Applying Power And Signals to the DC1532
Demonstration Circuit

The DC1371 is used to acquire data from the DC1532,
the DC1371 must FIRST be connected to a powered USB
port and have 5V applied power BEFORE applying 3.6V to
6.0V across the pins marked V
+
and GND on the DC1532.
DC1532 requires 3.6V for proper operation.
Regulators on the board produce the voltages required
Regulators on the board produce the voltages required
for the ADC. The DC1532 demonstration circuit requires
up to 500mA depending on the sampling rate and the A/D
converter supplied.
The DC1532 should not be removed, or connected to the
The DC1532 should not be removed, or connected to the
DC1371 while power is applied.
Analog Input Network
For optimal distortion and noise performance the RC
For optimal distortion and noise performance the RC
network on the analog inputs may need to be optimized
for different analog input frequencies. For input frequen-
cies above 140MHz, refer to the LTC2268 datasheet for a
proper input network. Other input networks may be more
appropriate for input frequencies less that 5MHz.
In almost all cases, filters will be required on both analog
In almost all cases, filters will be required on both analog
input and encode clock to provide data sheet SNR.
The filters should be located close to the inputs to avoid
The filters should be located close to the inputs to avoid
reflections from impedance discontinuities at the driven
end of a long transmission line. Most filters do not present
50Ω outside the passband. In some cases, 3dB to 10dB
pads may be required to obtain low distortion.
