Telecom infrastructure, imaging equipment, industrial instrumentation, defense electronics, and other multi-channel, system required system require data conversion level to provide increasingly wider resolution and increasingly high sampling rates. The physical layout limit of the parallel interface and the bit rate limit of the serial LVDS (low pressure differential signal) method currently brings technical barriers to the designers. To solve this need, Analog Devices, Inc. (ADI: Nasdaq), the world's leading high-performance signal processing solution supplier and data conversion technology leader, recently introduced dual channel 14 with JEDEC JESD204B serial output data interface standard Bit 250 MSPS Mode Converter AD9250. The AD9250 ADC is a 250 MSPS ADC, which is fully reached in the market. The 250 MSPS ADC that requires a deterministic delay request, which supports multiple data conversion channels precision synchronization through a serial interface.
The serial interface scheme of the AD9250 ADC provides a sample rate of up to 5 Gbps through a single channel or dual channel link. Using two serial channels support 250 MSPS full-speed dual-channel modulus translation data rate, single channels are used to support lower sampling rates.
Xilinx Inc. Contains high-performance FPGA vendors, which have integrated JESD204B SerDes (Serializer / Stroke) ports in their latest generation. This end-to-end seamless connection scheme for analog signal chains simplifies the PCB layout, speeding up prototyping, making the product faster.
SUNIL KAR, senior director of the Xilinx Wireless Business Department, said: "Xilinx fully supports JEDEC JESD204B standards, and is working hard to speed up serializing technology using data converters. Currently, it is to provide high quality, flexible, scalable, programmable IP comes with high-speed data converter interfaces such as AD9250. The JEDEC JESD204B IP currently provided by XILINX supports Subclass 0, 1, 2 function, and the line rate can be up to 10.3 Gbps. The channel width range is 1 to 8 times. These technological progress is conducive to Promote system modular, reduce costs, complexity, enhance the function and capacity of new generation wireless and wired networks. "
KEVIN KATTMANN, Director of Adi High Speed Modulus Converter, said: "This flagship product of Adi provides a new high integrated method for analog signal chain gauges in the FPGA system. Double channel 14 ADC AD9250 has unparalleled Broadband signal processing performance, its simplified interface to clear design barriers for software-defined radio and medical ultrasound applications. For many system designers, the I / O facing the high-performance analog signal chain Challenge now has a fine solution. "

The JESD204B serial interface of the AD9250 converter reduces the number of high-speed differential output data paths required for each IC to 2. Each power-up period and after the link resynchronization event, its SubClass 1 determines the deterministic delay functionality. This function is important in the following applications: Diversity Radio Systems and Instruments, TD-SCDMA / WCDMA / LTE (especially 2R2T >8R8T Evolution) Multi-mode digital receiver applications, radar / defense electronic, medical imaging systems, cable Infrastructure and universal software radio.

Evaluation kit
AD9250-250EBZ (250 MSPS), AD9250-170EBZ (170 MSPS) and AD6673-250EBZ DUT board, with auxiliary high-speed data acquisition card HSC-ADC-Evaldz, constitutes a complete evaluation system for AD9250, which optimizes signal performance. The collected data can be analyzed using laptops and ADI free software VisualanalogTM. In order to be compatible with the FPGA development platform, the DUT board can use the CVT-ADC-FMC-INTPZB FMC interpolator connector.
Supply, quotation and supporting products
Dual-channel 14-bit 250 MSPS ADC AD9250 is suitable for working with other devices of ADI, including drive AD8138, ADA4937, and ADA4938-2, clock assignment IC AD9516-3, and low jitter clock buffer ADCLK905.
At the same time, 170 MSPS pin compatible versions (AD9250-170) and 11-bit 250 MSPS pin are also compatible with the AD6673.
