 Check of AK4524 (IC5002) on M

    No problem when around 3MHz of rectangular wave (3.3Vpp) is output from the 13-pin
    SDTO. (The rectangular wave changes depending on the audio signal.)
    For the analog system, check the inputs (2 and 3pins) and the outputs (25 through 28pins). The
    outputs of these terminals change depending on the volume adjustments.

  • 

Check of AK4114 (IC5003) on M

    No problem when around 3MHz of rectangular wave (3.3Vpp) is output for the JL5003 [SPDIF].
    (The rectangular wave changes depending on the audio signal.)
    Check that 48kHz of rectangular wave (3.3Vpp) is supplied to the 24-pin LRCK. 

  •  

Check of  Display Signal Out (Black) 26pin

    The output signal level is about 3.3Vpp when the Display Signal Out terminals are not connected to 
    the Display unit.
    If the signals, SPDIF+/- and UART_O+/-, are output, no problem for the sending end.
    (When the Diplay Signal Out terminals are connected to the Display unit via display interface cable,
    the signal level is about 350mVpp since the signal is terminated at Display unit.)
    For receiving ends ( SIRCS input and UART input) the check can only be performed when the 

Display Signal.

    Out terminals are connected to the diplay unit.

 

    (Supply source: AK4524)
    Check that 3.072MHz of rectangular wave (3.3Vpp) is supplied to the 26-pin BICK. 
    (Supply source: AK4524)
