Texas Instruments ADC3222
The ADC322x are a high-linearity, ultra-low power, dual-channel, 12-bit, 25-MSPS to 125-MSPS, analogto-digital converter (ADC) family. The devices are designed specifically to support demanding, high input frequency signals with large dynamic range requirements. The ADC322x family supports serial low-voltage differential signaling (LVDS) in order to reduce the number of interface lines, thus allowing for high system integration density.| Part No. | ADC3222 |

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