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.
Module Features
• Low-Pin Count FMC module
• 14-bit DAC 600 MHz (MAX5890EGK+D) with fanout and amplifier
• Phase detector ADF4002 with programmable LPF and 16-bit ADC
• PLL AD9510 with external oscillator for RF signal jitter reduction
• 4-layer PCB
• Onboard temperature sensor IC (DS18B20U+)

• 2 status LEDs
Inputs / Outputs (LEMO 00)
• RF input 50 Ω (up to 500 MHz)
• RF output 50 Ω (up to 500 MHz)
• RMS jitter < 20 ps (V2 1 version)
• Split beam clock output (LVTTL)
• External trigger input (LVTTL)
• Synchronous RF trigger output with fine delay adjustment (LVTTL)
Clocking Resources
• 1× VCTCXO with user-defined frequency, controlled by PLL AD9510 (low-jitter)
• 1× TCXO 25 MHz controlled via DAC SPI interface (AD5662, used by White Rabbit PTP core)
• Low-jitter synthesizer/fanout (AD9516)
• Synchronous trigger output with beam clock and fine delay adjustment (SY89295)
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.
