Pin Description
PIN
NAME
FUNCTION
1
V_DIG
Digital Supply Voltage. Connect to 5V.
2
DEV_ADDR
Device Address Set Input. Connect to G_DIG to set write and read addresses of 94h and 95h,
respectively. Connect to V_DIG to set write and read addresses of 96h and 97h, respectively.
3
SDA
Bidirectional Data I/O. I
2C-compatible, 2-wire interface data input/output. Output is open drain.
4
SCL
Clock Input. I
2C-compatible, 2-wire interface clock.
5
INTERRUPT_OUT
Interrupt Output. INTERRUPT_OUT is an open-drain output that goes high impedance to
indicate a change in the slow switch lines, AUX_SS, TV_SS, or VCR_SS.
6
G_DIG
Digital Ground
7
ENC_L_IN
Digital Encoder Left-Channel Audio Input
8
ST_AUX_IN
Satellite Dish Tone Input
9
ENC_R_IN
Digital Encoder Right-Channel Audio Input
10
AUD_BIAS
Audio Input Bias Voltage. Bypass AUD_BIAS with a 10F capacitor and a 0.1F capacitor to
G_AUD.
11, 22, 30
V_AUD
Audio Supply Voltage. Connect all V_AUD together. An on-board linear regulator creates the
+8V audio supply voltage from V12. Bypass pin 30 with a 10F aluminum electrolytic capacitor
in parallel with a 0.47F low-ESR ceramic capacitor to audio ground, and bypass pins 11 and
22 with 0.1F capacitors to audio ground.
12
AUX_L_IN
AUX SCART Left-Channel Audio Input
13
AUX_R_IN
AUX SCART Right-Channel Audio Input
14
VCR_R_IN
VCR SCART Right-Channel Audio Input
15
VCR_L_IN
VCR SCART Left-Channel Audio Input
16
TV_R_IN
TV SCART Right-Channel Audio Input
Typical Operating Characteristics (continued)
(VV12 = 12V, VV_VID = 5V, VV_DIG = 5V, 0.47F ceramic X5R capacitor in parallel with a 10F aluminum electrolytic capacitor from
V_AUD to G_AUD, no load, TA = +25°C, unless otherwise noted.)
