Texas Instruments today introduced a new ultra-high-speed analog-to-digital converter (ADC) with the industry’s widest bandwidth, fastest sampling rate and lowest power consumption. The ADC12DJ5200RF helps engineers achieve high measurement accuracy for 5G testing applications and oscilloscopes, and direct X-band sampling for emerging technologies in radar, microwave, and mmWave.
“In general, what we are doing is pushing the envelope of what is out there,” says Phillip Pratt, TI’s Business Development and Technical Marketing Manager for High Speed Data Converters, “The 10 mm x 10 mm footprint of the device integrates an entire RF-to-bits receiver to drive out to the 9 – 10 GHz frequencies. Removing the RF stages, as well as integrating the DDC (digital down converter) means we can decrease the number of components needed to downconvert. Additionally, JESD204C standard interface support means fewer SERDES connections are needed to out data to FPGAs.”
At 8 GHz, the ADC12DJ5200RF enables engineers to achieve as much as 20 percent higher analog input bandwidth than competing devices, which gives engineers the ability to directly digitize very high frequencies without the power consumption, cost and size of additional down-conversion.
In dual-channel mode, the ADC12DJ5200RF samples at 5.2 gigasamples per second (GSPS) and captures instantaneous bandwidth (IBW) as high as 2.6 GHz at 12-bit resolution. In single-channel mode, the new ultra-high-speed ADC samples at 10.4 GSPS and captures IBW up to 5.2 GHz.
The ADC has the highest available dynamic performance across power-supply variations, even at minimum specifications, which improves signal intelligence by providing ultra-high receiver sensitivity to detect even the smallest and weakest signals. In addition, the device includes internal dither which improves spurious-free performance. System errors are minimized with offset error as low as ±300 µV and zero temperature drift.
Engineers designing test and measurement equipment can achieve high measurement repeatability by taking advantage of the extremely low code error rate (CER) of the ADC12DJ5200RF, which is more than 100 times better than competing devices. At 4-W power consumption, the device achieves 20 percent less power consumption than competitive ADCs
The ADC12DJ5200RF is pin-compatible with the following other TI GSPS ADCs to provide an easy upgrade path from 2.7 GSPS to 10.4 GSPS, and minimizes the time and cost of redesign: ADC12DJ3200, ADC12DJ2700 and ADC08DJ3200.
The ADC12DJ5200RF dual- and single-channel ultra-high-speed ADC is available for sampling through the TI store. The device is in a 144-ball, 10-by-10-mm flip-chip ball grid array (FCBGA) package.
