    TI unveils High-speed systems with widest Bandwidth and lowest Phase Noise

    Texas Instruments (TI) on 31 May, introduced an analog-to-digital converter (ADC) and phase-locked loop (PLL) with an integrated voltage-controlled oscillator (VCO) that 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 6.4 GSPS. The LMX2594 is the industry’s first wideband PLL solution to generate frequencies of up to 15 GHz 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 ADC12DJ3200 and LMX2594 provide accurate, time-stable synchronization for multi-node sampling systems including large-scale phased-array radars, digital storage oscilloscopes (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.

    Next-generation architectures can take advantage of the ADC12DJ3200 ADC with the following features and benefits:

    • Widest signal bandwidth: Featuring the industry’s fastest sample rate of 6.4 GSPS at a 12-bit resolution –18 percent faster than competitive devices – the ADC12DJ3200 enables designers to capture the widest bandwidth possible to process more information instantaneously.
    • Highest analog input-frequency range: With direct radio-frequency (RF) sampling up to 10 GHz covering the L-band, S-band and C-band and extending into the X-band, the ADC12DJ3200 enables simplified system architectures and provides enhanced frequency agility, while reducing filter complexity, in turn save board space and component count.
    • Saves space: The 10-mm-by-10-mm device integrates an entire RF-to-bits receiver, reducing board space by up to 88 percent compared to competing solutions while enabling designers to reduce cost by simplifying the system architecture.
    • Low power: Consuming as little as 3 W, the ADC provides twice the input frequency range at half the power of competing devices.
