描述 Description

The BGA3031 is an upstream amplifier meeting the Data Over Cable Service InterfaceSpecifications (DOCSIS 3.0). It is designed for cable modem, CATV set top box and VoIPmodem applications. The device operates from 5 MHz to 85 MHz. The BGA3031 provides58 dB gain control range in 1 dB increments with high incremental accuracy. Its maximumgain setting delivers 34 dB voltage gain and a superior linear performance.
It supports high output power levels, exceeding the DOCSIS 3.0 power levels whileminimizing distortion and output noise levels. The BGA3031 is capable of transmitting1 to 8 64-QAM and 1 to 8 QPSK modulated carriers while meeting the DOCSIS 3.0 ACLRspecification under DOCSIS 3.0 + 4 dB conditions.
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 enablesthe user to optimize between DC power efficiency and linearity. In addition the current isautomatically reduced at lower gain settings while preserving the linearity performance. Indisable mode the device draws typical 6 mA while it still can be programmed to new gainand current settings.
The BGA3031 is housed in 20 pins 5 mm x 5 mm leadless HVQFN package.
