What is a PMC module?

What is a PMC module?

Serial communication modules are serial cards that provide one or more serial ports to a host computer. The card interfaces the host with a PMC bus and adds RS232 / RS422 or other types of serial ports. The basic PMC module is a 32-bit data bus that uses two 64-pin connectors from the PCI bus.

What is PMC and XMC?

XMC, or Switched Mezzanine Card, (PMC with high-speed serial fabric interconnect) defined by the VITA 42 standard. XMC specifies a fifth connector (“P15”) that supports PCI Express (VITA 42.3) or other high speed serial formats such as Serial RapidIO (VITA 42.2) and Parallel RapidIO (VITA 42.1).

What is mezzanine form factor?

Mezzanine is a term used to describe the stacking of computer component card s into a single card that then plugs into the computer bus or data path.

What is a switched mezzanine card?

XMC (or Switched Mezzanine Card) owes its existence to the embedded computing community’s acceptance of a groundbreaking proposal in 2002 to standardize gigabit serial switched fabrics and defined in the ANSI/VITA 42.0 specification.

What is PCI in computer architecture?

Peripheral Component Interconnect (PCI) is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard.

What is a carrier card?

Carrier cards and carrier boards, also referred to as “baseboards”, implement application specific functionality, I/O interfaces, peripherals and power supplies for computing applications.

What does Xmc stand for?

cross-market microcontrollers
The XMC microcontrollers use the 32-bit RISC ARM processor cores from ARM Holdings, such as Cortex-M4F and Cortex-M0. XMC stands for “cross-market microcontrollers”, meaning that this family can cover due to compatibility and configuration options, a wide range in industrial applications.

What is the use of mezzanine card?

A PCI mezzanine card (PMC) is a printed circuit board that is used to extend the connectivity or function of a compatible computer system, typically for the VMEbus, Futurebus+ and other computer systems supporting the PCI specification.

What is OCP card?

ConnectX OCP 3.0 adapter cards are part of Mellanox’s 10, 25, 40, 50, 100 and 200 GbE end-to-end portfolio for data centers which also includes switches, application acceleration packages, and cabling to deliver a unique price-performance value proposition for network and storage solutions.

What does a mezzanine card do?

What kind of PCI card can I use with PMC?

Carrier cards that accept PMCs are usually made in the Eurocard format, which includes single, double and triple-height VMEbus cards, CompactPCI (cPCI) cards and more recently, VPX cards. One PMC fits on a standard 3U carrier card while 6U models (typical for VMEbus cards) can carry up to two PMCs.

What is the standard size of a PMC card?

The standard also defines a double-sized card, but this is rarely used. Carrier cards that accept PMCs are usually made in the Eurocard format, which includes single, double and triple-height VMEbus cards, CompactPCI (cPCI) cards and more recently, VPX cards.

How many bus connectors does a PMC need?

A PMC can have up to four 64-pin bus connectors. The first two (“P1” and “P2”) are used for 32 bit PCI signals, a third (“P3”) is needed for 64 bit PCI signals. An additional bus connector (“P4”) can be used for non-specified I/O signals.

Which is ANSI / VITA standard for conduction cooled backplanes?

This standard is an extension of the VME64x Standard, ANSI/VITA 1.1-1997. It defines a keying system that can be added to VME64x boards and backplanes in a conduction cooled environment (IEEE 1101.2) where keying as defined in the VME64 Extensions standard cannot be applied.
