Description
The STV0498 is a cable front-end solution for
interactive and PVR set-top boxes.
Built around a powerful 450-DMIP processor
there are three QAM demodulators with FEC, a
DOCSIS modem supporting full DOCSIS2.0
operations and channel bonding up to 120 Mbit/s.
The STV0498 supports both IPV4 and IPV6
protocols.
Ethernet and USB2.0 interfaces provide low-cost
connections to the host computer.
