Texas Instruments DAC38RF8x 14-Bit PLL Digital-to-Analog Converters

Texas Instruments DAC38RF8x 14-Bit PLL Digital-to-Analog Converters provide high performance, wide bandwidth, and RF sampling. The devices are capable of dual channel input data rate up to 3.33GSPS or single-channel operation with 8 bits up to 9GSPS. A low-power JESD204B interface is offered with up to 8 lanes, with a maximum bit rate of 12.5Gbps. The input interface is capable of data rates up to 3.33GSPS at 12-bits and 2.5GSPS at 16-bit resolution without interpolation in dual channel mode. The DAC38RF82 or DAC38RF89 can be used as a complex baseband transmitter with interpolation modes from 2x to 24x and is qualified for synthesizing wideband signals up to 2GHz bandwidth with 16-bit input resolution and 2.66GHz bandwidth with 12-bit input resolution. The DAC38RF82 and DAC38RF89 support different VCO frequency ranges.
