ADS58H43EVM

User's Guide SLAU455B – August 2012 – Revised May 2016 ADS58H4x (ADS58H40/ADS58H43) EVM This document serves as a user’s guide for the ADS58H4x (ADS58H40/ADS58H43) Evaluation Module (EVM). The EVM provides a platform for evaluating the ADS58H40 or the ADS58H43, 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. For more information regarding the ADS58H4x and the related evaluation tools, please refer to the following: • ADS58H40 – Quad 14-bit 250-MSPS ADC with SNRBoost and Burst Mode (SBAS589) • TSW1400 – High-Speed Data Capture and Pattern Generation Platform (SLWU079) • ADS58H40 EVM Configuration Software (SLAC533). This software is compatible for both ADS58H40 and ADS58H43. 1 2 3 Contents Introduction ................................................................................................................... 2 1.1 EVM Block Diagram ................................................................................................ 2 1.2 EVM Power Supply ................................................................................................. 3 1.3 EVM Connectors and Jumpers ................................................................................... 4 1.4 EVM ADC Input Circuit Configurations .......................................................................... 6 Software Control ............................................................................................................. 7 2.1 Installation Instructions ............................................................................................. 7 2.2 Software Operation ................................................................................................. 7 Basic Test Procedure ...................................................................................................... 10 3.1 Test Block Diagram ............................................................................................... 10 3.2 Test Set-up Connection .......................................................................................... 11 3.3 ADS58H4x Software Quick Start Guide ........................................................................ 11 3.4 ADS58H4x and TSW1400 Setup Guide ....................................................................... 11 List of Figures 1 2 3 4 5 6 7 8 9 10 .............................................................................. 2 Simplified ADS58H4x EVM Power Supply ............................................................................... 3 ADS58H4x EVM Connector and Jumper Locations..................................................................... 4 ADS58H4x ADC Input Circuit .............................................................................................. 6 ADS58H4x Clock Input Circuit ............................................................................................. 6 ADS58H4x Main Panel...................................................................................................... 8 ADS58H4x SNRBoost/Burst Mode Panel ................................................................................ 9 ADS58H4x and TSW1400 Test Setup Block Diagram ................................................................ 10 Select ADS58H40 in the High Speed Converter Pro GUI Program ................................................. 12 Load ADC Firmware Prompt .............................................................................................. 12 Simplified ADS58H4x EVM Block Diagram SLAU455B – August 2012 – Revised May 2016 Submit Documentation Feedback ADS58H4x (ADS58H40/ADS58H43) EVM Copyright © 2012–2016, Texas Instruments Incorporated 1 Introduction 11 12 13 14 www.ti.com ............

The four analog inputs are supplied to the EVM through a single-ended SMA connection, then transformer coupled, turning the single-ended signal into a balanced differential signal, and then input to the ADS58H4x. A dual transformer input circuit provides better phase and amplitude balance of the input signal when compared to the performance delivered by a single transformer input circuit.

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 ADS58H4x are derived from the 6-V input connection. 1.2 EVM Power Supply Figure 2 illustrates the power supply options available on the EVM. Jumpers are used to choose the power supply options, with the default jumper positions indicated by the darker portion of the jumper that represents the presence of the jumper.

The default power path has an efficient dual output DC-DC switching power supply to first step down the input supplies for the low-noise LDOs. The low-noise LDOs generate the 3.3 V and 1.9 V for the ADC power. The low-noise LDOs can be bypassed, allowing the DC/DC power supply to directly power the ADC. In this implementation, adjust the feedback resistors of the DC/DC converter accordingly.

The default setup has a dual 1:1 impedance ratio transformer input circuit, which achieves better phase and amplitude balance of the input signal than is typically produced by a single transformer input circuit. Third-order bandpass filter component pads are available for installing bandpass filter components. The default components for the bandpass filter are either zero Ω or open circuit. The default input termination is 50 Ω, which is formed by two 25-Ω resistors connected to the ADC VCM node. If the user chooses to use 100-Ω termination with the 1:2 impedance transformer, the optional RLR differential arm can be used to tune the in-band flatness. The ADC analog input consists of a switched-capacitor-based, differential sample-and-hold (S/H) architecture. Due to the opening and closing of the sampling glitches, the kick-back noise from the S/H circuit may affect the ADC performance. Besides the on-chip R-C filter of the ADC input, the external RLCR circuit provides additional filtering of the glitches. The default RLCR components have been optimized for input bandwidth centered at 185 MHz. For additional RLCR components of different center frequencies, refer to the ADS58H40 datasheet (SBAS589). 0: 0: 0: DNI 0: 0.1 PF 0: DNI 0: 0.1 PF 3rd Order Bandpass Filter 25 : 25 : 0: VCM DNI Jp Jn 10 : 0: DNI 1:1 0: DNI 1:1 10 pF 25 : 0.1 PF 0.1 PF 10 : 82 nH 14-bit ADC 25 : RLCR Circuit RLR Circuit Figure 4.

As seen in this figure, the evaluation setup involves a clock from a high-quality signal generator and a sine wave for the analog input from a high-quality signal generator. High-order, narrow-bandpass filters are usually required on clock and input frequency to remove phase noise and harmonic content from the input sine waves. If the two signal generators are not synchronized by an external reference signal to make the clock and input frequency coherent, then the resulting FFT first needs a windowing function, such as Hanning or Blackman-Harris, applied to the data.

The cable should be a standard A to mini-B connector cable. 3.3 ADS58H4x Software Quick Start Guide Figure 6 introduced the front panel of the ADS58H4x SPI GUI. This section covers the initial use of the SPI GUI necessary for most evaluations of the ADS58H4x. 1. Press the Reset USB Port button if the USB connection has been disrupted since last use, or if an error message pops up warning that the USB connection is not valid. 2. Use the mouse to select the reset position of the reset switch. This switch is self-clearing. 3. Press Send All to send all the register settings. 4. From this point, select digital functions as desired such as SNRBoost, or set test pattern modes if desired. All register bits listed in the register map of the ADS58H4x data sheet have a switch on the front panel of the SPI GUI for easy configuration of the ADS58H4x. Note that any greyed-out front panel switches are unavailable for use because they have a dependency upon other switch settings, as indicated in the ADS58H4x datasheet. For example, the Channel A Gain selection is unavailable because the default state of the Channel A Gain Enable switch is off. Select the Channel A Gain Enable switch, toggling the switch to the enabled state, and then the Channel A Gain selection becomes available for use. 3.4 ADS58H4x and TSW1400 Setup Guide Reference the TSW1400 User’s Guide (SLWU079A) for more detailed explanations of the TSW1400 setup and operation.
