Texas Instruments ADC34J4x 14-Bit Analog-to-Digital Converters
Texas Instruments ADC34J4x 14-Bit Analog-to-Digital Converter (ADC) is a high-linearity, ultra-low power, quad-channel, 14-bit, 50MSPS to 160MSPS, analog-to-digital converter (ADC). These devices are designed specifically to support demanding, high input frequency signals with large dynamic range requirements. A clock input divider allows more flexibility for system clock architecture design while the SYSREF input enables complete system synchronization.
The Texas Instruments ADC34J4x family supports serial current-mode logic (CML) and JESD204B interfaces in order to reduce the number of interface lines, thus allowing high system integration density. The JESD204B interface is a serial interface, where the data of each ADC is serialized and output over only one differential pair. An internal phase-locked loop (PLL) multiplies the incoming ADC sampling clock by 20 to derive the bit clock that is used to serialize the 14-bit data from each channel. The ADC34J4x devices support subclass 1 with interface speeds up to 3.2Gbps.
