The AD9234 is a dual, 12-bit, 1 GSPS/500 MSPS ADC. The device has an on-chip buffer and sample-and-hold circuit designed for low power, small size, and ease of use. This product is designed for sampling wide bandwidth analog signals. The AD9234 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.
The dual ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth buffered inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. Each ADC data output is internally connected to an optional decimate-by-2 block. The AD9234 has several functions that simplify the automatic gain control (AGC) function in a communications receiver.
The programmable threshold detector allows monitoring of the incoming signal power using the fast detect output bits of the ADC. If the input signal level exceeds the programmable threshold, the fast detect indicator goes high. Because this threshold indicator has low latency, the user can quickly turn down the system gain to avoid an overrange condition at the ADC input. In addition to the fast detect outputs, the AD9234 also offers signal monitoring capability. The signal monitoring block provides additional information about the signal being digitized by the ADC.
Users can configure the Subclass 1 JESD204B-based high speed serialized output in a variety of one-, two-, or four-lane configurations, depending on the acceptable lane rate of the receiving logic device and the sampling rate of the ADC. Multiple device synchronization is supported through the SYSREF± and SYNCINB± input pins.
The AD9234 has flexible power-down options that allow significant power savings when desired. All of these features can be programmed using a 1.8 V to 3.3 V capable 3-wire SPI.
The AD9234 is available in a Pb-free, 64-lead LFCSP and is specified over the −40°C to +85°C industrial temperature range. This product is protected by a U.S. patent.

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.

ADC Companion Transport Layer RTL Code Generator Tool
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.
