For a limited time, take a live test drive of the AD6676 by using our remote evaluation software.

The AD6676 is a highly integrated IF subsystem that candigitize radio frequency (RF) bands up to 160 MHz in widthcentered on an intermediate frequency (IF) of 70 MHz to 450 MHz. Unlike traditional Nyquist IF sampling ADCs, theAD6676 relies on a tunable band-pass Σ-Δ ADC with a high oversampling ratio to eliminate the need for band specific IFSAW filters and gain stages, resulting in significant simplification of the wideband radio receiver architecture. On-chip quadraturedigital downconversion followed by selectable decimation filtersreduces the complex data rate to a manageable rate between 62.5 MSPS to 266.7 MSPS. The 16-bit complex output data is transferred to the host via a single or dual lane JESD204B interfacesupporting line rates of up to 5.333 Gbps.
