems with high requirements for data real-time and communication performance, such as industrial control, aerospace, military and other fields, and can realize high-speed, real-time data sharing and communication between multiple devices or systems.

The specific ordering information is as follows:

• PMC-5565PIORC-110000: 128M multimode fiber;
• PMC-5565PIORC-111000: 128M single mode fiber;
• PMC-5565PIORC-210000: 256M multimode fiber;
• PMC-5565PIORC-211000: 256M single mode fiber.
