QMC730 Series: Multi-function I/O

QMC730 Series: Multi-function I/O Description

QMC mezzanine modules plug into a carrier card to interface connected I/O and provide a variety of signal processing functions. Acromag QMC730 modules offer a high-density combination of analog input, analog output, digital I/O, and counter/timer functions. A PCIe bus interface provides communication to the carrier and host computer.

The analog input channels perform high-speed, high-resolution A/D conversion. Input ranges, calibration, and other operational parameters are individually selectable for each channel to provide great flexibility.

Analog output channels are also individually configured, allowing users to select ranges, trigger methods, and operation modes to accommodate application requirements. High-performance D/A converters provide fast and accurate output.

Digital I/O is configured as TTL-level input or output in groups of eight channels. Interrupts are software programmable for any bit change-of-state or level.

A multi-function, high-resolution counter/timer supports a variety of measurement operations. Programmable polarity, thresholds, and interrupts along with internal or external triggering offer extensive adaptability to meet your needs.

QMC modules adhere to the VITA 93 standard for small form factor (SFF) mezzanine modules. Two high-performance 80-pin connectors provide separate field I/O and PCIe bus host interfaces. Modules can deploy on a variety of carrier card platforms including PCIe expansion cards, 3U/6U Eurocards such as VPX and CompactPCI, VNX+ SFF cards, and many other architectures. The rugged design is well-suited for use in laboratory, industrial, defense, and aerospace applications.

QMC modules have a much smaller footprint than PMC/XMC modules. Single-width QMC modules are only 26 x 78.25mm which facilitates mixing and matching of multiple functions on a single carrier card for high-density I/O solutions. They are ideal for computing systems with strict size, weight, power, and cost (SWAP-C) limitations.

An Intelligent Platform Management Interface (IPMI) facilitates system management. The QMC EEPROM holds module information and sensor data that is accessible by a smart carrier card with an IPMC controller over an I2C interface.
