STV0297J
Universal digital cable demodulator
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
