GENERAL DESCRIPTION
AKPH02 chassis series are applied in A14P01/A21P01 respectively which uses mainly
Philips’ advance UOC ultimate chip TDA935X/6X/8X and I2C-bus controlled IC. With
combination of microcontroller and small signal processor, the TDA935X/6X/8X series feature
high-integration, high performance-to-price ratio and high-reliability and advanced functions
with fewer external component, which provide much convenience for manufacturing and
technical service.
Figure 1: show the block diagram of AKPH01(A14P01/A21P01).
Table 1: Provides A14P01/A21P01 mainly ICs and functions.
Figure 2: Shows the whole set power supply system for AKPH01(A14P01/A21P01).
Figure 3: Shows the system control circuit of AKPH01 (A14P01/A21P01).
Table 1: A14P01/A21P01 mainly ICs and functions.
