ADC322x

Dual-Channel, 12-Bit, 25-MSPS to 125-MSPS, Analog-to-Digital Converters

1 Features

3 Description

The ADC322x are a high-linearity, ultra-low power,

dual-channel, 12-bit, 25-MSPS to 125-MSPS, analog-

to-digital converter (ADC) family. The 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

synchronization. The ADC322x family 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-bit output data from

each channel. In addition to the serial data streams,

the frame and bit clocks are also transmitted as

LVDS outputs.
