ADC32J2x Dual-Channel, 12-Bit, 50-MSPS to 160-MSPS, Analog-to-Digital Converter
with JESD204B Interface
1 Features
3 Description
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

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.
