6-6

(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.

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.

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

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

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.
