PMC66-16AO16-16-F0-SE General Standards 16-Bit High-Speed Analog Output Board

The General Standards 66-16AO16 Series 16-Bit High-Speed Analog Output Boards contain sixteen 16-bit D/A converters (DAC's), and all supporting functions necessary for adding precision high-speed differential or single-ended analog output capability to a PMC, PCI, cPCI or PC104-Plus application. Output ranges are software-selectable as ±10 Volts, ±5 Volts or ±2.5 Volts. The board is functionally compatible with the IEEE PCI local bus specification Revision 2.3, and supports both 66MHz and 33MHz PCI bus speeds with universal signaling. Unique FIFO buffer controls support the seamless sequencing of successive waveforms through a single buffer port. In less demanding applications, the outputs can be updated individually. Hardware clock I/O permits synchronization with a variety of GSC products, including Sigma-Delta ADC boards.

A PCI interface adapter provides the interface between the controlling PCI bus and the internal local controller. Sixteen output channels are controlled through an analog output FIFO buffer, and can be updated either simultaneously or sequentially. The output sample rate can be controlled by an internal rate generator or by an external clock. The local controller manages all input/output configuration and data manipulation functions, including autocalibration. Analog output levels are initialized to zero (midrange). Multiboard synchronization is supported.

This product is designed for minimum off-line maintenance. On-demand autocalibration eliminates the need for disconnecting or removing the module from the system for calibration. All analog input and output system connections are made through a single 68-pin I/O connector. Power requirements consist of +5 VDC, in compliance with the PCI specification, and operation over the specified temperature range is achieved with conventional convection cooling.
