SLES163A – MARCH 2006 – REVISED JULY 2006
TERMINAL
I/O
DESCRIPTION
NAME
NO.
Analog Section
AIP1A
2
I
Analog inputs for Channel 1. Connect to the video analog input via a 0.1-
F capacitor. The
AIP1B
3
maximum input range is 0–0.75 VPP, and may require an attenuator to reduce the input
amplitude to the desired level. If not used, connect to AGND via a 0.1-
F capacitor. Refer to
the schematic in Section 12.
AIP2A
11
I
Analog inputs for Channel 2. Connect to the video analog input via a 0.1-
F capacitor. The
AIP2B
12
maximum input range is 0-0.75 VPP, and may require an attenuator to reduce the input
amplitude to the desired level. If not used, connect to AGND via a 0.1-
F capacitor. Refer to
the schematic in Section 12.
AIP3A
22
I
Analog inputs for Channel 3. Connect to the video analog input via a 0.1-
F capacitor. The
AIP3B
23
maximum input range is 0-0.75 VPP, and may require an attenuator to reduce the input
amplitude to the desired level. If not used, connect to AGND via a 0.1-
F capacitor. Refer to
the schematic in Section 12.
AIP4A
31
I
Analog inputs for Channel 4. Connect to the video analog input via a 0.1-
F capacitor. The
AIP4B
32
maximum input range is 0-0.75 VPP, and may require an attenuator to reduce the input
amplitude to the desired level. If not used, connect to AGND via a 0.1-
F capacitor. Refer to
the schematic in Section 12.

Reference supply decoupling . Connect to analog ground through a 1-
F capacitor. Connect
125
to REFPx through a 1-
F capacitor.
REFPx
7, 18, 27,

99, 116
DVDD
46, 65, 81,
P
Digital power supply. Connect to 1.8-V digital supply.
98, 115
IOGND
44, 63, 79,
P
I/O power supply return. Connect to digital ground.
96, 113

FID1/GLCO1
94
O
1. FID: Odd/even field indicator or vertical lock indicator. For the odd/even indicator, a 1
FID2/GLCO2
75
indicates the odd field.
FID3/GLCO3
56
2. GLCO: This serial output carries color PLL information. A slave device can decode the
FID4/GLCO4
37
information to allow chroma frequency control from the TVP5154 decoder. Data is
transmitted at the CLK rate in Genlock mode.
AVID1
101
O
Active video indicator. This signal is high during the horizontal active time of the video
AVID2
78
output.
AVID3
59
AVID4
40
INTREQ1/GPCL1/VBLK1
102
I/O
1. Interrupt request : Open drain when active low.
INTREQ2/GPCL2/VBLK2
83
2. GPCL: General-purpose output. In this mode, the state of GPCL is directly programmed
INTREQ3/GPCL3/VBLK3
60
via I2C.
INTREQ4/GPCL4/VBLK4
41
3. VBLK: Vertical blank output. In this mode, the GPCL terminal is used to indicate the VBI
of the output video. The beginning and end times of this signal are programmable via I2C.
