ADC3x High-Speed 12/14-Bit ADCs

Texas Instrument ADC3x High-Speed 12/14-Bit Analog-to-Digital Converters are a high-linearity, ultra-low power, dual-channel, 12 or 14-bit, 25-MSPS to 125-MSPS, analog-to-digital converters (ADCs). These devices are designed specifically to support demanding, high input frequency signals with large dynamic range requirements. An input clock divider allows more flexibility for system clock architecture design and the SYSREF input enables complete system synchronization. The ADC3x supports serial low-voltage differential signaling (LVDS) in order to reduce the number of interface lines, thus allowing for high system integration density. The serial LVDS interface is two-wire, where each ADC data are serialized and output over two LVDS pairs. An internal phase-locked loop (PLL) multiplies the incoming ADC sampling clock to derive the bit clock that is used to serialize the 12 or 14-bit output data from each channel.
