NJW1321
WIDE BAND VIDEO SWITCH WITH I2C BUS
■ GENERAL DESCRIPTION
2
The NJW1321 is a Wide Band Video Switch with I C BUS.
The NJW1321 includes switch of 4-input 2-output and 6dB
amplifier. It is suitable for RGB or Y, Pb, and Pr signal because
frequency range is 100MHz.
The NJW1321 includes external logic control terminals and
external logic discernment terminals.
The NJW1321 is suitable for PTV, DTV, PDP and other high quality
AV systems.
