Quick View of Evaluation Setup
Figure 1 shows an overview of the evaluation setup that includes the ADS5295EVM evaluation module
(EVM), TSW1400EVM, external equipment, personal computer (PC), and software requirements.
Figure 1. Evaluation Setup
TSW1400EVM/GUI: The high-speed LVDS deserializer board, TSW1400EVM, is required for capturing
data from the EVM. The capture analysis uses the TSW1400 High Speed Data Converter Pro graphical
user interface (GUI). For more information pertaining to the TSW1400EVM, see:
http://focus.ti.com/docs/toolsw/folders/print/tsw1400evm.html
Equipment: Signal generators (with low-phase noise) must be used as the source of input signal and
clock (optional) in order to get the desired performance. Additionally, band-pass filters (BPF) are required
in signal and clock (optional) paths to attenuate the harmonics and noise from the generators.
Power Supply: A single +5-V supply powers the EVM. The supplies for the ADS5295 device are derived
from the +5-V supply. The power supply must be able to source up to 1.5 A. A +5-V wall adapter supply
powers the TSW1400EVM.
USB Interface to PC: The USB connection from the EVM and TSW1400EVM to the personal computer
(PC) must be set up.
ADS5295GUI: Section 3.1 explains the GUI installation procedure and its operation.

Connect Channel 1 of the ADS5295EVM to a signal generator through a band-pass filter (BPF). If no
BPF is present, the results are not good.
The amplitude of the input signal is dependent on the insertion loss of the filter and cables used as
well as the desired backoff from full-scale. An iterative approach is used to determine the amplitude
setting required to operate at approximately -1.0 dBFS. In this test setup, the amplitude was set to
+18.4 dBm.
Set the frequency of the signal generator to that shown in the ADC Input Target Frequency box
(1.00219727M).
Change the window option to Hanning, due to the fact that input signal and onboard CMOS clock are
non-coherent.
Pressing the Capture button returns the test result.
Repeat for Channels 2 through 8.
