FMC DAC 600M 12B 1CHA DDS

AvailableAsk

The FMC DAC 600M 12B 1CHA DDS is an FPGA expansion module for ultra-precise RF signal generation and distribution in White Rabbit networks. Paired with a SPEC card, it forms a complete RF distribution node, enabling sub-nanosecond synchronization with ultra-low jitter (<20 ps). It distributes clock and RF signals to multiple devices while maintaining time and phase coherence. Ideal for particle accelerators, time metrology, measurement systems, and advanced telecom networks. 

Technical Specifications

Applications

The module is designed to work with the Simple PCIe FMC Carrier – SPEC card and distributes periodic signals (primarily clock signals) of arbitrary frequencies across a White Rabbit network. In accelerator applications, it can be used for beam synchronization, RF clock distribution, and acquisition of RF or beam-synchronous signals.
