High Speed Converter Evaluation Platform

FEATURES

Xilinx Virtex-4 FPGA-based buffer memory board Used for capturing digital data from high speed ADC evaluation boards to simplify evaluation

64 kB FIFO depth

Parallel input at 644 MSPS SDR and 800 MSPS DDR Supports 1.8 V, 2.5 V, and 3.3 V CMOS and LVDS interfaces Supports multiple ADC channels up to 18 bits Measures performance with VisualAnalog

Real-time FFT and time domain analysis Analyzes SNR, SINAD, SFDR, and harmonics

Simple USB port interface (2.0)

Supports ADCs with serial port interfaces (SPI)

FPGA reconfigurable via JTAG, on-board EPROM, or USB On-board regulator circuit speeds setup

5 V, 3 A switching power supply included Compatible with Windows 98 (2nd edition), Windows 2000,

Windows ME, and Windows XP

EQUIPMENT NEEDED

Analog signal source and antialiasing filter Low jitter clock source

High speed ADC evaluation board and ADC data sheet PC running Windows 98 (2nd edition), Windows 2000,

Windows ME, or Windows XP Latest version of VisualAnalog

USB 2.0 port recommended (USB 1.1 compatible)

HSC-ADC-EVALC

PRODUCT HIGHLIGHTS

1.Easy to Set Up. Connect the included power supply along with the CLK and AIN signal sources to the two evaluation boards. Then connect to the PC via the USB port and evaluate the performance instantly.

2.USB Port Connection to PC. PC interface is via a USB 2.0 connection (1.1 compatible) to the PC. A USB cable is provided in the kit.

3.64 kB FIFO. The on-board FPGA contains an integrated FIFO to store data captured from the ADC for subsequent processing.

4.Up to 644 MSPS SDR/800 MSPS DDR Encode Rates on Each Channel. Multichannel ADCs with encode rates up to 644 MSPS SDR and 800 MSPS DDR can be used with the ADC capture board.

5.Supports ADCs with Serial Port Interface or SPI. Some ADCs include a feature set that can be changed via the SPI. The ADC capture board supports these SPI-driven features through the existing USB connection to the computer without additional cabling needed.

6.VisualAnalog™. VisualAnalog supports the HSC-ADC- EVALC hardware platform as well as enabling virtual ADC evaluation using ADIsimADC™, Analog Devices proprietary behavioral modeling technology. This allows rapid compari- son between multiple ADCs, with or without hardware evaluation boards. For more information, see AN-737 at www.analog.com/VisualAnalog.
