SBAS671 ­ MAY 2014 ADC324x Dual-Channel, 14-Bit, 25 MSPS to 125 MSPS, Analog-to-Digital Converter
1 Features 1 3 Description
The ADC324x are a high-linearity, ultra-low power, dual-channel, 14-bit, 25-MSPS to 125-MSPS, analogto-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 while the SYSREF input enables complete system synchronization. The ADC324x family supports serial low-voltage differential signaling (LVDS) and JESD204B interfaces in order to reduce the number of interface lines, thus allowing for high system integration density. The serial LVDS interface is twowire, 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 14-bit output data from each channel. In addition to the serial data streams, the frame and bit clocks are also transmitted as LVDS outputs. Device Information(1)
