4.
Connect the analog signal V
IN
. The inverted phase clock input V
INB
may be left
open (as on-board 50
Ω terminated). Use a low phase noise RF source. Full
Scale range is 0.5V peak to peak around 0V, (±250 mV), or –2 dBm into 50
Ω.
Input frequency can range from DC up to 1.8 GHz. At 1.8 GHz, the ADC attenu-
ates by –3 dB the input signal.
5.
Connect the high speed data acquisition system probes to the output connector.
The connector pitch (2.54 mm) is compatible with High Speed Digital Acquisition
System probes. The digital data are on-board differentially terminated. However,
the output data can be picked up either in single-ended or differentially mode.

Board functionality verification and proposed product evaluation procedure:
– A first test can be run at 500 Msps/250 MHz Nyquist: about 7.4 Effective Bits
(typ) should be obtained.
– At 1 Gsps/500 MHz: about 7.0 Effective Bits (typ) should be obtained.
– At 1 Gsps/1 GHz and –1 dB Full Scale analog input, 6.4 bits and -43 dBc
SFDR should be obtained. In the same conditions for –3 dB Full Scale input,
6.8 bits and –48 dBc are obtained.
7.
The devices operate respectively from 10 Msps up to 1.4 Gsps in binary output
format and 10 Msps up to 2 Gsps in Gray output format. It is capable of sampling
analog input waveforms ranging from DC up to 1.5 GHz.

Characteristics
Notes:
1. Absolute maximum ratings are limiting values (referenced to GND = 0V), to be applied individually, while other parameters
are within specified operating conditions. Long exposure to maximum rating may affect device reliability. The use of a ther-
mal heat sink is mandatory.
2. In case only one supply is used for supplying the
–
5V negative power planes, apply the V
EED
absolute maximum ratings.
