  • Page 19: Section Two Unit Circuit Principle

    Section Two Unit Circuit Principle 3.2.1 Servo circuit 1. DV727SI adopts SANYO 62 decoder and MTK decode solution (MT1389+FLASH(16M)+SDRAM (64M)). The servo circuit is mainly composed of front signal processing, digital servo processing, signal processing IC T1389 and drive circuit D5954, in which MT1389 is the main component of decode circuit at the same time.
  • Page 20 2. Working principle: after powering on or disc in, according to IOA signal, disc identification circuit decides through which path of variable resistor the laser detecting diode gets path to the ground, meanwhile MT1389 decides whether DVD laser or VCD laser is emitted according to IOA signal, which can be fulfilled through laser power control circuit.

    Analog channel to make the switching tube and make audio signal bypass into ground to reach the Purpose of mute. The working mechanism is that when no audio signal comes to a certain path, CS4360 changes the mute control signal corresponding with this path to high level. After pressing MUTE button, 3-path mute signals all change to high level.

  • Page 24: Power Supply Circuit

    2. Working principle: after power on, Dv33 voltage increases to 3.3V quickly, main chip power supply is normal, because the voltage to ground of C271, C272 cannot change suddenly, the input end of U205C shows low electric potential, now reset signal URST keeps low level to perform reset to main chip.
  • Page 25 2. Working principle: this power circuit is responsible for the module circuit power supply of this player. Working principle of each part is shown as follows: (1) Electromagnetic disturbance filter circuit: for various electromagnetic radiation exist outside, the input AC will be affected. The function of electromagnetic disturbance filter capacitor is to filter these disturbance to make those that enter bridge rectification circuit are pure 220V AC.
