• Manufacturer Part Number: sm5330af
• Description: 3-channel Video Filter With Built-in 4-system Switch
• Manufacturer: Nippon Precision Circuits Inc, (NPC)

SUB ADDRESS: 01h − Input mode setting
Sets the video signal input pin operating mode.
SUB ADDRESS: 02h − Input switch select, I/O output control
Sets the video signal input switching and logic I/O pin output settings. The input can be switched between 4
systems (3-channels). This setting also determines the system that performs status register D-terminal discrim-
ination. The I/O_0 and I/O_1 pins are n-channel MOS open-drain outputs. When the I/O pins are used as
inputs, these bits are set to “1” so that the output is high impedance.
