The AD9699 is a single, 14-bit, 3 GSPS analog-to-digital converter (ADC). The device has an on-chip buffer and a sample-and-hold circuit designed for low power, small size, and ease of use. This product is designed to support applications capable of direct sampling wide bandwidth analog signals of up to 5 GHz. The −3 dB bandwidth of the ADC input is 9 GHz. The AD9699 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.
The ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. The 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. The ADC data outputs are internally connected to four digital down-converters (DDCs) through a crossbar multiplexer (mux). Each DDC consists of up to five cascaded signal processing stages: a 48-bit frequency translator (numerically controlled oscillator (NCO)), and up to four half-band decimation filters. The NCO has the option to select preset bands over the general-purpose input/output (GPIO) pins, which enables the selection of up to three bands. Operation of the AD9699 between the DDC modes is selectable via serial peripheral interface (SPI)-programmable profiles.
In addition to the DDC blocks, the AD9699 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 control bits in Register 0x0245 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 AD9699 also offers signal monitoring capability. The signal monitoring block provides additional information about the signal being digitized by the ADC.
The user can configure the Subclass 1 JESD204B-based high speed serialized output in a variety of one-lane, two-lane, four-lane, and eight-lane configurations, depending on the DDC configuration and the acceptable lane rate of the receiving logic device. Multi-device synchronization is supported through the SYSREF± and SYNCINB± input pins.
The AD9699 has flexible power-down options that allow significant power savings when desired. All of these features can be program-med using a 3-wire SPI.
The AD9699 is available in a Pb-free, 12 mm × 12 mm, 196-ball BGA and is specified over the −40°C to +85°C ambient temperature range. This product is protected by a U.S. patent.
Note that throughout the data sheet, multifunction pins, such as FD/GPIO_A0, are referred to either by the entire pin name or by a single function of the pin, for example, FD, when only that function is relevant.

Tools & Simulations
Simulate performance of ADCs and DACs under your operating conditions.
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.
