8. DSP IC: ADSP-21065L(X08,IC21) CHECK METHOD
Note: This IC is scarcely damaged. Pay attention to poor soldering if replace it.
1. Set the selector to ANALOG(TAPE or TUNER). In this mode, Fs will be 48kHz.
2. Set the mode to JAZZ CLUB.
3. Check the square waveform which is 500Hz period at #76(FLG11) of IC. It is good if #76 has the waveform.
4. Check the waveform which is 30MHz at #30(CLKIN) of IC.
5. Check the voltage which is 3.3V at #157(RESET) of IC
6. Check the every ports which are 48MHz at #7(TFS0), #13(RFS1) and #18(TFS1) of IC
7. Check the every ports which are 3.07MHz at #8(TCLK0) and #15(RCLK1) of IC.
8. Check the waveform which are data at #16(DR1A) of IC. Refer to figures.
Check the AD converter and DIR and oscillation circuitry if you can get no good at above steps.
9. Check the waveform which are data at #11(DT0A), #12(DT0B) and #22(DT1A) of IC.
Check the DA converter and so if you can get step9, too.
