Rk2608 may realize video file decode playing of MPEG-4 format in low frequency and power consumption with clear and smooth picture quality, meanwhile, Rk2608 integrates large amount of I/O control jacks which may provide the max flexibility.

  • Page 23: Audio Decode Circuit Principle

    2. Working principle: when the machine power on, reset circuit keeps high level reset signal. After RK2608 completes reset through reset pin 113, reset signals output from pin 56 to pin 42 of SSD1928 to enable SSD1928 to finish reset (V3 screen need no SSD1928 drive, so there is no this reset process), at the same time reset signals are sent to enable end of RT9284, boost circuit begins to work and screen is lightened.

  • Page 25: Fm Tuning Circuit

    There is firmware of the player’s working inside Flash and all tasks are completed by CPU to send out relevant order after the data exchange between CPU and Flash. When the player power on, 3.3V voltage supplies power for Flash through VCC, /CE inputs 3.3V high level signal and Flash begins to work effectively.

  • Page 26: Display Screen Boost Circuit

    When MP3 player switches in FM tuning state, antenna is sent to the RF band-pass filter (87.6MHz~108MHz and 76MHz 87.5MHz) composed of Li6, C57 and C59 through C56 coupling and then to pin 35, 37 of TEA5767 for amplifying through TEA5767 inside. Pin 2, 3, 4 of TEA5767 is connected with the internal VCO and with variant diode D10, D11 externally.

    2. Working principle: when the player power on, voltage stabilizing circuit begins to work and 3.3V voltage VCC outputs. Voltage on two sends of capacitor C19 cannot change suddenly, so B electrode of triode Q3 is low level, Q3 is in cutoff state, RESETN is high level to reset for Rk2608 and display screen. Meanwhile, VCC charges capacitor C19.
