Pin Description
PIN
NAME
FUNCTION
1VAUD
Audio Supply. Connect to a 3.3V supply. Bypass with a 10F aluminum electrolytic capacitor in
parallel with a 0.1F ceramic capacitor to EP.
2
C1P
Charge-Pump Flying Capacitor Positive Terminal. Connect a 1F capacitor from C1P to C1N.
3
C1N
Charge-Pump Flying Capacitor Negative Terminal. Connect a 1F capacitor from C1P to C1N.
4
CPVSS
Charge-Pump Negative Power Supply. Bypass with a 10F aluminum electrolytic capacitor in
parallel with a 1F ceramic capacitor to EP.
5
DEV_ADDR
Device Address Set Input. Connect DEV_ADDR to GND, VVID, SDA, or SCL. See Table 3.
6
SDA
Bidirectional, I2C Data I/O. Output is open drain and tolerates up to 3.6V.
7
SCL
I2C Clock Input
8
ENC_B_IN
Encoder Blue Video Input
9
ENC_G_IN
Encoder Green Video Input
10
ENC_R/C_IN
Encoder Red/Chroma Video Input
11
ENC_CVBS_IN
Encoder Composite Video Input
12
TV_CVBS_OUT
TV SCART Composite Video Output. The sync tip is biased at 0.3V.
13
VVID
Video and Digital Supply. Connect to a +3.3V supply. Bypass with a parallel 1F and 0.1F
ceramic capacitor to GND. VVID also serves as a digital supply for the I2C interface.
14
TV_FS_OUT
TV SCART Fast-Switching Logic Output. This signal drives a back-terminated, 75 transmission
line.
15
GND
Video Ground
16
TV_R/C_OUT
TV SCART Red/Chroma Video Output. The black level of the red signal is set to 0.3V and the
blank level of the chroma signal is 1.5V.
17
TV_G_OUT
TV SCART Green Video Output. The black level of the green signal is set to 0.3V.
18
TV_B_OUT
TV SCART Blue Video Output. The black level of the blue signal is set to 0.3V.
19
V12
+12V Supply. Bypass V12 with a 0.1F capacitor to EP.
20
TV_SS_OUT
TV SCART Slow-Switch Signal Output
21
TV_OUTL
TV SCART Left-Channel Audio Output
22
ENC_INL+
Left Input-Amplifier Noninverting Terminal
23
ENC_INL-
Left Input-Amplifier Inverting Terminal
24
ENC_INLOUT
Left Input-Amplifier Output
25
ENC_INROUT
Right Input-Amplifier Output
26
ENC_INR-
Right Input-Amplifier Inverting Terminal
27
ENC_INR+
Right Input-Amplifier Noninverting Terminal
28
TV_OUTR
TV SCART Right-Channel Audio Output
—EP
Exposed Pad. The exposed pad is the internal ground for the audio amplifiers and charge pump.
A low-impedance connection to EP is required for proper isolation.
