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.
