Product Details

The AD9209 is a quad, 12-bit, 4 GSPS analog-to-digital converter (ADC). The ADC input features an on-chip wideband buffer with overload protection. This device is designed to support applications capable of direct sampling wideband signals up to 8 GHz. An on-chip, low phase noise, phase-locked loop (PLL) clock synthesizer is available to generate the ADC sampling clock, simplifying the printed circuit board (PCB) distribution of a high frequency clock signal. A clock output buffer is available to transmit the ADC sampling clock to other devices.

The quad ADC cores have code error rates (CER) better than 1 × 10−20. Low latency fast detection and signal monitoring are available for automatic gain control (AGC) purposes. A flexible 192-tap programmable finite impulse response filter (PFIR) is avail-able for digital filtering and/or equalization. Programmable integer and fractional delay blocks support compensation for analog delay mismatches.

The digital signal processing (DSP) block consisting of two coarse digital down converters (DDCs) and four fine DDCs per pair of ADCs. Each ADC can operate with one or two main DDC stages in support of multiband applications. The four additional fine DDC stages are available to support up to four bands per ADC The 48-bit numerically controlled oscillators (NCOs) associated with each DDC support fast frequency hopping (FFH) while maintaining synchronization with up to 16 unique frequency assignments selected via the general-purpose input and output (GPIOx) pins or the serial port interface (SPI).

The AD9209 supports one or two JTx links that can be configured for either JESD204B or JESD204C subclass operation, thus allowing for different datapath configurations for each ADC. Multidevice synchronization is supported through the SYSREF± input pins.

Tools & Simulations

Design Tools

MxFE JESD204 Mode Selector Tool

The JESD204B/C Mode Selector Tool is a simple command line-based Windows executable that can be used to narrow down the number of JESD204x modes to only include those modes that support the user’s specific application use case. The tool guides the user through a use case description flow chart and gives the user a small list of applicable transmit and/or receive modes to choose from. This tool is applicable to the AD9081, AD9082, AD9177, AD9207, AD9209, AD9986, and AD9988.

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.
