The CLK104 RF clock add-on card is designed for use with Zynq® UltraScale+™ RFSoC Gen3 ZCU216 and ZCU208 evaluation boards. It provides an ultra low-noise, wideband RF clock source for the analog-to-digital and digital-to-ananlog converters (ADCs and DACs).

The clock distribution PLL provides the low frequency reference clock for integrated PLL of RFSoC devices. RFSoC devices accept one RF sampling clock for all ADC channels and one RF sampling clock for all DAC channels. ADCs and DACs have dedicated RF PLLs physically located close to them. The CLK104 supports multi-tile and multi-board synchronization.
