TI Delivers Widest Bandwidth and Lowest Phase Noise for Next-Generation High-Speed Systems

Texas Instruments has announced the availability of an analog-to-digital converter (ADC) and phased-locked loop (PLL) with an integrated voltage-controlled oscillator (VCO). These new offerings will deliver the widest bandwidth, lowest phase noise, and highest dynamic range in the industry. ADC12DJ3200 is the fastest 12-bit ADC wideband with a speed of up to 6.4 GSPS while the LMX2594 is the industry’s first wideband PLL solution that generates frequencies of up to 15 GHz without any 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 a smaller footprint. A multi-node synchronization reference design demonstrates how the ADC12DJ3200 and LMX2594 render accurate, time-stable synchronization for multi-node sampling systems. These systems include large-scale phased-array radars, digital storage oscilloscopes (DSOs) and 5G wireless testers. The reference design showcases the LMX2594’s SYSREF forwarding feature along with the ADC12DJ13200’s aperture delay adjust, time stamp and calibration features to improve accuracy and ease system design.

 

 

 

• It features the industry’s lowest normalized PLL noise floor of -236 dCc/Hz and 1/f of -129 dBc/Hz. This helps designers to improve radiosensitivity and spectral resolution.

• The integrated VCO operates at up to 15 GHz and eliminates the need for expensive, complex on-board filters to remove subharmonics.

• It allows system designers to synchronize the output of all on-board PLLs so as to save design time for implementing multiple-input/multiple-output (MIMO).

• It simultaneously generates gigahertz frequency sampling and JESD204B SYSREF timing signals.

 

 

• Features the industry’s fastest sample rate of 6.4 GSPS at a 12-bit resolution and allows the designers to capture the widest bandwidth possible.

• It enables simplifies system architectures and provides enhanced frequency agility with a reduction in filter complexity and saving the board space as well as component count.

• The 10-mm-by-10-mm device integrates an entire RF-to-bits receiver, reducing board space by up to 88%.

• It consumes as little as 3W along with twice the input frequency range at half the power of competing devices.

 

 

The ADC is available in a flip-chip ball-grid array (FCBGA) package at USD 1,920 in 100-unit quantities. The LMX2594 is fully orderable and comes in a very thin quad flat no-lead package at USD 41 in 1,000-unit quantities.
