APPLICATIONS
Broadband communications systems DOCSIS 3.1 cable modem termination system (CMTS)/ video on demand (VOD)/edge quadrature amplitude modulation (EQAM)
Wireless communications infrastructure W-CDMA, LTE, LTE-A, point to point
Instrumentation, automatic test equipment (ATE) Radars and jammers
GENERAL DESCRIPTION
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 2× 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-Mode™ 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 spe...
