Texas Instruments ADC3444
The ADC344x devices are a high-linearity, ultra-low power, quad-channel, 14-bit, 25-MSPS to 125-MSPS, analog-to-digital converter (ADC) family. The devices are designed specifically to support demanding, high input frequency signals with large dynamic range requirements. The ADC344x family supports serial low-voltage differential signaling (LVDS) to reduce the number of interface lines, thus allowing for high system integration density.| Part No. | ADC3444 |

DESCRIPTION
An input clock divider allows more flexibility for system clock architecture design while the SYSREF input enables complete system synchronization. The serial LVDS interface is twowire, where each ADC data are serialized and output over two LVDS pairs.
