Xilinx Zynq-7000 XC7Z020 + TI LMK04828 Clock Synchronization Board ADK-W104
Xilinx Zynq-7000 XC7Z020 + TI LMK04828 Clock Synchronization Board ADK-W104
The ADK-W104 is a high-performance, highly integrated clock synchronization board built around the Xilinx Zynq-7000 XC7Z020 SoC (dual-core ARM Cortex-A9 + FPGA) and the TI LMK04828 dual-PLL, ultra-low-jitter clock generator, providing up to 14 differential clock outputs through high-performance SMA connectors. Output frequencies are programmable from 0.1 Hz to 3 GHz with typical RMS jitter of 88 fs or less, and the board supports JESD204B Subclass 1 SYSREF generation and device clocking. A 122.88 MHz differential crystal and a 30.72 MHz TCXO provide the reference, and external reference input/output supports cascaded, coherent multi-board synchronization. The board delivers a clean, precisely synchronized clock source for demanding RF and digital systems, speeding the path from prototype to production.
