C bus for HD, wide television
n Overview
The AN5491K is a deflection processor IC for syn-
chronous signal processing and screen distortion correc-
tion. It synchronizes with the input signal of High-vision,
wide television, NTSC, PAL and VGA by the external
binary input signal of them so that a multimedia television
can be realized easily.
n Features
• Supports the multiple-point horizontal frequency
(15.7 kHz to 62.7 kHz)
• Horizontal duty is controllable by external voltage.
• Built-in full functions for correction
(Horizontal and vertical: 16 items)
• Over-current detection, shut-down and hold-down
n Applications
• High-vision televisions, Wide screen televisions and
Projection televisions
