(8-8) S Terminal DC Check
Color bar output by Video Encoder (IC252)
Error 11: Serial transfer error
The color bars are output in the same manner as in (8-2).
After VS signal is turned on/off repeatedly two times, the color
bar output is turned off.
(9) Audio Concerned
(9-2) Sampling Frequency 44.1kHz
16.9344MHz oscillation
Error 37: PLL DAC (IC209) serial transfer interruption is not de-
tected
Sampling frequency 44.1kHz is set to the PLL DAC (IC209).
If no error is found, the message is displayed to prompt for key
entry.
Observe the output waveform of IC209 (CXD8696R) SCK02 pin.
(9-3) Sampling Frequency 48kHz
18.4320MHz oscillation
Error 37: PLL DAC (IC209) serial transfer interruption is not de-
tected
Sampling frequency 48kHz is set to the PLL DAC (IC209).
If no error is found, the message is displayed to prompt for key
entry.
Observe the output waveform of IC209 (CXD8696R) SCK02 pin.
(9-4) Sampling Frequency 96kHz
36.8640MHz oscillation
Error 37: PLL DAC (IC209) serial transfer interruption is not de-
tected
Sampling frequency 96kHz is set to the PLL DAC (IC209).
If no error is found, the message is displayed to prompt for key
entry.
Observe the output waveform of IC209 (CXD8696R) SCK02 pin.
(9-5) Audio Digital Output
ROM audio data → ARP (IC806) → AV Decoder (IC203) → Digi-
tal audio I/F output
Error 10: ARP (IC806) → AV Decoder (IC203) data transfer
error
37: PLL DAC (IC209) serial transfer interruption is not de-
tected
AC-3-audio bit stream data stored in ROM (IC803) are transferred
to the AV Decoder (IC203) via ARP (IC806), and output to the
digital audio interface.
If no error is found, the message is displayed to prompt for key
entry.
Analog outputs are muted.
(9-6) Audio Digital Mute
ROM audio data → ARP (IC806) → AV Decoder (IC203) → Digi-
tal Audio I/F output
Error 10: ARP (IC806) → AV Decoder (IC203) data transfer
error
37: PLL DAC (IC209) serial transfer interruption is not de-
tected
AC-3-audio bit stream data stored in ROM (IC803) are transferred
to the AV Decoder (IC203) via ARP (IC806), and output to the
Digital Audio Interface. In such a case, the mute signal is turned
on/off alternately while the data are output 4 times.
1st time : Mute off Audible
2nd time : Mute on Not audible
3rd time : Mute off Audible
4th time : Mute on Not audible
If no error is found, the message is displayed to prompt for key
entry.
(9-7) MPEG Audio Analog Output
ROM audio data → ARP (IC806) → AV Decoder (IC203) → 2ch
DAC (IC215) → Analog audio output
Error 10: ARP (IC806) → AV Decoder (IC203) data transfer
error
35: 2ch DAC (IC215) serial transfer interruption is not de-
tected
37: PLL DAC (IC209) serial transfer interruption is not de-
tected
MPEG-audio bit stream data stored in ROM (IC803) are trans-
ferred to the AV Decoder (IC203) via ARP (IC806), and analog
audio data are output from 2ch DAC (IC215).
If no error is found, the message is displayed to prompt for key
entry.
(9-8) Dual DAC (Serial)
ROM audio data → ARP (IC806) → AV Decoder (IC203) → 2ch
DAC (IC215) → Analog audio output (Attenuation)
Error 10: ARP (IC806) → AV Decoder (IC203) data transfer
error
35: 2ch DAC (IC215) serial transfer interruption is not de-
tected
37: PLL DAC (IC209) serial transfer interruption is not de-
tected
MPEG-audio bit stream data stored in ROM (IC803) are trans-
ferred to the AV Decoder (IC203) via ARP (IC806), and they are
attenuated by 12dB (–12dB) in the 2ch DAC (IC215), then analog
audio data are output.
If no error is found, the message is displayed to prompt for key
entry.
