The Data Capture (WV4) Board is connected to a personal computer running WaveVision software through a USB port. The ™ WaveVision4 software runs on Microsoft Windows and the latest version can be downloaded from the web at http://www.national.com/adc. 1.0 Introduction The ADC128S102EVAL Design Kit (consisting of the ADC128S102 Evaluation Board and this User's Guide) is designed to ease evaluation and design-in of National Semiconductor’s eight-channel, low-power CMOS Analog-to-Digital Converters (ADC128S102, ADC108S102, ADC088S102, ADC128S052, ADC108S052, ADC088S052, ADC128S022, ADC108S022, and ADC088S022). This family of pincompatible ADCs will be referenced throughout this document as the ADC128S102. Note: WaveVision Software version 4.2 or later is required to evaluate this part with the WV4 Evaluation System. The Analog input signal enters the Analog-to-Digital Converter through one of its eight selectable input channels and is converted into a digital stream of bits by U1, the ADC128S102. The WV4 system captures and displays the digitized signal on a PC monitor in the time and frequency domains. The evaluation board can be used in one of two modes; Stand-alone or Computer mode. In Stand-alone mode, suitable test equipment, such as a function generator and logic analyzer, can be used with the board to evaluate the ADC128S102. The software will perform an FFT on the captured data upon command. This FFT plot shows dynamic performance in the form of SNR, SINAD, THD, SFDR and ENOB. A histogram of the captured data is also available. In the Computer mode, data capture and evaluation is simplified by connecting this board to National Semiconductor's Data Capture Board (order number WAVEVSN BRD 4.0) with a 14-pin ribbon cable (order J2 IN A JP2 JP1 J4 IN B U1 ADC128S102 J3 Serial Interface WV4 Connector JP3 D3 JP7 Clk Selection JP8 J5 +5V In JP6 JP9 D1 J6 External Clock Figure 1: Component and Test Point Locations 4 http://www.national.com 2.0 Board Assembly 2 1 The ADC128S102 evaluation board comes fully assembled and ready for use.

Finally, import the Data taken with a Logic Analyzer or other third-party equipment into the WaveVision4 Software. Refer to WaveVision4 Manual for data analysis techniques. 3.2 Computer Mode Refer to Figure 1 for locations of test points and major components. 1. 2. Table 1: Quick Start Jumper Configuration 2. 14 13 The ADC128S102 evaluation board may be used in the Stand-Alone mode to capture data with a logic analyzer or other third-party equipment. It may also be used in the Computer Mode with a WV4 Board. In both cases, the captured data can be analyzed with National Semiconductor’s WaveVision4 software. Connect a clean analog (not switching) +5V power source to Power Connector J5. Connect a single-ended source of 4.8 VP-P amplitude from a suitable 50-Ohm source to INB (BNC J4). This signal should be applied through a bandpass filter to eliminate the noise and harmonics commonly associated with signal sources. To accurately evaluate the performance of the ADC128S102, the source must be better than 90dB THD. Note: For a time-varying DC input signal, DC couple the input by placing the jumper at JP3 across pins 1 & 2 instead of pins 2 & 3. The digital inputs and outputs are available at header J3. Refer to Figure 2 for connection details. The source used to create signals SCLK, CSB, and DIN must meet the digital input characteristics in the ADC128S102 datasheet. 2. 3. 4. 5. 6. 5 Run the WaveVision4 program. While the program is loading, continue below. Install the appropriate crystal oscillator into socket Y2 and short pins 1 & 2 of JP7 (See Table 1). Alternatively, connect a low-jitter square wave generator with an amplitude between 2.5 VP-P and 5 VP-P to BNC connector J6 and short pins 2 & 3 of JP7. If using an external source, remove the oscillator from Y2. If using an oscillator at Y2, remove the signal source from J6. The presence of a second oscillator source could add noise to the conversion process. Perform steps 1 and 2 of section 3.1. Connect the 14-pin ribbon cable between J3 of the ADC128S102 evaluation board and J3 of the WV4 board. Connect a clean analog (not switching) +5V power source to Power Connector J1 on the WV4 board. Connect a USB cable between the WaveVision4 Data Capture Board and the PC running the WaveVision4 program. See Section 4.5 for detailed Power Supply Information. Refer to section 5.0 on Software Operation and Settings. http://www.national.com ADC128S102 input channels. For example, to route INA to input channels 0 and 5, close dip switches 1 and 6. For INB, simply place jumpers across JP2 to select input channels. For example, to route INB to input channels 0 and 3, short pins 1 and 2 as well as pins 7 and 8 of JP2. 4.0 Functional Description Table 2 describes the function of the various jumpers on the ADC128S102 evaluation board. The Evaluation Board schematic is shown in Figure 3. Jumper Function DIP1 Routes INA to each of the eight ADC channels. E.g. Switch 1 routes INA to channel 0 while switch 4 routes INA to channel 3. JP1 JP2 JP3 Pins 1 & 2 Pins 3 & 4 Pins 5 & 6 DC couple INA AC couple INA Ground INA JP7 JP8 JP9 The ADC128S102 family gets its reference voltage from the analog supply (VA). Hence, a clean analog supply must be used to guarantee the performance of the ADC128S102. 4.3 ADC Clock Circuit In Computer mode, the ADC128S102 Evaluation board sends a clock signal to the WV4 Data capture board. This clock signal is used to derive the digital signals that drive the ADC128S102. Routes INB to each of the eight ADC channels. E.g. Pins 1 & 2 route INB to channel 0 while pins 15 and 16 route INB to channel 7. Pins 1& 2 Pins 2 & 3 DC couple INB AC couple INB JP5 JP6 4.2 ADC Reference Circuitry The crystal-based oscillator provided on the evaluation board is selected by shorting pins 1 & 2 of JP7. It is best to remove any external signal generator when using this oscillator to reduce any unnecessary noise. This board will also accept a clock signal from an external source by connecting that source to BNC J6 and shorting pins 2 & 3 of JP7. An ac-coupling circuit together with a DC-biased resistive divider is provided so the board can accept a 50 Ohm signal source in the range of 2.5 to 5.0VP-P to drive this input. It is best to remove the oscillator at Y2 when using an external clock source to reduce any unnecessary noise. Not Used Pins 1& 2 Pins 2 & 3 5P5V_REMOTE 5P5V_LOCAL Pins 1& 2 Pins 2 & 3 Select on-board clock oscillator Y2 Select clock oscillator at BNC J6 Pins 1& 2 Pins 2 & 3 Select on-board +3.3V Select +3.3V from WV4S board Pins 1& 2 Pins 2 & 3 Not Used Set VD=VA If the Evaluation board is used in Stand-alone mode, the onboard oscillator and signal applied to J6 do not drive the SCLK pin. Rather, an external source such as a pattern generator must supply the digital signals (CSB, SCLK, DIN) to drive the ADC128S102. These signals must be applied at J3, the Serial Interface Header (See Figure 2). Note: SCLK, CSB, & DIN must be driven between 0 and VA to prevent damage to the ADC. Table 2: Jumper Functions 4.4 Digital Data Output 4.1 The Signal Input The serial data output from this board may be monitored at TP15 or J3. Note: The TP15 test points are current limited by 1kΩ resistors which will cause some slewing of the digital waveforms. For data capture with the WaveVision4 Software, refer to section 3.2. Detailed timing diagrams can be found in the datasheet. The input signal to be digitized can be applied through the BNC connector at J2 (INA) or J4 (INB). Two inputs allow the user to utilize multiple channels of the eightchannel ADC128S102 at the same time. Both INA and INB can be AC coupled or DC coupled. To digitize a time-varying DC signal, place a jumper across pins 1 and 2 of JP1 for INA, or place a jumper across pins 1 and 2 of JP3 for INB. If the AC component of an input signal is to be evaluated, place a jumper across pins 3 and 4 of JP1 for INA, or place a jumper across pins 2 and 3 of JP3 for INB. Additionally, INA can be grounded by shorting pins 5 and 6 of JP1. 4.5 Power Supply Connections The ADC128S102 Evaluation Board has three independent supplies; VA, VD, and 3P3V. VA serves as the analog reference for the Analog to Digital Converter and must be driven by a clean source to maximize the performance of the ADC128S102. The voltage applied to VA can be any value between 2.7V and 5.25V. VD sets the digital output level of the device and can be any value between 2.7V and the voltage applied to pin VA. 3P3V supplies power to the on-board EEPROM Both INA and INB of the ADC128S102 Evaluation board can be routed to any number of the Analog-to-Digital converter’s eight channels. For INA, simply close the DIP switches corresponding to the desired 6 http://www.national.com and is automatically generated on the evaluation board when pins 1 & 2 are shorted on JP8. This voltage is only used by U2 when operating the evaluation board in computer mode. A plot of the selected number of samples will be displayed. Make sure there is no clipping of data samples. The Samples may be further analyzed by clicking on the magnifying glass icon, then clicking and dragging across a specific area of the plot for better data inspection. See the WaveVision4 Board User's Guide for details. If desired, VD and VA can be tied together by placing a jumper across pins 2 and 3 of JP9. Otherwise, VD can be driven independently of VA by removing the jumper at JP9 and driving pin 2 of JP9 directly. In either case, the supply voltage for VA must be supplied to connector J5, labeled 5P5V, or directly to TP10. A jumper must be placed across pins 1 and 2 of JP6. To view an FFT of the data captured, click on the ‘FFT’ tab. This plot may also be zoomed in on. A display of dynamic performance parameters in the form of SINAD, SNR, THD, SFDR and ENOB will be displayed at the top right hand corner of the FFT plot. To view a Histogram of the data, click on the “Software Histogram” tab. This plot may be zoomed in on like the data plot. If the input signal is clipping, the ‘zero’ and ‘full-scale’ codes will be very abundant. The number of missing codes will be displayed at the top right hand corner of the plot. 5.0 Software Operation and Settings The WaveVision4 software is included with the WV4 board and the latest version can be downloaded for free from National's web site at http://www.national.com/adc.
