Product Overview

DP-VME-5114 is a 6U VME specification PMC carrier board that accommodates 2 PMC (PCI mezzanine daughter cards) in a single standard VME slot.

PMC sub cards can provide modular and cost-effective hardware solutions for process control, medical electronics, aerospace, defense, and telecommunications industries.

Working principle (PCI-PCI bridge)

On board PCI-PCI bridge chip (PCI6466): obtains the main PCI bus signal from the VME backplane P0 connector, bridges and generates the secondary PCI bus on the board; Two PMC slots are mounted on the secondary PCI bus.

Backplane P0 provides IDSEL, clock, PCI request/authorization signals; The backplane handles the rotation of interrupt lines, and the interrupt signal is transmitted back to the main PCI bus (P0) through the bridge chip.

I/O dual output:

Rear I/O: relying on VME64 high-density P2 connector to achieve high-density rear signal output;

Front I/O: The 25 pin D-Sub connector leads out 18 front I/O signals.

Detailed characteristics of PCI-PCI bridge (PCI6466)

Supports up to 33MHz/66MHz PCI bus, with internal arbitration, and supports up to 4 PCI devices on the secondary side.

Support burst transmission mode to improve throughput; The main and secondary bus traffic paths are independent of each other; Working in transparent mode.

The PMC module clock is provided by an external 33/66MHz crystal oscillator as a secondary PCI clock source.

The board generates 4 secondary interrupt requests, which are routed and forwarded to the main PCI bus.

Software Description

The PCI-PCI bridge on the board is automatically identified and enumerated by the operating system; The carrier board itself does not provide independent drivers.

The actual inserted PMC daughter card requires the corresponding operating system driver provided by the PMC daughter card itself to achieve full functionality.

Technical specifications

PMC compliance: Complies with IEEE P1386.1/Draft2.3 PMC specifications.

Electrical and mechanical interface: supports 2 standard single size PMC modules; Supports 64 bit, 66MHz PCI bus.

PCI standard: Following PICMG 2.0 R3.0 specification.
