AD9129BBCZ

AD9129 is a high performance 14bit RF digital to-analogue converter supporting data rates up to 2.85GSPS. The DAC core is based on a quad-switch architecture that enables dual-edge clocking operation, effectively increasing the DAC update rate to 5.7GSPS when configured for Mix-Mode™ or 2× interpolation. The high dynamic range and bandwidth enable multicarrier generation up to 4.2GHz. In baseband mode, wide bandwidth capability combines with high dynamic range to support from 1 to 158 contiguous carriers for CATV infrastructure applications. A choice of two optional 2× interpolation filters is available to simplify the post reconstruction filter by effectively increasing the DAC update rate by a factor of 2. Application includes broadband communications systems, CMTS/VOD, wireless infrastructure: W-CDMA, LTE, point-to-point, instrumentation, automatic test equipment (ATE), radar, jammers.
