CBM97D39 14 bit, 2.5 GSPS, RF analog-to-digital converter

The CBM97D39 is a 14-bit, 2.5 GSPS high performance RF digital to-analog converter (DAC)capable of synthesizing wideband signals from dc up to 3.0 GHz. Its DAC core features a quad switch architecture that provides exceptionally low distortion performance with an industry-leading direct RF synthesis capability. This feature enables multicarrier generation up to the Nyquist frequency in baseband mode as well as second and third Nyquist zones in mix mode. The output current can be programmed over the 8.66 mA to 31.66 mA range. The inclusion of on-chip controllers simplifies system integration. A dual-port, source synchronous, LVDS interface simplifies the digital interface with existing FGPA/ASIC technology. On-chip controllers are used to manage external and internal clock domain variations over temperature to ensure

reliable data transfer from the host to the DAC core. Multichip synchronization is possible with an on-chip synchronization controller. A serial peripheral interface (SPI) is used for deviceconfiguration as well as readback of status registers. The CBM97D39 is manufactured on a 0.18μm CMOS process and operates from 1.8 V and 3.3 V supplies. It is supplied in a 160-ball chip scale ball grid array for reduced package parasitics.
