... A single 8-bit serial word selects one of four available supply current presets and one of sixty gain codes. The ADA4320-1 has been tailored to address both the high output drive and stringent fidelity requirements of DOCSIS 3.0. The part is able to maintain excellent adjacent channel rejection performance over the full 5 MHz to 85 MHz range, even with multiple bonded channels at maximum specified output levels ...

... APPLICATIONS INFORMATION GENERAL APPLICATIONS The ADA4320-1 is primarily intended for use as the reverse channel power amplifier (PA) in DOCSIS® 3.0 customer premises equipment (CPE), including cable modems, E-MTAs, and DOCSIS-enabled set-top boxes. The signals are typically QPSK or QAM waveforms generated by the upstream modulator and DAC. ...

... The ADA4320-1 exhibits optimum performance when driven with a balanced (differential) signal. OUTPUT BIAS, IMPEDANCE, AND TERMINATION The output stage of the ADA4320-1 requires a bias The 5 V power supply should be applied to the center tap of the output transformer through a 100 nH series inductor. This supply should also be decoupled with a 0.1 μ ...
Page 13
... The transformer should have minimal insertion loss over the 5 MHz to 85 MHz band and have a maximum dc current rating of at least 200 mA. Characterization of the ADA4320-1 was performed using a Coilcraft PWB-4-BL surface-mount wide-band RF transformer. Alternate choices for the output transformer are the Toko 458PT-1565 and the Tyco Electronics (M/A-COM) ABACT0018 ...
