Wide Bandwidth, Low Phase Noise for High-Speed Systems: TI Releases ADC12DJ3200 ADC and LMX2594 PLL
In this news brief, we look at the ADC12DJ3200 and the LMX2594 from Texas Instruments. Both products work together to help widen bandwidth and lower phase noise for high-speed systems.

Texas Instruments recently released two new products: the ADC12DJ3200 and the LMX2594. The two products are additions to TI's portfolio of RF sampling data converters and wideband clock timing devices. Using the products together assists designers with completing a JESD204B-compliant design. High-density phased-array radar systems, 5G systems, and satellite communications are just a few areas these products will benefit.

The ADC12DJ3200 is a 12-bit analog-to-digital converter that delivers speeds up to 6.4 GSPS with 12-bit resolution, which allows designers to capture the widest bandwidth possible to generate information. The device measures 10x10 mm and includes an RF-to-bits receiver to save board space. It consumes as little as 3 W of power. Direct RF-sampling of up to 10 GHz covers the L-band, S-band, C-band, and extends to the X-band.

- Time-of-flight and LIDAR distance measurement
- Oscilloscopes and wideband digitizers
- RF sampling software defined radio (SDR)
The LMX2594 PF PLL with VCO is the industry’s first wideband phase-locked loop to produce frequencies up to 15 GHz without the help of an internal frequency doubler. Because it already contains an integrated VCO, the LMX2594 automatically generates a frequency ramp. It has the industry’s lowest normalized PLL noise floor (-236 dBc/Hz and 1/f of -129 dBc/Hz) to help improve radiosensitivity and spectral resolution. Designers can synchronize the output of all onboard PLLs to assist in implementing MIMO in their applications.
