and Hypersignal®-Macro development
software (see below)
Applications
The Sig5120-8 may be used in a variety of applications including radar, satellite, wireless IF digitizing, ultrasound, disk drive testing, CCD camera digitizing, process control, transient capture, aerodynamic testing, and other high signal rate applications. The Sig5120-8 also targets portable instrumentation where low power consumption is critical.
Conversion Technology
The Sig5120-8 uses the Texas Instruments ADS5120 low-power CMOS A/D converter to deliver high performance and precision. The ADS5120 device uses a switched capacitor, 10-stage pipeline architecture to sample inputs at up to 40 MHz.
Compatibility with DSP Boards and Other I/O Options
When used with SigC54xx, SigC55xx, and SigC67xx PC/104 and PCI boards, the Sig5120-8 module can be combined with a variety of analog, digital, and telecom I/O options
Multichannel 16-bit sigma-delta analog I/O Quad or single T1/E1 telephony interface (integrated framers and transceivers), available both at RJ-45 connectors on board backplate and MVIP H.100 connector 8-line POTS telephony interface Dual RS-232 asynchronous serial ports USB 2.0 interface Quad (4) RS-422/423 synchronous serial ports Boot/FLASH EEPROM 1149.1 JTAG header
Specifications and Data Sheets
Sig5120-8 Module Software Support
Sig5120-8 modules, when used with SigC54xx, SigC55xx, and SigC67xx PC/104 and PCI boards, are supported by Signalogic off-the-shelf DSP software products designed for DSP-based real-time processing and C54/55xx and C67xx DSP code development, including:
Hypersignal®-Macro and Hypersignal-Acoustic software
series, which offer a number of simulation and real-time instrument functions. Simulation
functions include DSP and math functions, time domain display (including waterfall,
contour, magnitude, unwrapped phase), difference equation, digital FIR and IIR filter
design, sampling rate conversion, frequency zoom, wavelet transform, minimum phase
calculation, and many more. Instrument functions include spectrum analyzer, digital
oscilloscope, stimulus & response measurement, continuous signal generation,
real-time; "snap-in"; filtering, continuous disk record and generate, and more.
DirectDSP®
is a Windows library that provides low-level and high-level calls for user-defined C/C++,
Visual Basic, MATLAB®, or LabVIEW® programs. The DirectDSP API
includes low-level hardware control functions such as reset/run/hold, register access,
block memory transfer, DSP executable file download, etc. High-level functions include
waveform file acquire/generate, continuous signal generation and execution of any
arbitrary Hypersignal DSP or math function. DirectDSP includes strip-chart recorder,
digital oscilloscope and digital tape recorder demo program and source code examples. The C67xx Source Code Interface contains numerous C67xx
algorithms and functions in source and binary form, such as optimized FFTs, filters,
matrix, transcendental, trig, signal manipulation function, processor and card
initialization and analog I/O examples, etc. These functions form the basis of
higher-level software functions and instruments; modification can be used to customize
Hypersignal or DirectDSP software operation. User-defined C routine hooks are provided for
real-time algorithm development. The C54/55xx and C67xx SCIs can be used as a basic foundation for user-defined real-time DSP systems and products.
