DOCSIS 3.1 RF conditioner STB SoC White Box IP

OverviewFeaturesRequest Datasheet


This SOC white box IP extracted from the product chip. The RF signal conditioner for the front end of cable modems and gateways. The wideband path provides amplification, tilt compensation in the bandwidth 54 MHz to 1794 MHz. The RF signal conditioner amplifies and rectifies (performs tilt correction) the cable signal for cable modems and gateways. It can be used in cable multi-stream set-top boxes (STBs), cable gateways and DOCSIS 3.1/3.0 cable modems.
