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.

Applications

! DOCSIS 2.0+ cable modem module

! Interactive cable set-top box

! eMTA terminal.
