3 Basic Test Setup
This section outlines basic testing of the ADS54J54EVM.
3.1 Test Block Diagram
The test setup for the ADS54J54EVM is shown in Figure 10 . The TSW14J56 Capture Card is used to
capture data from the ADS54J54 EVM, which is then transferred to the computer for analysis in the HSDC
Pro software. The analog signal into a channel of the ADS54J54 can be from any high-quality low-jitter
analog signal source. The clock source is from the LMK04828, but the board provides an option to use an
external clock source, such as a HP8644B for the ADC sample clock. Note that a narrow bandpass filter is
recommended on the analog source, which is necessary to remove as much phase noise from the signal
source so as to achieve the best performance. The performance can be increased using external clock
mode as this allows for the use of a filter on the clock source.
