Panasonic AN5422K Datasheet
ICs for TV
■ Overview
The AN5422K is an integrated circuit for TV/display
deflection-signal-processing circuit. Horizontal oscillation
frequency is up to 120kHz. The duty of a horizontal output pulse can be changed by the external bias so that the
display is designed easily.
■ Features
•
Noise canceller circuit built-in (with lock-out preventive
circuit)
•
The duty of a horizontal output pulse can be changed
by the external bias.
•
Horizontal oscillation frequency : max. 120kHz
•
X-ray protector built-in (shutdown)
•
Vertical drive circuit built-in
