ADC14V155 14-Bit Bandwidth A/D Converter

The ADC14V155 is a high-performance CMOS analog-todigital converter with LVDS outputs. It is capable of converting analog input signals into 14-Bit digital words at rates up to 155 Mega Samples Per Second (MSPS). Data leaves the chip in a DDR (Dual Data rate) format; this allows both edges of the output clock to be utilized while achieving a smaller package .
