Datasheet Analog Devices AD9161 — 数据表

11-Bit/16-Bit, 12 GSPS,
RF Digital-to-Analog Converters
AD9161/AD9162 Data Sheet In baseband mode, wide bandwidth capability combines with
high dynamic range to support DOCSIS 3.1 cable infrastructure
compliance from the minimum of two carriers to full maximum
spectrum of 1.794 GHz. A 2Г— interpolator filter (FIR85) enables
the AD9161/AD9162 to be configured for lower data rates and
converter clocking to reduce the overall system power and ease
the filtering requirements. In Mix-Modeв„ў operation, the AD9161/
AD9162 can reconstruct RF carriers in the second and third
Nyquist zones up to 7.5 GHz while still maintaining exceptional
dynamic range. The output current can be programmed from
8 mA to 38.76 mA. The AD9161/AD9162 data interface consists
of up to eight JESD204B serializer/deserializer (SERDES) lanes
that are programmable in terms of lane speed and number of
lanes to enable application flexibility. FEATURES
