PRODUCT 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 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.
Two versions of the FIFO are available. The HSC-ADC-EVALBDC is used with multichannel ADCs and converters with demultiplexed digital outputs. The HSC-ADC-EVALB-SC evaluation
board is used with single-channel ADCs. See Table 1 to choose
the FIFO appropriate for your high speed ADC evaluation
board.

2. ADIsimADC™. ADC Analyzer supports virtual ADC
evaluation using ADI proprietary behavioral modeling
technology. This allows rapid comparison between multiple
ADCs, with or without hardware evaluation boards. For more
information, see AN-737 at www.analog.com/ADIsimADC.
3. USB Port Connection to PC. PC interface is a USB 2.0
connection (1.1-compatible) to the PC. A USB cable is
provided in the kit.
4. 32 kB FIFO. 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. Singlechannel ADCs with encode rates 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 or SPI. Some ADCs
include a feature set that can be changed via the SPI. The FIFO
supports these SPI-driven features through the existing USB
connection to the computer without additional cabling needed.

THEORY OF OPERATION
The FIFO evaluation board can be divided into several circuits,
each of which plays an important part in acquiring digital data
from the ADC and allows the PC to upload and process that
data. The evaluation kit is based around the IDT72V283 FIFO
chip from Integrated Device Technology, Inc (IDT). The system
can acquire digital data at speeds up to 133 MSPS and data
record lengths up to 32 kB using the HSC-ADC-EVALB-SC
FIFO evaluation kit. The HSC-ADC-EVALB-DC, which has
two FIFO chips, is available to evaluate multichannel ADCs or
demultiplexed data from ADCs sampling faster than 133 MSPS.
A USB 2.0 microcontroller communicating with ADC Analyzer
allows for easy interfacing to newer computers using the USB 2.0
(USB 1.1-compatible) interface.
The process of filling the FIFO chip or chips and reading the
data back requires several steps. First, ADC Analyzer initiates
the FIFO chip fill process. The FIFO chips are reset, using a
master reset signal (MRS). The USB microcontroller is then
suspended, which turns off the USB oscillator and ensures that
it does not add noise to the ADC input. After the FIFO chips
completely fill, the full flags from the FIFO chips send a signal
to the USB microcontroller to wake up the microcontroller
from suspend. ADC Analyzer waits for approximately 30 ms
and then begins the readback process.
During the readback process, the acquisition of data from
FIFO 1 (U201) or FIFO 2 (U101) is controlled via Signal OEA
and Signal OEB. Because the data outputs of both FIFO chips
drive the same 16-bit data bus, the USB microcontroller
controls the OEA and OEB signals to read data from the correct
FIFO chip. From an application standpoint, ADC Analyzer
sends commands to the USB microcontroller to initiate a read
from the correct FIFO chip, or from both FIFO chips in dual or
demultiplexed mode.
CLOCKING DESCRIPTION
Each channel of the buffer memory requires a clock signal to
capture data. These clock signals are normally provided by the
ADC evaluation board and are passed along with the data
through Connector J104 (Pin 37 for both Channel A and
Channel B). If only a single clock is passed for both channels,
they can be connected together by Jumper J303.
Jumpers J304 and J305 at the output of the LVDS receiver allow
the output clock to be inverted by the LVDS receiver. By default,
the clock outputs are inverted by the LVDS receiver.
The single-ended clock signal from each data channel is
buffered and converted to a differential CMOS signal by two
gates of a low voltage differential signal (LVDS) receiver, U301.
This allows the clock source for each channel to be CMOS,
TTL, or ECL.
The clock signals are ac-coupled by 0.1 μF capacitors.
Potentiometer R312 and Potentiometer R315 allow for fine
tuning the threshold of the LVDS gates. In applications where
fine-tuning the threshold is critical, these potentiometers can be
replaced with a higher resistance value to increase the
adjustment range. Resistors R301, R302, R303, R304, R311,
R313, R314, and R316 set the static input to each of the
differential gates to a dc voltage of approximately 1.5 V.
At assembly, Solder Jumper J310 to Solder Jumper J313 are set
to bypass the potentiometer. For fine adjustment using the pot,
the solder jumpers must be removed, and R312 and R315 must
be populated.
U302, an XOR gate array, is included in the design to let users
add gate delays to the FIFO memory chip clock paths. They are
not required under normal conditions and are bypassed at
assembly by Jumper J314 and Jumper J315. Jumper J306 and
Jumper J307 allow the clock signals to be inverted through an
XOR gate. In the default setting, the clocks are not inverted by
the XOR gate.
The clock paths described above determine the WRT_CLK1 and
WRT_CLK2 signals at each FIFO memory chip (U101 and
U201). The timing options above should let you choose a clock
signal that meets the setup and hold time requirements to
capture valid data.
A clock generator can be applied directly to S1 and/or S3. This
clock generator should be the same unit that provides the clock
for the ADC. These clock paths are ac-coupled, so that a sine
wave generator can be used. DC bias can be adjusted by
R301/R302 and R303/R304.
The DS90LV048A differential line receiver is used to square the
clock signal levels applied externally to the FIFO evaluation
board. The output of this clock receiver can either directly drive
the write clock of the IDT72V283 FIFO(s), or first pass through
the XOR gate timing circuitry described above.
SPI DESCRIPTION
The Cypress IC (U502) supports the HSC SPI standard to allow
programming of ADCs that have SPI-accessible register maps.
U102 is a buffer that drives the 4-wire SPI (SCLK, SDI, SDO,
CSB 1 ) through the 120-pin connector (J104) on the third or top
row. J502 is an auxiliary SPI connector to monitor the SPI
signals connected directly to the Cypress IC. For more
information on this and other functions, consult the user
manual titled Interfacing to High Speed ADCs via SPI at
www.analog.com/hsc-FIFO.

Note that CSB1 is the default CSB line used.

HSC-ADC-EVALB-SC/HSC-ADC-EVALB-DC
The SPI interface designed on the Cypress IC can communicate
with up to five different SPI-enabled devices. The CLK and data
lines are common to all SPI devices. The correct device is
chosen to communicate by using one of the five active low chip
select pins. This functionality is controlled by selecting a SPI
channel in the software.
CLOCKING WITH INTERLEAVED DATA
ADCs with very high data rates can exceed the capability of a
single buffer memory channel (~133 MSPS). These converters
often demultiplex the data into two channels to reduce the rate
required to capture the data. In these applications, ADC Analyzer
must interleave the data from both channels to process it as a
single channel. The user can configure the software to process
the first sample from Channel A, the second from Channel B,
and so on, or vice versa. The synchronization circuit included in
the buffer memory forces a small delay between the write enable
signals (WENA and WENB) to the FIFO memory chips (Pin 1,
U101, and U201), ensuring that the data is captured in one
FIFO before the other. Jumper J401 and Jumper J402 determine
which FIFO receives WENA and which FIFO receives WENB.
CONNECTING TO THE HSC-ADC-FPGA-4/-8
ADCs that have serial LVDS outputs require another board that
is connected between the ADC evaluation board and the FIFO
data capture card. This board converts the serial data into
parallel CMOS so that the FIFO data capture card can accept
the data. For more detailed information on this board, refer to
the HSC-ADC-FPGA datasheet at www.analog.com/hsc-FIFO.
CONNECTING TO THE DEMUX BRD
ADCs that have parallel LVDS outputs require another board
that is connected between the ADC evaluation board and the
FIFO data capture card. This board converts parallel LVDS to
parallel CMOS, using both channels of the FIFO data capture
card. For more detailed information on this board, send an
email to [email protected]
UPGRADING FIFO MEMORY
The FIFO evaluation board includes one or two 32 kB FIFOs
that are capable of 133 MHz clock signals, depending on the
model number. Pin-compatible FIFO upgrades are available
from IDT. See Table 2 for the IDT part number matrix.

DEFAULT SETTINGS
Table 5 lists the default settings for each model of the FIFO evaluation kit. The single channel (SC) model is configured to work with a
single channel ADC using the bottom FIFO, U201. The dual channel (DC) model is configured to work with demultiplexed ADCs (such
as the AD9430). Dual channel ADC settings are shown in a separate column, as are settings for the opposite (top) FIFO, U101 for a single
channel ADC. To align the timing properly, some evaluation boards require modifications to these settings. Refer to the Clocking
Description section in the Theory of Operation section for more information.
Another useful way to configure the jumper settings easily for various configurations is to consult ADC Analyzer under Help > About
HSC_ADC_EVALB, and click Set Up Default Jumper Wizard. Then click the configuration setting that applies to the application of
interest. A picture of the FIFO board is displayed for that application with a visual of the correct jumper settings already in place.

HSC-ADC-EVALB-SC/HSC-ADC-EVALB-DC
EVALUATION BOARD
The FIFO provides all of the support circuitry required to
accept two channels of an ADC’s digital parallel CMOS outputs.
Each of the various functions and configurations can be selected by
proper connection of various jumpers (see Table 5). When
using this in conjunction with an ADC evaluation board, it is
critical that the signal sources used for the analog input and
clock have very low phase noise (<1 ps rms jitter) to realize the
ultimate performance of the converter. Proper filtering of the
analog input signal to remove harmonics and lower the integrated
or broadband noise at the input is also necessary to achieve the
specified noise performance.
When operating the evaluation board in a non-default
condition, J316 can be removed to disconnect the switching
power supply. This enables the user to bias the board
independently. Use P302 to connect an independent supply to
the board. A 3.3 V supply is needed with at least a 1 A current
capability.
CONNECTION AND SETUP
The FIFO board has a 120-pin (40-pin, triple row) connector
that accepts two 16-bit channels of parallel CMOS inputs (see
Figure 6). For those ADC evaluation boards that have only an
80-pin (40-pin, double row) connector, it is pertinent for the
lower two rows of the FIFO’s triple row connector to be connected
in order for the data to pass to either FIFO channel correctly.
The top or third row is used to pass SPI signals across to the
adjacent ADC evaluation board that supports this feature.
See Figure 5 to Figure 15 for complete schematics and layout plots.
POWER SUPPLIES
The FIFO board is supplied with a wall mount switching power
supply that provides a 6 V, 2 A maximum output. Connect the
supply to the rated 100 ac to 240 ac wall outlet at 47 Hz to 63 Hz.
The other end is a 2.1 mm inner diameter jack that connects to
the PCB at J301. On the PC board, the 6 V supply is then fused
and conditioned before connecting to the low dropout 3.3 V
linear regulator that supplies the proper bias to the entire board.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
