The ADC32J2x is a high-linearity, ultra-low power, dual-channel, 12-bit, 50-MSPS to
160-MSPS, analog-to-digital converter (ADC) family. The 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 and the SYSREF input
enables complete system synchronization. The devices support JESD204B interfaces in order to reduce
the number of interface lines, thus allowing for high system integration density. The JESD204B
interface is a serial interface, where the data of each ADC are 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 12-bit data from each channel. The
devices support subclass 1 with interface speeds up to 3.2 Gbps.
