S U M M A R Y O F B E N E F I T S
The highest level of silicon integration ever achieved
for a DOCSIS/EuroDOCSIS cable modem, integrating
all the major silicon components of a cable modem
into a single device
The BCM3350 integrates all the silicon components of
a cable modem, resulting in dramatic overall system
cost reduction.
