PMC-Linecard




Connect a PMC to a host slot with a flexible cable interface.

PMC-Linecard provides a 33/32-33/66 extension between a PMC and Host. The design is optimised for production test. The PMC-Linecard host interface is installed into the host computer PMC slot. The PMC - PCI interface is turned to route to the right side. The cables extend the length and provide a hinge. The PMC-Linecard PMC interface is designed to mount to a PMC which is component side up. The host side and cables can remain attached to the host and the cables used as a hinge to allow PMC´s to be installed, tested and removed.

Two PC boards are provided to mount to the host and PMC. The boards are interconnected with flex cables and a separate power cable. The flex cables provide a flexible interface which allows the PMC to be relocated conveniently. The PC board on the PMC side has been minimized to allow maximum access to the hardware on the PMC for debugging purposes.

The PCI signals are terminated with series resistors on the A/D lines and Schottky diodes on the control signals. The flex cable signals are intersperced with ground. The clock is buffered with a "zero delay" PLL. +12, -12, 5V, 3.3V and Ground are interconnected with the power cable because the FLEX does not have sufficient current carrying capabilities. The host side board requires 5V and ground to operate the zero delay buffer. No other power is required by the PMC-Linecard. The User IO [Pn4] has some signals connected in a non general way. If you are using Pn4 please check the table below to see if this design is appropriate for your needs. The PMC-Extendio II is more appropriate in most cases.

To operate: simply plug and play. Install the board marked Plugs into Host into the carrier side and the board marked Plugs into PMC into your PMC. There are 5 cables. The 4 flex cables are mounted to the matching flex cable sockets. The board is designed to provide direct [non-twisted] interconnects when the boards are aligned. The fifth cable is for power. The cable is keyed for ease of use.


PMC-Linecard Features

  • Size
  • minimized PMC card on PMC side.

  • Clocks
  • Zero Delay buffered PCI clock signal. 33 or 66 MHz PCI reference supported. 33 Mhz. tested.

  • PMC / PCI Bus Width
  • 32 and 64 bit operation supported

  • Pn4
  • The user IO connector Pn4 is routed through the PMC-Linecard with some unique connections. Pins 2, 8, 9,18,19, 28, 29, 38, 39, 43, 44, 47, 49, 63 are tied to ground. 54-57 are tied to 3.3V. 58, 59, 60 are tied to +12V. 61 is tied to -12V. All signals which are tied to a voltage are not connected to the host Pn4 IO pins.

  • Cable interface
  • 4 Flex cables are utilized for PCI and User IO interconnection. Power is routed via a separate cable assembly. 2 4" flex cables and 2 6" flex cables are provided.

  • JTAG Interface
  • The PMC JTAG pins are supported with a JTAG connector mounted to the host side card.

  • Interrupts
  • The PMC interrupts are routed through to the host.

  • Power Requirement
  • +5V internally, +5V, +12V, -12V, +3.3V current determined by PMC attached. All voltages are provided with filter capacitors.

  • Signal Conditioning
  • Schottky diodes are used to clamp the PCI control signals and series terminations are used to condition the A/D bus.


    PMC-Linecard Benefits

  • Speed
  • The design of the PMC-Linecard is passive - no delays are added to the PMC access. Maximum speed of operation is retained with the PMC-Linecard.

  • Price
  • The PMC-Linecard can prove to be an indispensable tool at a nominal cost.

  • Ease of Use
  • Plug and play interface - plug in the hardware and operate. No software to install. Boards are marked with location of installation.

  • Availability
  • We keep the PMC-Linecard is in stock. Send in your order, and in most cases have your hardware the next day.

  • Size
  • The PMC-Linecard is a minimized PMC board. The mounting holes and connector locations are retained. The rest of the card is minimized to provide maximum exposure of components on the PMC and Host boards.

  • PMC Compatibility
  • The PMC-Linecard is a special purpose card and is not PCI compliant. The PMC-Linecard has features to minimize the effects of the longer cable interface to allow proper operation of the PMC isolated from the host card. The PMC-Linecard is the second in a series of cable interconnected PCI boards by Dynamic Engineering. [PMC-ExtendIO, PMC-Linecard, and PMC-ExtendIO II]. All of the designs are successful, providing maximum flexibility without sacrificing signal integrity.
