FMC DAC 600M 12b 1cha DDS
Project description
The FMC DAC 600M 12b 1cha DDS board can be used to distribute RF signals over the WR network:
Together with the Simple PCIe FMC Carrier - SPEC makes a complete WR RF distribution node.
Main Features
- Low-Pin Count FMC
- 14-bit 600MHz DAC with splitter and amplifier
- ADF4002 phase detector + programmable LPF + 16-bit ADC
- Clocking resources
- 1x 10-280 MHz I2C Programmable XO Oscillator, starts up at 100 MHz (Silicon Labs Si570, freely usable)
- 1x 25 MHz TCXO controlled by a DAC with SPI interface (AD5662, used by White Rabbit PTP core)
- 2x low-jitter frequency synthesizer/fanout
- 64kbit EEPROM (24AA64T-I/MC) connected for storing application parameters
- Miscellaneous
- On-board thermometer IC (DS18B20U+)
- 4-layer PCB
