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 Highlights

  1. Integrated 14-bit, 92.16 MSPS ADC
  2. T/H (track-and-hold amplifier) analog input for excellent IF sampling up to 200MHz
  3. Six Independent Digital Filtering Channels
  4. RMS/Peak power monitoring of the ADC data port and 96dB range AGCs before the output ports
  5. Three programmable RAM coefficient filters, three halfband filters, two fixed coefficient filters, and one 5th order CIC filter per channel
  6. Complex filtering by combining filtering capability of multiple channels
  7. Three 16-bit Parallel output ports operating at up to 200MHz clock
  8. Blackfin® and TigerSHARC® compatible 8/16-bit Microprocessor port
  9. Synchronous Serial communications port is compatible with most serial interface standards, SPORT, SPI, SSR etc.
