FUNCTIONAL DESCRIPTION

FUNCTIONAL PIN DESCRIPTION

FUNCTIONAL DESCRIPTION

FUNCTIONAL PIN DESCRIPTION

VCC

VCC is the power input terminal for the IC. A 0.1

μF bypass

capacitor in series with a 4.7Ω resistor to ground should be

connected as close as possible to this pin to provide noise

immunity.

IN

IN is the video signal input terminal.

GND

GND is the ground terminal for the IC.

RFREQ

The operating bandwidth of the IC is set by the value of the

resistor between this terminal and ground. By selecting a

value for the RFREQ resistor between 9.0k

Ω and 108kΩ,the

bandwidth can be set for video applications ranging from

1080p to 480i.

OUT

OUT is the video signal output terminal.

EN

EN is a logic level enable input for the IC. EN = 1 turns the

IC on, and EN = 0 turns it off.
