It supports up to four 192MHz-wide OFDM channels for downstream traffic, doubling the capacity of previous-generation DOCSIS 3.1 chips.
While optimized for DOCSIS 3.1, the BCM3392 maintains backward compatibility with DOCSIS 3.0 networks: broadcom 3392
The chip is built to handle heavy traffic in both directions. It supports along with eight single-carrier QAM upstream channels. This ensures that as user activity moves toward content creation and video conferencing, the network can handle the upstream demands efficiently. 3.
