Product data sheet
1. General description
The BGA3031 is an upstream amplifier meeting the Data Over Cable Service Interface
Specifications (DOCSIS 3.0). It is designed for cable modem, CATV set top box and VoIP
modem applications. The device operates from 5 MHz to 85 MHz. The BGA3031 provides
58 dB gain control range in 1 dB increments with high incremental accuracy. Its maximum
gain setting delivers 34 dB voltage gain and a superior linear performance. It supports
high output levels up to 67 dBmV while minimizing distortion and output noise levels.
The BGA3031 operates at 5 V supply. The gain is controlled via a 3-wire serial interface.
The current consumption can be reduced in 4 steps via the serial interface. This enables
the user to optimize between DC power efficiency and linearity. In addition the current is
automatically reduced at lower gain settings while preserving the linearity performance. In
disable mode the device draws typical 6 mA while it still can be programmed to new gain
and current settings.
The BGA3031 is housed in 20 pins 5 mm  5 mm leadless HVQFN package.
