DOCSIS 3.1 Upstream Amplifier
The BGA3131 is an upstream amplifier meeting the Data Over Cable Service Interface Specifications (DOCSIS 3.1). It is designed for cable modem, CATV set top box and VoIP modem applications. The device operates from 5 MHz to 205 MHz. The BGA3131 provides 58 dB gain control range in 1 dB increments with high incremental accuracy. Its maximum gain setting delivers 37 dB voltage gain and a superior linear performance.
It supports the DOCSIS 3.1 output power levels while meeting the stringent ACLR requirements.
The BGA3131 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 interface 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 25 mA while it can be still programmed to new gain and current settings.
The BGA3131 is housed in 20 pins 5 mm x 5 mm leadless HVQFN package.
