STV0297J
Universal digital cable demodulator
DATA BRIEF
Description
The STV0297J is a highly integrated device,
compliant with DVB-C/ITUJ83-A/B/C.
It provides a small footprint, low-power solution
enabling it to be easily integrated into broadcast
and interactive set-top boxes and network inteface
modules.
Furthermore, the STV0297J is the first QAM
demodulator with the integrated support for
transport stream multiplex frame required for
Japanese cable set-top boxes.
Application: Advanced solution for very low-cost broadcast and interactive cable set-top boxes
