Design of high-speed data playback board based on AD9739

摘要

This paper gives a brief introduction of a high-speed playback board which has multi-channel synchronization function. FPGA is controller and AD9739 is playback chip. By choosing hardware and configuring software, the board can be used as single-channel, dual-channel, three-channel and four-channel data playback board. When the operating mode is selected as a channel with four paths, playback rate can be up to 10Gsps. Synchronization error between channels can be as small as 40ps. This paper focuses on the hardware and software implementation of target DA board.
