Wideband IF Receiver Chip Provides Industry Leading Dynamic Range in a Highly Integrated Solution
AD6676 "IF subsystem-on-a-chip" uses bandpass sigma delta A/D converter technology to digitize IF signals between 70 and 450 MHz with bandwidth up to 160 MHz.
The enabling technology behind the performance of the AD6676 is a highly programmable continuous-time bandpass sigma delta A/D converter (CTBPSD) topology which combines highly programmable analog filtering functionality with high dynamic range conversion. The implementation in deep sub-micron CMOS allows the advantages of oversampling by providing digitized bandwidth of up to 160Mhz. This provides a combination of features that enables "reconfigurable radio" architectures for high-performance heterodyne systems.
AD6676 IF Subsystem-on-a-Chip Key Features
-
Industry Leading Dynamic Range : can be configured to achieve a noise figure of 13 dB, IIP3=36dBM, noise spectral density (NSD) as low as -160 dBFS/Hz. - Flexibility: can be configured for IF frequencies from 70 MHz up to 450 MHz, IF bandwidths from 20 MHz up to 160 MHz and input full scales from -14dBm to +10dBm. A unique profile feature allows the AD6676 to switch between up to four different IF and bandwidth configurations within 1 microsecond.
- Integration: CTBPSD architecture removes the need for IF SAW filters and gain blocks, significantly simplifying the interface to an RF mixer. The input provides a programmable digital attenuator, allowing gain control functionality with an easy-to-drive resistive interface. The AD6676 also includes a fully integrated clock synthesizer, digital down converter, and JESD204B serial interface. The net result is a receiver solution offering up to 70 percent board space savings.
