AD9789 - 14-Bit 2400 MSPS RF DAC

Datasheet Summary

Description

The AD9789 is a flexible QAM encoder/interpolator/upconverter combined with a high performance, 2400 MSPS, 14-bit RF digitalto-analog converter (DAC).

Features

  • DOCSIS 3.0 performance: 4 QAM carriers ACLR over full band (47 MHz to 1 GHz).
  • 75 dBc @ fOUT = 200 MHz.
  • 72 dBc @ fOUT = 800 MHz (noise).
  • 67 dBc @ fOUT = 800 MHz (harmonics) Unequalized MER = 42 dB On chip and bypassable 4 QAM encoders with SRRC filters, 16× to 512× interpolation, rate converters, and modulators Flexible data interface: 4, 8, 16, or 32 bits wide with parity Power: 1.6 W (IFS = 20 mA, fDAC = 2.4 GHz, LVDS interface) Direct to RF synthesis support with fS mix.
