ADC14V155 14-Bit, 155 MSPS, 1.1 GHz Bandwidth A/D Converter with LVDS Outputs April 2007 ADC14V155 14-Bit, 155 MSPS, 1.1 GHz Bandwidth A/D Converter with LVDS Outputs General Description Features The ADC14V155 is a high-performance CMOS analog-to■ 1.1 GHz Full Power Bandwidth digital converter with LVDS outputs. It is capable of converting ■ Internal sample-and-hold circuit analog input signals into 14-Bit digital words at rates up to 155 ■ Low power consumption Mega Samples Per Second (MSPS). Data leaves the chip in ■ Internal precision 1.0V reference a DDR (Dual Data rate) format; this allows both edges of the ■ Single-ended or Differential clock modes output clock to be utilized while achieving a smaller package size. This converter uses a differential, pipelined architecture ■ Clock Duty Cycle Stabilizer with digital error correction and an on-chip sample-and-hold ■ Dual +3.3V and +1.8V supply operation (+/- 10%) circuit to minimize power consumption and the external com■ Power-down and Sleep modes ponent count, while providing excellent dynamic perfor■ Offset binary or 2's complement output data format mance. A unique sample-and-hold stage yields a full-power bandwidth of 1.1 GHz. The ADC14V155 operates from dual ■ LVDS outputs +3.3V and +1.8V power supplies and consumes 951 mW of ■ 48-pin LLP package, (7x7x0.8mm, 0.5mm pin-pitch) power at 155 MSPS.
