SPDIF out
Function
: Digital audio output
Signal
: SPDIFOUT
Type
: Output according to
IEC60958 or
IEC61937, 1Vp-p,
unbalanced.
1.3.3
Audio PCM (I2S format)
Function
: Digital audio
Signal
: DA_XCK, DA_BCK,
DA_LRCK,
DA_DATA0,
DA_DATA1,
DA_DATA2,
DA_DATA3
Type
: I2S output (33ohm
output resistors, in
series)
1.3.4
Analog Audio
Function
: Analog audio, 2-ch
Signal
: LT, RT
Type
: Analog output with on-
bd. 10k load
1.3.5
Audio mute
Function
: Audio mute control for
final analog stage
Signal
: MUTE
Type
: LVTTL output
Table 1-3
1.3.6
Analog video
Function
: Analog video
Signal
: CVBS_VID, C_VID,
Y_VID, R_VID (V),
G_VID (Y), B_VID (U)
Type
: Output (75ohm output
resistors, in series)
1.3.7
Slow blanking SCART
Function
: Slow blanking SCART
(0/6/12)
Signal
: SCART0, SCART1
Type
: LVTTL output
Table 1-4
Note: SCART0 & SCART1 are legacy features. They were
used to generate 0/6/12 signal on an ext. A/V bd. However,
most TV/Audio sets have their own Scart control ic & hence
these 2 pins have alternate functions via optional jumpers.
SCART1 shares with I2C_INT & GND; SCART0 pin shares
with SLOT_IN_DETECT.
1.3.8
Slave I2C
Function
: Slave I2C bus
(Hardware)
Signal
: S_I2C_CL;

Function
: Master I2C bus
(Software)
Signal
: M_I2C_CL;
M_I2C_DA
Type
: I2C
Note: I2C lines are pulled to +5V.
