ADS6125IRHBTG4 (TEXAS INSTRUMENTS)

The ADS6125IRHBTG4 is a 12-bit Analog-to-digital Converter (ADC) with sampling frequencies up to 125MSPS. Using an internal high bandwidth sample and hold and a low jitter clock buffer helps to achieve high SNR and high SFDR even at high input frequencies. It features coarse and fine gain options that are used to improve SFDR performance at lower full-scale analog input ranges. The digital data outputs are either parallel CMOS or DDR LVDS. Several features exist to ease data capture such as - controls for output clock position and output buffer drive strength and LVDS current and internal termination programmability. The output interface type, gain and other functions are programmed using a 3-wire serial interface. Alternatively, some of these functions are configured using dedicated parallel pins so that the device comes up in the desired state after power-up. The ADC includes internal references, while eliminating the traditional reference pins and associated external decoupling.
