Product Details
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 can digitize radio frequency (RF) bands up to 160 MHz in width centered on an intermediate frequency (IF) of 70 MHz to 450 MHz. Unlike traditional Nyquist IF sampling ADCs, the AD6676 relies on a tunable band-pass Σ-Δ ADC with a high oversampling ratio to eliminate the need for band specific IF SAW filters and gain stages, resulting in significant simplification of the wideband radio receiver architecture. On-chip quadrature digital downconversion followed by selectable decimation filters reduces 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 interface supporting line rates of up to 5.333 Gbps.
Applications

Design Tools
This command line executable tool generates a Verilog module which implements the JESD204 receive transport layer. The user specifies in a configuration file one or more modes to be supported by the transport layer module. These modes are defined as a set of JESD204 parameter values: L, M, F, S, N', and CF. The transport layer converts JESD204 lane data output from a JESD204 link layer IP to a data bus with a fixed width, containing interleaved virtual converter samples. Both JESD204B and JESD204C link layers are supported.
The JESD204x Frame Mapping Table Generator tool consists of two Windows executables that will allow the user to input any valid combination of JESD204x parameters (L, M, F, S, NP) in order to output a .csv file that illustrates the frame mapping of the JESD204x mode in table format. There is an executable that allows the user to input a single JESD204x mode and another, that allows the user to input the parameters for multiple JESD204x modes in a specified .csv format in order to output a .csv file that illustrates the frame mapping of each of the JESD204x modes that were input into separate tables.
