VME-ADC

An ADSP-21060 SHARC based 6U VME card with two 65 MSPS ADCs at the front, the VME-ADC is an extremely powerful data acquisition platform,for large-bandwidth applications

VME-ADC: SONAR Systems, SONAR sub-systems

Overview

The VME-ADC board from Mistral Solutions is a high speed data acquisition system for large bandwidth applications. It is a 6U VME card,with two 65 MSPS ADCs at the front supported by an ADSP-21060 SHARC processor. It supports either an external or internal sampling clock and te external interfaces are terminated on the front panel through SMB connectors.

The VME-ADC board supports dynamic DC-offset control of analog channels, and FIFO for temporary storage of data.The onboard processor is supported by a local BOOT FLASH and, hence, can work in a standalone mode with no dependency on the VME bus. All the 6 link ports of the DSP are terminated on a high density 120-pin connector.

The Board Support Firmware provides the user with options to carry out self-test and configure other programmable options on the board. This VME based dual-channel high speed data acquisition system can be used along with Mistral’s V12S: a high-end signal processing platform
with 12 Analog Devices ADSP-21160 SHARC processors.
