High Speed Multi-Channel ADC Clock Reference Design for Oscilloscopes, Wireless Testers and Radars

Overview

TopologyBuck Converter
Input voltage5-12 V
Output 13.6 V

Description

This TI Design demonstrates the performance of aclocking solution for a high-speed multichannelsystem, analyzed by measuring the channel-tochannelskew for the entire input frequency range ofthe RF sampling ADC. Channel-to-channel skew iscritical for phased array radar and oscilloscopeapplications. The ADC12J4000 is a low-power, 12-bit,4-GSPS RF-sampling analog-to-digital converter(ADC) with a buffered analog input, integrated digitaldown converter, features a JESD204B interface, andcaptures signals up to 4 GHz. This design showcasesthe clocking solution using the LMK04828 to achievethe synchronization between multiple ADC12J4000signal chains using synchronized SYSREF.
