It offers state-of-the art functionality CMOS Output Options and performance using advanced techniques to minimize board space. Using an internal sample and • Programmable Gain up to 6 dB for SNR/SFDR hold and low jitter clock buffer, the ADC supports Trade-Off at High IF both high SNR and high SFDR at high input • Reduced Power Modes at Lower Sample frequencies. It features programmable gain options Rates that can be used to improve SFDR performance at • Supports input clock amplitude down to 400 lower full-scale analog input ranges. mVPP In a compact 48-pin QFN, the device offers fully • Clock Duty Cycle Stabilizer differential LVDS DDR (Double Data Rate) interface while parallel CMOS outputs can also be selected. • No External Reference Decoupling Required Flexible output clock position programmability is • Internal and External Reference Support available to ease capture and trade-off setup for hold • Programmable Output Clock position to ease times. At lower sampling rates, the ADC can be data capture operated at scaled down power with no loss in performance. ADS5546 includes an internal • 3.3-V Analog and Digital Supply reference, while eliminating the traditional reference • 48-QFN Package (7 mm × 7 mm) pins and associated external decoupling. The device also supports an external reference mode. The device is specified over the industrial • Wireless Communications Infrastructure temperature range (-40 °C to 85°C). • Software Defined Radio Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
