Product Details

The AD9083 is a 16-channel, 125 MHz bandwidth, continuous time Σ-Δ (CTSD) ADC. The device features an on-chip, programmable, single-pole antialiasing filter and termination resistor that is designed for low power, small size, and ease of use.

The 16 ADC cores features a first-order, CTSD modulator architecture with integrated, background nonlinearity correction logic and self cancelling dither. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations.

The analog input and clock signals are differential inputs. Each ADC has a signal processing tile to filter out of band shaped noise from the Σ-Δ ADC and reduce the sample rate. Each tile contains a cascaded integrator comb (CIC) filter, a quadrature digital downconverter (DDC) with multiple finite input response (FIR) decimation filters (decimate by J block), or up to three quadrature DDC channels with averaging decimation filters for data gating applications.

Users can configure the Subclass 1 JESD204B based, high speed serialized output in a variety of lane configurations (up to four), depending on the DDC configuration and the acceptable lane rate of the receiving logic device. Multiple device synchronization is supported through the SYSREF±, TRIG±, and SYNCINB± input pins.

The AD9083 has flexible power-down options that allow significant power savings when desired. All of these features can be programmed using a 1.8 V capable 3-wire serial port interface (SPI).

The AD9083 is available in a Pb-free, 100-ball CSP_BGA and is specified over the −40°C to +85°C industrial temperature range.

This product is protected by a US patent.

Software & Systems Requirements

Device Drivers

API Device Drivers

Device Application Programming Interface (API) C code drivers provided as reference code that allows the user to quickly configure the product using high-level function calls. The library acts as an abstraction layer between the application and the hardware. The API is developed in C99 to ensure agnostic processor and operating system integration. Customers can port this application layer code to their embedded systems by integrating their platform-specific code base to the API HAL layer.

To request this software package, go to the Software Request Form signed in with your MyAnalog account and under “Target Hardware” select “High Speed Data Converters” and choose the desired API product package. You will receive an email notification once the software is provided to you.

Tools & Simulations

Design Tools

Companion Transport Layer RTL Code Generator Tool (Rev. 1.0)

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.

JESD204x Frame Mapping Table Generator

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.
