Description
12-Bit, 170 MSPS/210 MSPS/250 MSPS, 1.8 V Analog-to-Digital Converter AD9230 FEATURES SNR = 64.9 dBFS @ fIN up to 70 MHz @ 250 MSPS ENOB of 10.4 @ fIN up to 70 MHz @ 250 MSPS (−1.0 dBFS) SFDR = −79 dBc @ fIN up to 70 MHz @ 250 MSPS (−1.0 dBFS) Excellent linearity DNL = ±0.3 LSB typical INL = ±0.5 LSB typical LVDS at 250 MSPS (ANSI-644 levels) 700 MHz full power analog bandwidth On-chip reference, no external decoupling required Integrated input buffer and track-and-hold Low power dissipation 434 mW @ 250 MSPS—LVDS SDR mode 400 mW @ 250 MSPS—LVDS DDR mode Programmable input voltage range 1.0 V to 1.5 V, 1.25 V nominal 1.8 V analog and digital supply operation Selectable output data format (offset binary, twos complement, Gray code) Clock duty cycle stabilizer Integrated data capture clock APPLICATIONS Wireless and wired broadband communications Cable reverse path Communications test equipment Radar and satellite subsystems Power amplifier linearization GENERAL DESCRIPTION The AD9230 is a 12-bit monolithic sampling analog-to-digital converter optimized for high performance, low power, and ease of use. The product operates at up to a 250 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. All necessary functions, including a track-and-hold (T/H) and voltage reference, are included on the chip to provide a complete signal conversion solution. The ADC requires a 1.8 V analog voltage supply and a differential clock f...
