ANALOG DEVICES 5 V CATV Line Driver Coarse Step Output Power Control AD8322 handbook
AD8322 is a low-cost, digitally controlled variable gain amplifier that supports DOCSIS standard for reverse path transmission gain. It can be programmed in 6 dB steps over a 42 dB range via SPI interface. At 60 dBmV output, the distortion is low, –58dBc SFDR@21MHz, –56dBc SFDR@42MHz. The output noise level is –46dBmV with a bandwidth of 180MHz. The supply voltage is 5V.

Questions answered in these manuals
What is the gain range of the AD8322?
The AD8322 provides a programmable gain range from 41.0 dB to 43.2 dB.
How is gain programmed in the AD8322?
Gain is programmed via an 8‑bit SPI interface using the DATEN, SDATA, and CLK pins.
What is the purpose of the AD8128?
The AD8128 is a high‑speed differential receiver/equalizer that compensates for the transmission losses of CAT‑5/UTP cables.
