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.
