The AD9683 is a 14-bit ADC with sampling speeds of up to 250 MSPS. The AD9683 supports communications applications where low cost, small size, wide bandwidth, and versatility are desired. The ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. The ADC core features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer (DCS) is provided to compensate for variations in the ADC clock duty cycle, allowing the converter to maintain excellent performance. The JESD204B high speed serial interface reduces board routing requirements and lowers pin count requirements for the receiving device. The ADC output data is routed directly to the JESD204B serial output lane. These outputs are at CML voltage levels. Data can be sent through the lane at the maximum sampling rate of 250 MSPS, which results in a lane rate of 5 Gbps. Synchronization inputs (SYNCINB± and SYSREF±) are provided. Flexible power-down options allow significant power savings, when desired. Programmable overrange level detection is supported via the dedicated fast detect pins. Programming for setup and control is accomplished using a 3-wire SPI-compatible serial interface. The AD9683 is available in a 32-lead LFCSP and is specified over the industrial temperature range of −40°C to +85°C.
Product Highlights
- Integrated 14-bit, 170 MSPS/250 MSPS ADC.
- The configurable JESD204B output block supports lane rates up to 5 Gbps.
- An on-chip, phase-locked loop (PLL) allows users to provide a single ADC sampling clock; the PLL multiplies the ADC sampling clock to produce the corresponding JESD204B data rate clock.
- Support for an optional radio frequency (RF) clock input to ease system board design.
- Proprietary differential input maintains excellent SNR performance for input frequencies of up to 400 MHz.
- Operation from a single 1.8 V power supply.
- Standard serial port interface (SPI) that supports various product features and functions, such as controlling the clock DCS, power-down, test modes, voltage reference mode, overrange fast detection, and serial output configuration.

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.

Tools & Simulations
AD9683 Simulink ADIsimADC Model
Open ToolADIsimRF
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
Open ToolADC 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.
