1.2 Board ConfigurationDemonstration Kit Configuration Options

The analog quadrature modulator requires a common-mode DC voltage of approximately 3.3V. In order touse the dc-offset adjustment capabilities of the DAC5682 for carrier suppression, it is imperative tomaintain a dc path from the DAC output to the modulator input. The common-mode voltage for themodulator is maintained with a passive resistor network that is designed to provide the proper operationpoint for the DAC5682 and the TRF3703 modulator. By design, in order to preserve the proper dc levels,the DAC coarse gain should be kept at the maximum (15), though deviation by a few steps is generallyacceptable with no degradation in performance.

The resistor network can be configured such that the DAC output is routed to a transformer which definesthe board as a DAC5682z EVM or routed to the TRF3703 which results in the TSW3082 EVM.

2.1 System Block Diagram

Block Diagrams

The CDCM7005 requires a VCXO or external clock source to derive its output clock signals. The VCXO isat reference designator U6. This TSW3082 and DAC5682z EVM release does not have a VCXO andrequires an external clock source on SMA J6. The VCXO can be changed to operate the Demo Kit withdifferent clocking schemes for different modulation standards or for specific customer requirements. Usethe VCXO or external clock frequency to properly configure the CDCM7005 (see Section 2 of Figure 15).

These conventions are typically used:• WCDMA—derivatives of 61.44 MHz• GSM—derivatives of 52 MHz• CDMA2K—derivatives of 78.6432 MHz• WiMAX—derivatives of 112 MHz

The TSW3082 requires an external Local Oscillator (LO) source to drive the on board TRF3703-33modulator. This external LO input can be connected at SMA connector J23. The signal level of the LOsource should comply with the requirements in the TRF3703 data sheet (SLWS184), but typically an LOpower around 0 to 3 dBm is adequate.

The basic radio system block diagram in Figure 3 demonstrates where the TSW3082 Demo Kit fits in theoverall transceiver. The dash-line box illustrates the components found on the TSW3082 Demo Kit board.

Key Texas Instruments Components

The CDCM7005 clock distribution chip is used to generate and synchronize the clock outputs to thesystem. The device has five outputs which can be either LVPECL or LVCMOS, and can be divided downby 1, 2, 3, 4, 6, 8, and 16. The divide by 16 can be replaced with a divide by 4 or 8 with a 90 degreephase shift. See the CDCM7005 data sheet (SCAS793) for more information.

The DAC5682 is a 16-bit interpolating dual digital-to-analog converter (DAC) with a high speed LVDS datainterface. The device incorporates a digital complex coarse mixer, independent differential offset control,and I/Q amplitude control. The device can be used with excellent results in baseband mode, low IF mode,as well as in high IF mode with an analog quadrature modulator. See the DAC5682 data sheet (SLLS853)for more information.

The TRF3703 is a direct upconversion (DUC) IQ modulator. This device accepts a differential inputvoltage quadrature signal at baseband or low IF frequencies and outputs a modulated RF signal based onthe LO drive frequency. See the TRF3703 data sheet (SLWS184) for more information.

The enclosed CD-ROM contains all of the necessary software needed for the host PC to control theDAC5682Zz and CDCM7005. The interface software is a Graphical User Interface (GUI) that can programall the registers in the CDCM7005 and the DAC5682z. Once the software is installed, the GUI isaccessible from the Start → All Programs → Texas Instruments DACs → DAC5682z EVM Control.

Demo Kit Test Configuration

The test setup for the TSW3082 and DAC5682z EVM is shown in Figure 17. This setup shows theTSW3100 pattern generator supplying an LVDS signal to the TSW3082/DAC5682 EVM.

Figure 17. TSW3082 EVM Driven by TSW3100 Pattern Generator

This test equipment is required for testing the TSW3082 and DAC5682 EVM. Other equipment may besubstituted, however results may vary due to instrument limitations.• Power supplies—1.8 V (DAC digital), 3.3 V (DAC analog), and 5 V (RF modulator)• Spectrum Analyzer—Rhode & Schwarz FSU, FSQ, or equivalent. This is necessary to measure the

noise floor ACPR greater than 70 dBm with the noise correction option.• Pattern generator—TSW3100 using LVDS mode, or some other LVDS capable generator.• Oscilloscope—probe clock and data lines for troubleshooting.• Digital volt meter—verify signal levels.

To measure the proper output power, the insertion loss of the analyzer cable must be calibrated. Measurea calibrated 0 dBm source to see how much loss is in the cable at the frequency of interest.

The DAC5682 EVM measurements at the transformer outputs J1 and J3 (modulator is not used) will havebetter performance than the RF output. The RF output is typically limited by the performance of the RFparts. In this case the DAC output at 0 IF or low IF is several dB better than the noise floor of themodulator output at J16.

8.2 Engage Power Supplies

8.3 Verify the Status of the Board

8.4 Program the CDCM7005

Initial Power Up and Test

Figure 19. TSW3082 EVM output at RF LO + low IF of 30.72M (6 dB lower than DAC output)

This section outlines the basic power application and test procedure to ensure the EVM is in anoperational state.

Inspect the board to determine which VCXO resides on the board. This is useful when programming theCDCM7005 to lock the DAC clock to the reference.

Engage the power supplies for 1.8 V, 3.3 V, and 5 V. Ensure that each supply is not drawing more than1 A of current. Typically the 1.8 V will be less than 1 A, 3.3 V less than 200 mA, and 5 V less than 0.5 A.

The DAC software detects if the USB port is active and if it is capable of reading the serial number fromthe EVM. This determines if the communication between the board and PC is correct. The EVM Homemenu (Figure 13 and Table 3) of the DAC8652z GUI software provides this status information.

Navigate to the Register Config menu (Figure 15 and Table 5). Program the CDCM7005 registers asnecessary. Typically a reg.cdcm7005 register file is provided to initialize the default settings. Load thisregister file using the section 4 (SEND/SAVE Button Settings) controls described in Table 5 .

8.5 Program the DAC5682z

8.6 Carrier Suppression

9 Optional Configurations

9.1 External VCXO

9.2 RF or DAC Output

Optional Configurations

Navigate to the DAC5682 Diagram menu (Figure 14 and Table 4 ). Adjust the register settings as desired.Typically a reg.dac5682 register file provides a set of test register values. Load this register file using thesection 8 (SEND/SAVE Button Settings) controls described in Table 4 .

Carrier feed through is dependent on the DC offset between I and Q paths. There are registers in the DACthat provided some digital DC correction. A feedback path is necessary to perform this correction. Contactthe TI factory applications team for more details.

It is possible to configure the TSW3082 and DAC5682 EVM to use an external VCXO for applicationflexibility. J13 and J14 may be used in position 2-3 to select an external VCXO or clock signal.

The board is populated with the TRF3703 modulator. If the board is configured for DAC output, themodulator is not used and 5 V power is unnecessary. The DAC outputs in this setup are J1 and J3.

If the board is configured for RF output, the 5 V must be used to power the modulator. The resistor path atthe output of the DAC must be changed to pass the signal to the modulator instead of to the transformers.In this case an external LO must be provided on J23 and the RF output is present at J16.

10 Baseband Filter

10.1 RF Output Matching Filter

Baseband Filter

The TSW3082 EVM is configured with enough pads to provide a customer a specific 5th-order differentialpassive LC filter. By default, it is only populated with a simple LC low pass filter to attenuate the higherclock harmonics. The 3 dB corner of this filter is approximately 300 MHz.

Figure 20. Response of Default Baseband Filter

The TSW3082 RF output provides a pi pad network on the modulator output to provide some matching orfiltering if desired. In its default state the pad is not used and a series cap is used on the RF output.
