ADS5547
SLWS192A – NOVEMBER 2006 – REVISED MAY 2007
14-BIT, 210 MSPS ADC WITH DDR LVDS/CMOS OUTPUTS
• Maximum Sample Rate: 210 MSPS
ADS5547 is a high performance 14-bit, 210-MSPS
A/D converter. It offers state-of-the art functionality
• 14-Bit Resolution
and performance using advanced techniques to
• No Missing Codes
minimize board space. With high analog bandwidth
• Total Power Dissipation 1.23 W
and low jitter input clock buffer, the ADC supports
• Internal Sample and Hold both high SNR and high SFDR at high input
frequencies. It features programmable gain options
• 73.3-dBFS SNR at 70-MHz IF
that can be used to improve SFDR performance at
• 85-dBc SFDR at 70-MHz IF, 0-dB gain
lower full-scale analog input ranges.
• High Analog Bandwidth up to 800 MHz
In a compact 48-pin QFN, the device offers fully
• Double Data Rate (DDR) LVDS and Parallel
differential LVDS DDR (Double Data Rate) interface
CMOS Output Options
while parallel CMOS outputs can also be selected.
Flexible output clock position programmability is
• Programmable Gain up to 6 dB for SNR/SFDR
available to ease capture and trade-off setup for hold
