GENERAL DESCRIPTION
2
The
NJW1320
is a Wide Band Video Switch with I C BUS.The
NJW1320
includes switch of 4-input 3-output and 6dB amplifier. It is
suitable for Y, Pb, and Pr signal because frequency range is
50MHz.The
NJW1320
includes external logic control terminals and
external logic discernment terminals. The
NJW1320
is suitable for
PTV, DTV, PDP and other high quality AV systems.
