ADS58H43 www.ti.com SBAS598 – NOVEMBER 2012 Quad-Channel, 250-MSPS Receiver and Feedback ADC Check for Samples: ADS58H43 FEATURES 1 2 Quad Channel Three Different Operating Modes: – 11-Bit: 250 MSPS – 11-Bit SNRBoost3G+: 250 MSPS – 14-Bit: 250 MSPS (Burst Mode) Maximum Sampling Data Rate: 250 MSPS Power Dissipation: – 11-Bit Mode: 365 mW per Channel SNRBoost3G+ Bandwidth: 2x 45 MHz or 90 MHz Spectral Performance at 170 MHz IF (typ): – SNR: 70.5 dBFS in 90-MHz Band with SNRBoost3G+ – SFDR: 85 dBc DDR LVDS Digital Output Interface 144-Pad BGA (10-mm × 10-mm) DESCRIPTION The ADS58H43 is a high-linearity, quad-channel, 14bit, 250-MSPS analog-to-digital converter (ADC). The four ADC channels are separated into two blocks with two ADCs each. Each block can be individually configured into three different operating modes. One operating mode includes the implementation of the SNRBoost3G+ signal processing technology to provide high signal-to-noise ratio (SNR) in a band up to 90 MHz wide with only 11-bit resolution. Designed for low power consumption and high spurious-free dynamic range (SFDR), the ADC has low-noise performance and outstanding SFDR over a large input frequency range.
