New PMC-E2001 Delta-sigma PMC features 16-bit resolution with 8 Analog Outputs and 4 Analog Inputs

HIGH WYCOMBE, UK October 3, 2012Curtiss-Wright Controls Defense Solutions (CWCDS), a business group of Curtiss-Wright Controls, has introduced its third generation waveform generating rugged PMC mezzanine card, the new PMC-E2001, designed for demanding audio and acoustic applications. The new low-cost, high resolution analog input and output card features 16-bit resolution, with performance rated at 92dB (typ) DAC SFDR and 90dB (typ) ADC SFDR. This enhanced re-design of the company’s popular PMC-E2001.

With support for eight (8) Analog Out and four (4) Analog In signals, this delta-sigma PMC module comprises eight pseudo differential outputs with 16-bit resolution and simultaneous update rates of >96ksps on each channel combined with four differential inputs with 16-bit resolution and up to 96 kHz sample rate. The updated card, which is provided in rugged conduction cooled packaging, maintains form, fit and function with the first generation PMC-E2001. However, the third generation is initially available in a rugged conduction-cooled format only. This third generation card is designed to mitigate obsolescence and support the very long program lifecycles typical to defense and aerospace market. The PMC-E2001 speeds and simplifies the integration of high performance acoustic/audio wave generation into demanding applications such as Sonar Simulation/Stimulation, Audio Output, Complex Waveform Generation, and Acoustics.

“Curtiss-Wright is one of the defense market’s leading experts in mitigating obsolescence and ensuring long lifecycle availability of rugged COTS technology such as our second generation PMC-E2001 acoustic waveform generator PMC module,” said Lynn Bamford, vice president and general manager of Curtiss-Wright Controls Defense Solutions. “From the first generation of this product to final shipments of this card we are now forecasting an impressive total lifespan of >15 years.”

The PMC-E2001 provides precise waveform generation and reconstruction in audio and acoustic applications. Its output module is designed with 256x over-sampling delta-sigma DAC technology with each output channel incorporating a 3rd order Bessel reconstruction filter to achieve 92dB (typ) Spurious Free Dynamic Range, SFDR. The card’s input module is designed with 256x over-sampling delta-sigma ADC technology. Its internal filtering ensures that SNRs of 86dB are readily achieved. Provision has been made for an external over-sampling clock via the front panel, and a user-selectable internal sample clock. The internal sampling clock utilizes a frequency synthesizer driven by a precision high stability master oscillator to provide high quality sample clock sources.

The PMC-E2001 features a PCI rev. 2.1 compliant interface with an integral DMA controller for transferring data directly between the host memory and the local PMC-E2001 buffer memory. PMC-E2001 offers a total of 6MB of local buffer storage, with 4MB allocated to the active DAC channels and 2MB allocated to the active ADC channels.
