Datasheet

Texas Instruments introduced the lowest power 11-bit, 200 MSPS ADC family, with quad (ADS58C48), dual (ADS58C28) and buffered single-input (ADS58B18) options. Featuring SNRBoost technology, the ADCs deliver enhanced in-band signal-to-noise ratio (SNR) for multi-carrier and multi-mode communications systems requiring up to 65 MHz of signal bandwidth, such as CDMA, WCDMA, TD-SCDMA, LTE and WiMAX.

For instance, the SNRBoost technology in the ADS58C48 provides up to 4.3 dB greater SNR at 185 MSPS across 60 MHz of bandwidth, delivering increased bandwidth and sensitivity for a wide array of communications applications including remote radio heads, software defined radios, wireless repeaters and MIMO and diversity receivers.

Key features and benefits

* Programmable SNRBoost technology delivers up to 72.3 dB SNR across 60 MHz bandwidth or 75.4 db SNR across 30 MHz bandwidth, allowing customers to achieve 3G and 4G receiver sensitivity specifications.
* Industry-leading power consumption: 215 mW/channel (ADS58C48), 230 mW/channel (ADS58C28), 310 mW/channel (ADS58B18) at 200 MSPS. Enables manufacturers to design low-power, high-density, two- and four-channel receivers and digital pre-distortion (DPD) feedback loops.
* Input options and user-selectable CMOS or DDR LVDS allows for easy connection to TI GCxxxx digital radio products, FPGA and digital ASIC solutions.
* Evaluation modules and TSW1200 digital capture tool facilitate rapid evaluation and prototyping.
* Compete signal chain including the DAC3283, PGA870, TRF3704, CDCE72010, GC5325, TMS320C6727 speeds time to market.
