Single and Differential Inputs:
The ADC board components are mounted to test
the TSA1005-40 with single analog input; the
ADT1-1WT transformer enables the differential
drive into the converter; in this configuration, the
resistors RSI6, RSI7, RSI8 for I channel (respec-
tively RSQ6, RSQ7, RSQ8 for Q one) are con-
nected as short circuits whereas RSI5, RSI9 (re-
spectively RSQ5, RSQ9) are open circuits.
The other way is to test itvia JI1 and JI1B differen-
tial inputs. So, the resistances RSI5, RSI9 for I
channel (respectively RSQ5, RSQ9 for Q one) are
connected as short circuits whereas RSI6, RSI7,
RSI8 (respectively RSQ6, RSQ7, RSQ8 for Q
one) are open circuits.
Grounding consideration
So as to better reject noise on the board, connect
on the bottom overlay AG (AGND), DG(DGND),
GB1(GNDBI)
together
GB2(GNDBE) with GB3(GNDB3) from the other
part.

Mode select
So as to evaluate a single channel or the dual
ones, you have to connect on the board the
relevant position for the SELECT pin.
With the strap connected:
- to the upper connectors, the I channelat the out-
put is selected.
- horizontally, the Q channel at the output is se-
lected.
- to the lower connectors, both channels are se-
lected, relative to the clock edge.

Consumption adjustment
Before any characterization, care should be taken
to adjust the Rpol (Raj1) and therefore Ipol value
in function of your sampling frequency.
