DESCRIPTION (Continued) The CFR blockreducesthepeak-to-averageratio(PAR) ofthedigitaltransmitsignals,such as thoseused in third-generation(3G) code divisionmultipleaccess (CDMA) and orthogonalfrequency-divisionmultiple-access (OFDMA) applications. The DPD pathwitha 310-MHz DPD clockcan be configuredtosupportone antennaat62 MHz, two antennasat 62 MHz each,or fourantennasat 31 MHz each,allwithan associated5× DPD expansionbandwidth.The GC533x DPD processorreduces power amplifier(PA) nonlinearity,e.g.,as measured by adjacent-channel leakageratio(ACLR), by over 20 dB. By reducingthe PAR of the digitalsignaland the PA nonlinearity,the operationalefficiencyoffollow-onpower amplifierscan be substantiallyimproved.

CrestFactorReduction (CFR) The CFR blocksincludetheCFR functionand two interpolate-by-2filters(referredtohere as UC1 and UC2). The two CFR blockstogethercan support1, 2, or 4 TX streams.The CFR functionselectivelyreducesthe peak-to-averageratio(PAR) ofwideband digitalsignalsprovidedinquadrature(Iand Q) format,such as those used in3G and 4G wirelessapplications.For example,theCFR functioncan reducethePAR ofWCDMA Test Model 1 signalsto5.7dB, whilestillmeetingall3GPP requirementsforACLR, compositeEVM, and peak code domain error(PCDE). The CFR blockscan be configuredinelevendifferentmodes, dependingon thenumber ofTX streams,theDPD mode, and the signalsample rates.Relativeto previousTI CFR products,the GC533x CFR has enhanced featuressuch as:
- ConstantPAR mode
- Constantinput-to-outputpower mode
- Dynamic PAR targetlevelsfordifferentportionsofthetime-domainsignal
- Up to25% lesslatencyforcertainconfigurations
- Enhanced CFR performancefornarrowbandsignals
- Automatic(i.e.,no hostinteractionrequired)CFR coefficientgenerationforfrequency-hoppingsignals The UC1 and UC2 blockscan be setto1× or2× interpolationand may be used toprovideoptimum selectionof signaloversamplingratioatCFR. UC1 may be positionedbeforeoraftertheCFR function,whileUC2 isalways at the outputof CFR. Since UC2 has onlya 40% bandwidthimage rejection(90 dB) filter,itisonlyused if precededby UC1, whichhas an 80% bandwidthimage-rejection(90dB) filter. DigitalPredistortion(DPD) The DPD blocksincludethe DPD function,TX equalization,and the envelope tracking(ET) function.The GC533x supportstwo modes ofoperation,dependingon signalbandwidthand desiredDPD correctioncapability: high-performance(HP) mode and high-bandwidth(HB) mode.

- DPD HP mode input (Referredtoas node A)
- DPD HP mode output (Node B)
- DPD HB mode input (Node C)
- DPD HB mode output (Node D)
- RX AB input (Node E)
- RX path0/1output (Node F)
- RX C (feedback)input (Node G)
- Testbus The capturebufferscan be triggeredvia an externalsync signal,througha softwaretrigger,or when the monitoredsignalexceeds theuser-configurablethresholds.The capturebufferscan be programmed tomonitor the signalstatisticscontinuouslyand only capturedata when certainrequirementsare met, as wellas to generatean interruptwhen a qualifiedbufferiscaptured.Thishelpsinselectingan optimum setofdataforthe DSP to use in optimizingthe DPD coefficients.The capturebufferscan be read by the DSP viathe MPU interface. The capturebuffersalsoallowsynchronizedmulti-chipdata capture.For a multipleantenna system thatuses more thanone GC533x, a feedbacksignaltouse inadaptingDPD coefficientsinmultipleGC533x chipscan be connectedtojustone oftheGC533x chips.The SYNCOUT signalcan be used todaisy-chain(e.g.,connecting toSYNCA on thenextchip)acrosstheGC533x chipsinthesystem.The SYNCOUT signalindicatestheend of thedatacaptureand can be used as a capturetriggerinallchips. Microprocessor(MPU) Interface The MPU interfaceisdesignedtointerfacewithexternalmemory interface(EMIF)portson TIDSPs operatingin asynchronousmode. Itconsistsofa 16-bitbidirectionaldatabus,an 8-bitaddressbus,and WEB, OEB, CEB, and EMIFENA controlsignals.The interfacesupportsthe TI ‘C6748 as an EMIF asynchronousinterface.The MPU interfacehas two addressspaces:a paged addressspace and an auto-incrementaddressspace. To enabletheEMIF interface,pinEMIFENA must be settologichigh. In an MPU writecycle,a GC533x internalMPUCLK signalis generatedby NORing CEB and WEB. The MPUCLK signalgoes highwhen bothCEB and WEB areassertedand goes low as soon as eitherCEB orWEB isde-asserted.The MPU data islatchedon the risingedge of the MPUCLK signal.For the auto-increment addressspaces,theauto-incrementaddressincrementson thefallingedge oftheMPUCLK signal. Inan MPU readcycle,a GC533x internalMPUCLK signalisgeneratedby NORing CEB and OEB.
