GENERAL DESCRIPTION
AKIRA AKTP01 is a CTV monolithic chassis currently developed by AKIRA Co.
It introduces a monolithic IC TB1238AN developed by Toshiba Co. To carry out all the small signal
processing TB1238AN is a kind of IC used by color TV in PAL/NTSC system, which is controlled by
Inter IC Bus. Together with the SECAM decoder TA1275Z, it can form a signal processing circuit for
multi-system color TV. This chassis is used in many fashionable TV receiver technologies, which
makes the performance reach the advanced level of the world.
