7 GSPS) APPLICATIONS Broadband communications systems CMTS/VOD Wireless infrastructure: W-CDMA, LTE, point-to-point Instrumentation, automatic test equipment (ATE) Radar, jammers GENERAL DESCRIPTION The AD9119/AD9129 are high performance, 11-/14-bit RF digitalto-analog converters (DACs) supporting data rates up to 2.
85 GSPS.
The DAC core is based on a quad-switch architecture that enables dual-edge clocking operation, effectively increasing the DAC update rate to 5.
7 GSPS when configured for Mix-Mode™ or 2× interpolation.
The high dynamic range and bandwidth enable multicarrier generation up to 4.
2 GHz.
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 postreconstruction filter by effectively increasing the DAC update rate by a factor of 2.
In Mix-Mode operation, the AD9119/AD9129 can reconstruct RF carriers in the second and third Nyquist zone while still maintaining exceptional dynamic range up to 4.
2 GHz.
The high performance NMOS DAC core features a quad-switch architecture that enables industry-leading direct RF synthesis performance with minimal loss in output powe...
