There's a bit of mis information being conveyed about this one. What
Broadcom has done is to combine three chips into one chip.  That is,
the downstream demodulator, upstream modulator, and DOCSIS MAC into
a single chip. This does help the cost of goods scenario for
cable modems.  Cable modems however, are made up of many more additional
chips such as CPU, various memories, powersupply, glue logic, PIO, tuner,
analog power RF amplifier, vendor value add, etc.

Also, don't misread me on this.  The deployment success of cable
modems is heavily dependent on integration.  Having one chip replace
three is a significant step towards the goal of having a "one chip"
cable modem.
