AD9161 Datasheet Rf Digital-to-analog Converters

Manufacturer: Analog Devices

Overview: Data Sheet 11-Bit/16-Bit, 12 GSPS, RF Digital-to-Analog Converters AD9161/AD9162.

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.

Key Features

  • DAC update rate up to 12 GSPS (minimum) Direct RF synthesis at 6 GSPS (minimum) DC to 2.5 GHz in baseband 1× bypass mode DC to 6 GHz in 2× nonreturn-to-zero (NRZ) mode 1.5 GHz to 7.5 GHz in Mix-Mode Bypassable interpolation (1× or bypass mode) 2×, 3×, 4×, 6×, 8×, 12×, 16×, 24× Excellent dynamic performance.
