The ADC12J4000 combines TI's existing giga-sample ADC intellectual property (IP) with low-power digital processing blocks that provide digital filtering and down conversion. This enables system designers to sample a large block of frequency spectrum at RF and down convert it to quadrature in the digital domain, which can reduce signal distortion. And because the ADC12J4000 utilizes the JESD204B serial interface standard, it can output data on 1 to 8 lanes, depending on the decimation and link rate settings, while simplifying layout.

An evaluation module (EVM) is available to quickly evaluate the performance of the new ADC. System designers can pair the ADC12J4000EVM, which includes the LMK04828 JESD204B clock jitter cleaner and LMX2581 ultra-low noise, wideband frequency synthesizer with the TSW14J56EVM JESD204B solutions platform to fully evaluate the performance of the ADC12J4000. When used together, the ADC12J4000EVM and TSW14J56EVM can analyze complex and modulated signals, which can then be analyzed with TI's easy-to-use High Speed Data Converter Pro software.

The ADC12J4000 is available now in a 68-pin, 10-mm by 10-mm QFN package that supports the industrial ambient temperature range of -40C to +85C.

Samples of the pin-compatible 2,700-MSPS ADC12J2700 and 1,600-MSPS ADC12J1600 are expected in 1Q 2014 with production quantities expected in 3Q 2014.

Feartures:

• Wideband sampling: Provides RF sampling capabilities with more than 3-GHz input bandwidth.

• Lowest power consumption: Consumes only 1.9 W of power, 50 percent less than competitive devices.

• Unique multi-band summation: Can perform some of the external signal conditioning typically handled by the FPGA at a total decimation at 4/8/10/16/20/32x. This provides attenuation of approximately 80-dB at 80 percent bandwidth, 44 dB at 85 percent and 24 dB at 90 percent, enabling system designers to filter higher frequency signals to lower data rates for their applications.

• Flexible signal bandwidth: Provides a low-noise power ratio of 48.5 dB and noise floor of -149 dBFS/Hz, along with high linearity for signals up to and beyond intermediate frequencies of 3 GHz. These features enable system designs to sample at higher frequencies.

• RF-sampling analog front-end: The pin-compatible, 4-GSPS, ultra-wideband, RF-sampling LM15851 analog front end (AFE) is export license free.
