TSA1203
Application information
23/30
Caution:
Do not use the VB3 power supply (5 V) dedicated to the 74LCX573 external buffers to
supply the VB2 of the TSA1203 which cannot exceed 3.3 V.
8.7.2
Consumption adjustment
Before beginning characterization tests, make sure to adjust the Rpol (Raj1), and therefore
Ipol value, according to your sampling frequency.
8.7.3
Single and differential inputs
The test board can be driven on a single analog input, or on differential inputs. With a single
analog input, you must use the ADT1-1WT transformer to generate a differential signal. In
this configuration, the resistors RSI6, RSI7, RSI8 for channel I (respectively RSQ6, RSQ7,
RSQ8 for channel Q) are connected as short-circuits whereas RSI5, RSI9 (respectively
RSQ5, RSQ9 for channel Q) are open circuits.
Alternatively, you can use the JI1 and JI1B differential inputs. In this case, the resistances
RSI5, RSI9 for channel I (respectively RSQ5, RSQ9 for channel Q) are connected as short-
circuits whereas RSI6, RSI7, RSI8 (respectively RSQ6, RSQ7, RSQ8 for channel Q) are
open circuits.
8.7.4
Mode selection
In order to select the channel you want to evaluate, you must set a jumper on the board in
the relevant position for the SELECT pin (see Figure 31).
The channels selected depend on the position of the jumper:
●
With the jumper connected to the upper connectors, channel I at the output is selected.
●
With the jumper connected horizontally, channel Q at the output is selected.
●
With the jumper connected to the lower connectors, both channels are selected,
relative to the clock edge.
