THS1040/41EVM Operational Procedure
The THS1040/41EVM provides a flexible means of evaluating the THS1040
and THS1041 in a number of modes of operation. These are described more
fully in Chapter 4. The following basic setup procedure can be used as a board-
confidence check:
Verify all jumper settings against the following schematic jumper table:

Connect supplies to the EVM as follows:
3.3 V analog supply to J8 and return to J7.
3.3 V digital supply to J10 and return to J11.
Switch power supplies on.
Use a function generator with 50-
output to input a 40-MHz, 1.5-V offset,
3-Vp-p amplitude square wave signal into J4 to be used as the ADC clock.
The frequency of the clock must be within the specification for the device
speed grade.
Use a function generator with 50-
output to input a 40-MHz, 1.5-V offset,
3-Vp-p amplitude square wave signal into J14 to be used as the buffered
output clock and the PLD input clock (THS1041 EVM only). This signal
must be the same frequency and synchronized with the ADC clock.
Use a frequency generator with 50-
output to input a 1.5-MHz, 0-V offset,
1.5-Vp-p amplitude sine wave signal into analog input SMA J2. This
provides a transformer coupled differential signal to the ADC.
The digital pattern on the output connector J12 should now represent a
sine wave and can be monitored using a logic analyzer.
