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

1 января 2018

The TIDA-01017 reference design demonstrates the performance of a clocking solution for a high speed multi-channel system, analyzed by measuring the channel to channel skew for the entire input frequency range of the RF sampling ADC. Channel to channel skew is critical for phased array radar and oscilloscope applications. The ADC12J4000 is a low power, 12-bit, 4-GSPS RF-sampling analog to digital converter (ADC) with a buffered analog input, integrated digital down Converter, features a JESD204B interface, and it captures signals up to 4GHz. This design showcases the clocking solution using the LMK04828, to achieve the synchronization between multiple ADC12J4000 signal chains using synchronized SYSREF.
