4-channel, 14-bit, 105MSPS Analog-to-Digital Converter
4通道,14位,105MSPS 模數轉換器IC ADS6444IRGCT

4通道,14位,105MSPS 模數轉換器IC ADS6444IRGCT的說明
The ADS6445/ADS6444/ADS6443/ADS6442 (ADS644X) is a family of high performance 14-bit 125/105/80/65 MSPS quad channel A-D converters. Serial LVDS data outputs reduce the number of interface lines, resulting in a compact 64-pin QFN package (9 mm × 9 mm) that allows for high system integration density. The device includes 3.5dB coarse gain option that can be used to improve SFDR performance with little degradation in SNR. In addition to the coarse gain, fine gain options also exist, programmable in 1dB steps up to 6dB.

The output interface is 2-wire, where each ADC data is serialized and output over two LVDS pairs. This makes it possible to halve the serial data rate (compared to a 1-wire interface) and restrict it to less than 1Gbps easing receiver design.
