"The AD9129 RF D/A converter utilizes ADI's patented quad-switch
architecture to synthesize the full dc-to-1.4 GHz baseband output
spectrum, which will greatly simplify and improve downstream DOCSIS
3.0-compliant transmitter design," said
More About the AD9129 14-bit RF D/A Converter
The AD9129 RF D/A converter enables industry leading direct RF synthesis performance with minimal loss of output power across its output spectrum. The device also enables dual-edge clocking operation, effectively increasing the converter update rate to 5.6 GSPS when configured for Mix-Mode or 2× interpolation mode. Its high dynamic range and bandwidth enable multicarrier generation up to 4.2 GHz. The device dissipates only 1.1 W at the full 2.8-GSPS D/A converter update rate.
The AD9129 includes a dual-port, source-synchronous LVDS (low-voltage differential signaling) interface that simplifies the data interface to a host FPGA or ASIC. On chip DLLs (delay-locked loops) optimize timing between different clock domains, while an SPI (serial peripheral interface) is used to configure the AD9129 and monitor the status of read-back registers.
