16-Bit, 250 MSPS ADC Sets Performance Standards

Mon, 09/27/2010 - 9:03am
ADI today announced the industry’s fastest 16-bit ADC (analog-to-digital converter) - at 250 MSPS (mega samples per second.) The AD9467 16-bit, 250 MSPS ADC provides a new level of signal processing performance for communications, test and measurement and defense electronics applications. The AD9467 features a high SFDR (spurious-free dynamic range) of up to 100 dBFs (90 dBFs up to 300 MHz) and SNR (signal-to-noise ratio) performance of 76.4 dBFS.

The converter is effective for, radar systems, spectrum analyzers and multi-carrier, multi-mode receiver designs for wireless infrastructure equipment that are defined by high resolution and throughput. The device’s SFDR performance and 60-femtosecond rms (root mean square) jitter allow engineers to increase system performance even as they reduce the size of their equipment.

Key features and benefits of the AD9467 include: * 16-bit resolution with high signal bandwidths up to 300 MHz enables advanced signal acquisition subsystems in common radio platforms, radar systems and spectrum analysis.

* On-chip IF (intermediate frequency) sampling circuit and buffered analog inputs optimize the AD9467 for the highest ENOB (effective number of bits) and ease of use.

* High dynamic range over broad signal bandwidth enables software-defined radios for use with multiple standards, such as LTE/W-CDMA, MC-GSM (class 1) and CDMA.

* Programmable full-scale input range allows trade-off between SNR and SFDR enabling the design of more sensitive radar systems with the ability to acquire and track smaller targets with better accuracy.

As part of a complete signal chain, the AD9467 can be used with the AD9523/24 low-jitter clock generators and the ADL5562 3.3 GHz ultralow distortion RF/IF differential amplifier to provide a data conversion signal chain solution.
