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)

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
