NJW1328
Multi Input Wide Band Video Interface with I2C Control
!GENERAL DESCRIPTION
NJW1328 is a multi input wide band video interface IC with
I2C control. Also the NJW1328 includes 7-input 2 channel
video switch for CVBS, isolation amplifier for CVBS, 3-input 1
channel video switch for Component Video Signal, 2 channel
75-ohm driver for CVBS and 1 channel 75-ohm driver for
Component Video Signal. NJW1328 is suitable for video
equipment that has multi input and multi output.
