4 / 90 page AD6676 Data Sheet Rev. D | Page 4 of 90 The band-pass Σ-Δ ADC of the AD6676, which operates between 2.0 GHz to 3.2 GHz, provides exceptional instantaneous dynamic range and inherent antialiasing capability. Its in-band frequency response typically maintains better than 1 dB pass band flatness with out-of-band peaking better than 0.5 dB. An integrated digital peak detector enables the instantaneous signal power to be monitored over a wide band (shortly after digitization), thus providing AGC capability to cope quickly with large in-band or out-of-band blockers. The AD6676 includes various AGC monitoring and control features along with an internal 27 dB step attenuator in 1 dB steps. A flexible AGC port with digital input/output pins allows fast control of the AD6676 on-chip step attenuator and/or updates on the input signal via status flags. These features, along with the high instantaneous dynamic range, can significantly simplify AGC implementation compared to traditional narrow-band IF approaches that often require separate AGC capability for RF and IF protection. In addition to reducing system complexity, the AD6676 enables significant space and power consumption savings for next generation multiple input/multiple output (MIMO) receiver architectures. The AD6676 is available in an 8 × 10 ball array WLCSP package that is approximately 4.3 mm × 5.0 mm, with a JESD204B serial interface that allows simple interfacing to the host processor. Its low power consumption of 1.2 W compares favorably to IF sampling ADCs with similar bandwidth (BW) and dynamic range capabilities even without considering the added power savings from the elimination of an entire IF strip. The AD6676 features multichip synchronization that allows synchronization to within a fraction of an output data sample. For time-domain duplex (TDD) applications, the AD6676 features a fast power- up/power-down mode that further reduces power consumption while still maintaining multichip synchronization. Power savings of up to 60% or 42% is achievable with recovery times of 11.5 μs or 2.5 μs, depending on the device configuration. Auxiliary blocks include an on-chip PLL clock multiplier to generate the Σ-Δ ADC clock. For applications that require better phase noise performance, an external differential RF clock source may also be used. The SPI port programs numerous parameters of the AD6676, allowing the device to be optimized for a variety of applications. The AD6676 is available in an 80-ball WLCSP package with an optimized pinout that enables low cost printed circuit board (PCB) manufacturing. The device operates from a 1.1 V and 2.5 V supply with a total typical power consumption of 1.2 W at 3.2 GSPS operation. This product is protected by several United States patents.

Industry leading dynamic range enables high performance, reconfigurable heterodyne (or direct sampling VHF) software defined radios with high AGC-free range. 2. Continuous time, band-pass Σ-Δ ADC supports IFs from 70 MHz to 450 MHz with IF signal bandwidths of up to 160 MHz and reduces IF filtering requirements. 3. The high instantaneous dynamic range and oversampling nature of the Σ-Δ ADC significantly reduces the IF filter complexity. 4. On-chip 27 dB digital attenuator with easy to drive resistive input simplifies interface to RF/IF components. 5. Small 4.3 mm × 5.0 mm package, simple interface, and integrated digital attenuator and clock synthesizer save PCB space. 6. Low input full-scale level of −2 dBm (or less) enables 3.3 V RF/IF component lineups at reduced P1dB and power. 7. Fast power saving mode supports TDD protocols. 8. Unique profile mode allows the AD6676 to switch between up to four different ADC IF/BW configurations in 1 μs. |
