Audio Interface
Horizontal Sync
HS is the horizontal sync signal from the PAL/NTSC
Encoder. HS is used to reset the horizontal counters in
the display controller. HS should be synchronous to
SYSCLK.
Vertical Sync/Odd-Even Field Indicator
VS is the vertical sync signal from the PAL/NTSC
Encoder. It can be programmed to be either a
conventional vertical sync input or an even/odd field
indicator. In the even/odd field indicator mode, the
internal display controller counters reset each time VS
changes state (at the beginning of each field). The
polarity of the field is controlled by the timing of VS
relative to HS. VS should be synchronous to SYSCLK.
Unencoded serial audio data from a CD or other storage
device. Connected directly to the ASDATA output when
the host selects the CD Bypass mode.
CD Mode DAC Bit Clock
Bit clock from CD player. Connected directly to the BCLK
output when the host selects the CD Bypass mode.
CD Mode DAC Left/Right Clock
Left/right sample clock from CD player. Connected
directly to the LRCLK output when the host selects the
CD Bypass mode.
CD Mode DAC Clock
DAC clock from CD player. Connected directly to the
A_ACLK output when the host selects the CD Bypass
mode.
Audio Serial Data
Serial audio data from the L64105’s Audio Decoder in
nonbypass modes. The data can be MPEG or Linear
PCM audio. Serial audio data from the CD_ASDATA input
in CD Bypass mode.
