AN5636K

SECAM/PAL signal conversion IC

■ Overview

The AN5636K is an IC which converts the SECAM
signal into the quasi-PAL signal. This IC can add the
SECAM signal processing function while rationalizing
the external parts in a joint use with the PAL/NTSC sig­nal processing IC: AN5606K.

■ Features

• Rationalizing IHDL in common use with PAL IHDL

• Lowering 6H line crawling by the quasi-PAL modula-

tion

• For both auto and manual modes of signal processing

■ Applications

• TV (applicable to three systems: PAL/NTSC/SECAM)
