Description

The AD6654 is a mixed-signal IF to base band receiver consisting of a 14-bit, 92.16 MSPS analog-to-digital converter (ADC) and a four/six channel, multi-mode digital down converter (DDC) capable of processing up to six WCDMA (Wideband Code Division Multiple Access) channels. It has been optimized for the demanding filtering requirements of wideband standards such as CDMA2000, UMTS, and TD-SCDMA. The AD6654 is used as part of a radio system that digitally demodulates and filters IF sampled signals.PRODUCT HIGHLIGHTSIntegrated 14-bit, 92.16 MSPS ADCT/H (track-and-hold amplifier) analog input for excellent IF sampling up to 200MHzSix Independent Digital Filtering ChannelsRMS/Peak power monitoring of the ADC data port and 96dB range AGCs before the output portsThree programmable RAM coefficient filters, three half-band filters, two fixed coefficient filters, and one 5th order CIC filter per channelComplex filtering by combining filtering capability of multiple channelsThree 16-bit Parallel output ports operating at up to 200MHz clockBlackfin®and TigerSHARC®compatible 8/16-bit Microprocessor portSynchronous Serial communications port is compatible with most serial interface standards, SPORT, SPI, SSR etc.APPLICATIONSMulticarrier, multimode digital receiversGSM, EDGE, PHS, UMTS, WCDMA, CDMA2000, TD-SCDMA, WiMAXMicro and pico cell systems, software radiosWireless local loopSmart antenna systemsIn-building wireless telephonyBroadband data applicationsInstrumentation and test equipment
