This document serves as a user's guide for the ADS58H40 Evaluation Module (EVM). The EVM provides
a platform for evaluating the ADS58H40, a quad-channel, 14-bit telecommunications analog-to-digital
converter (ADC) operating at sampling rates of up to 250 MSPS. Designed for low-power consumption
and high spurious free dynamic range (SFDR), the ADC has low-noise performance and outstanding
SFDR over a large input-frequency range.
The four ADC channels are separated into two blocks with two ADCs each. Each block can individually be
configured into three different operating modes: 11-bit Operating mode, 11-bit SNRBoost mode, 14-bit
High Resolution Burst mode.
This EVM is ideally suited for mating with the TSW1400 Capture Card for performing a data capture into a
capture buffer, uploading the sample data to a PC, performing an FFT, and reporting on SNR, SFDR, and
other performance metrics.

Page 3: Evm Power Supply
ADS58H40. Power to the EVM is typically supplied by a single 6-V power brick. Banana jacks may also be used to supply power to the EVM. All necessary voltages for the ADS58H40 are derived from the 6-V input connection. -
Page 4: Evm Connectors And Jumpers
RESET ADS58H40 CH B CLKIN Figure 3. ADS58H40 EVM Connector and Jumper Locations The locations of the connectors, jumpers, pushbutton switches, and LEDs are shown in Figure 3. The EVM has power connectors or banana jacks connecting the main power for power distribution. The SMA connectors connect the ADC input and ADC clock input to the ADC. - Page 5 If the ADS58H40 is configured for high resolution burst mode, pressing SW2 while JP12 is set to the 2-3 position allows the ADC to enter burst mode. The SW2 pushbutton also provides the initial pulse needed to start the auto-burst mode process after the ADC is configured in High Resolution Auto-Burst mode.

LED D1 is lit indicating the presence of the 6-V supply voltage to the EVM, while LED D2 is lit indicating the presence of the USB to serial converter power. LEDs D3 and D4 indicate the status of the ADS58H40 High Resolution Burst Mode. -
Page 7: Software Control
The software allows programming control of the ADS58H40 device. The front panel provides a tab for common control of the ADS58H40 and a SNRBoost/Burst Mode tab for control of the special data capture modes. The GUI tabs provide a convenient and simplified interface to the most-used registers of each device. -
