ADC34J2x Quad-Channel, 12-Bit, 50-MSPS to 160-MSPS, Analog-to-Digital Converter  
with JESD204B Interface  
1 Features  
3 Description  
The ADC34J2x are 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 while  
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.
