GENERAL DESCRIPTION

The high speed ADC FIFO evaluation kit includes the latest
version of ADC Analyzer and a buffer memory board to capture
blocks of digital data from the Analog Devices, Inc., high speed
analog-to-digital converter (ADC) evaluation boards. The FIFO
board is connected to the PC through a USB port and is used with
ADC Analyzer to quickly evaluate the performance of high speed
ADCs. Users can view an FFT for a specific analog input and
encode rate to analyze SNR, SINAD, SFDR, and harmonic
information.
The evaluation kit is easy to set up. Additional equipment needed
includes an Analog Devices high speed ADC evaluation board,
a signal source, and a clock source. Once the kit is connected
and powered, the evaluation is enabled instantly on the PC.
The HSC-ADC-EVALB-DCZ can be used with single and multi-
channel ADCs and converters with demultiplexed digital outputs.

WARNING AND LEGAL TERMS AND CONDITIONS.

PRODUCT HIGHLIGHTS

1. Easy to Set Up. Connect the included power supply and
signal sources to the two evaluation boards. Then connect
to the PC and instantly evaluate the performance.
2. ADIsimADC™. ADC Analyzer supports virtual ADC
evaluation using Analog Devices proprietary behavioral
modeling technology. This allows rapid comparison between
multiple ADCs, with or without hardware evaluation boards.
For more information, see the AN-737 at www.analog.com.
3. USB Port Connection to PC. The PC interface is a USB 2.0
(1.1-compatible) connection. A USB cable is provided in the kit.
4. FIFO of 32 kB. The FIFO stores data from the ADC for processing.
A pin-compatible FIFO family is used for easy upgrading.
5. Up to 133 MSPS Encode Rate on Each Channel. Single-channel
ADCs with encode rates of up to 133 MSPS can be used with the
FIFO board. Multichannel and demultiplexed output ADCs can
also be used with the FIFO board with clock rates up to 266 MSPS.
6. Supports ADC with Serial Port Interface (SPI). Some ADCs
include a feature set that can be changed via the SPI. The FIFO
supports these features through the existing USB connection
to the computer without requiring additional cabling.
