ADC offers wide bandwidth and low phase noise for next-generation high-speed systems

Texas Instruments has introduced an ADC and PLL with an integrated VCO that is claimed to deliver the widest bandwidth, lowest phase noise and highest dynamic range in the industry. The wideband ADC12DJ3200 is the fastest 12-bit ADC, delivering speeds up to 6.4GSPS. The LMX2594 is claimed to be the industry's first wideband PLL solution to generate frequencies of up to 15GHz without using an internal frequency doubler. High-density phased-array radar systems, 5G systems and satellite communications demand increased data throughput, higher bandwidth and lower power, all in smaller a footprint. A multi-node synchronization reference design demonstrates how the devices provide accurate, time-stable synchronization for multi-node sampling systems including large-scale phased-array radars, DSOs and 5G wireless testers. The reference design showcases the LMX2594's SYSREF forwarding feature and the ADC12DJ3200's aperture delay adjust, time stamp and calibration features to improve accuracy and ease system design.
