AFE7225EVM

User's Guide SLOU362 – February 2013 AFE722x Evaluation Module (AFE722xEVM) User's Guide The AFE722x EVM includes a great level of flexibility enabling testing in a more system-like environment. The individual power rails can be generated through LDOs or DC/DC converters from a 6-V power source and the EVM clock architecture allows for external clock input as well as clock generation using a low-jitter PLL in combination with a VCXO. On the transmit side, the EVM provides the option of connecting directly to the DAC outputs or perform up-conversion via an on-board IQ modulator. On the digital side, the EVM provides a seamless interface to the TSW1400 and TSW1405 capture card in order to evaluate received data directly on a PC. The TSW1400 and TSW1406 pattern generation card can be used to provide data to the dual DAC of the AFE722x and the on board, CDCE72010 generates the appropriate clock for the TSW1400 and TSW1406 for synchronous operation. Both the AFE722x and CDCE72010 can be programmed via SPI, conveniently, through the USB connection.

AFE722x EVM Setup 4.1 CDCE72010 Configuration The initial EVM setup is configured so that the AFE722x can be operated at any desired sampling rate. Since the TSW1400 requires an external clock at ¾ of the AFE clock rate (see clocking section) the external clock applied to the CDC AUX IN connector needs to be 3× the AFE sampling rate (that is, 368.64 MHz for 122.88-MHz operation). Loading a preconfigured register file (AUX IN - div3 AFE div4 TSW.txt) to the CDCE72010, it then sets the dividers so that a /3 copy of the input clock is routed to the AFE722x clock input and a /4 copy to the TSW1400. Figure 4. CDCE72010 Configuration 4.2 RX Path Using TSW1400 First the AFE722x digital interface needs to be configured to match the serial LVDS interface that the TSW1400 is expecting. The following control registers need to be set in the General Setup tab of the AFE722x programming software. Also, the USB communication warning sign should be monitored after the USB reset, to ensure proper communication with the AFE722x EVM.

An LDO generates a 5-V rail for the TRF3703 IQ modulator as well as for the low-noise LDOs, which are generating a 3.3-V and 1.8-V rail for the AFE722x and the CDCE72010. Alternatively, the 3.3-V and 1.8-V rails can be generated using DC/DC converters which operate directly from the 6-V input for maximum power efficiency. The EVM provides options to disable unused circuits by means of pin headers. These headers can also be used for accurate power measurements where external power supplies can be directly connected to them. Three pin headers allow a convenient change between powering the AFE722x and CDCE72010 either from a DC/DC converter or low-noise LDO. 6V Input LDO TPS7A4501 JP10 5V TRF3703 I/Q Mod JP19 LDO TPS79633 JP12 3.3V JP18 CDCE72010 JP11 DC/DC TPS62291 6V JP4 VCXO JP14 LDO TPS79518 JP13 1.8V AFE722x JP20 DC/DC TPS62231 Figure 9. Power Supply Jumper Settings 6 Clocking Configuration The AFE722x EVM offers 3 different options for providing the clock to the AFE722x as well as the supporting circuitry. The biggest challenge arises when using the DAC with the TSW1400 because the TSW1400 expects an input clock at 1/8 of the DAC input data rate. However, since the AFE722x is designed for the serial LVDS interface, the DAC data rate is 6x the actual AFE722x clock frequency. Hence, the clock to the TSW1400 needs to 6/8 = 3/4x the AFE722x clock frequency. SLOU362 – February 2013 Submit Documentation Feedback AFE722x Evaluation Module (AFE722xEVM) User's Guide Copyright © 2013, Texas Instruments Incorporated 11 Clocking Configuration www.ti.com The CDCE72010 clock buffer on the AFE722x is used to provide the clock to the TSW1400. Additional dividers can be added to the clock output in order to divide the clock appropriately for optional interpolation by 2x or 4x. Figure 10.

This setup is useful for testing the AFE722x at clock frequencies where a VCXO is not immediately available. 12 AFE722x Evaluation Module (AFE722xEVM) User's Guide Copyright © 2013, Texas Instruments Incorporated SLOU362 – February 2013 Submit Documentation Feedback Clocking Configuration www.ti.com 6.2 System Level In this system configuration on the EVM a VCXO at 6x the desired clock frequency is required – alternatively a different VCXO frequency can be used and the internal CDCE72010 dividers adjusted accordingly. An external reference can be locked to the VCXO for coherency using the CDCE72010. In this configuration the CDCE72010 provides a /6 copy of the VCXO to the AFE722x clock input as well as a /8 copy to the TSW1400. Also, the AFE722x EVM offers a placeholder for a surface mount bandpass filter between the CDCE72010 and AFE722x to limit the clock phase noise. 6.3 AFE722x VCXO CDCE72010 RX Only When testing only the ADCs for maximum performance, the EVM provides an option to connect an external clock directly to the AFE, bypassing the CDCE72010. R74, R76 and R112 need to be modified from their default configuration. The DACs of the AFE can still be operated, however, the TSW1400 can’t be used for data generation as no feedback clock is provided to it. This option provides the lowest possible jitter option when combined with an external bandpass filter. 6.4 RX and TX Independent Clocking The AFE722x supports an option to run the dual ADCs at a different sampling rate than the dual DACs. With a few resistor changes, the clocking circuitry on the AFE722x EVM can be configured to support that feature. However, in this scenario the CDCE72010 is bypassed and no clock is routed back to the TSW1400. Hence an additional clock needs to be provided and the CDCE72010 configured with the appropriate output divider to match the AFE722x DAC clock rate with the data rate from the TSW1400 (see Section 6.1 and Section 6.2). 6.5 SMA R112 R74 Connector 0S 0S CLK IN R76 DNI SMA Connector CLK IN\ R79 DNI R161 0S R78 0S R82 50S T9 C56 DNI CLK INP CLK INN AFE722x 0S 0S Interpolation on the DAC The AFE722x offers 2x and 4x interpolation of the DAC output data. In order to employ interpolation on the DAC, the clock going to the TSW1400 needs to be divided accordingly. For example, interpolation by 2x in the DAC requires that the data coming from the TSW1400 arrives at ½ of the AFE722x clock frequency.

This has no impact on the clock requirements to the AFE722x – it merely reduces the output data rate by a factor of 2x and settings (sampling and input frequency) on the TSW1400 capture card or other data capture tool need to be adjusted accordingly. 7 RX Setup The RX section of the AFE722x is controlled on two separate tabs of the EVM software. In the ‘General Setup’ tab are the control registers for the digital interface such as CMOS or serial LVDS output, for example.

It should not be used as all or part of a finished end product. Your Sole Responsibility and Risk. You acknowledge, represent and agree that: 1. 2. 3. 4. You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees, affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes. You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates, contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to minimize the risk of electrical shock hazard. You will employ reasonable safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even if the EVM should fail to perform as described or expected. You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials. Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in development environments should use these EVMs. Agreement to Defend, Indemnify and Hold Harmless.
