1 System Description

The Cascaded Clock Distribution Reference Design uses multiple LMX1204 devices to distribute a single clock input to 16 clock outputs. The device operates up to 12.8GHz which supports high frequency clock distribution for high speed data converter applications. The design also provides 16 SysRef signals to data converters using the JESD204B digital interface protocol. There are 4 additional low speed clock outputs suitable for FPGA clocking. The design also incorporates options to divide-down or multiply-up the input clock signal. All outputs are synchronized to maintain deterministic latency within an array of data converter devices.
