I/O DESCRIPTION
NAME NO.
Analog Section
Analog inputs for Channel 1. Connect to the video analog input via a 0.1-µF capacitor. The
AIP1A 2 maximum input range is 0–0.75 V
PP
, and may require an attenuator to reduce the input
I
AIP1B 3 amplitude to the desired level. If not used, connect to AGND via a 0.1-µF capacitor. See the
schematic in Section 10.
Analog inputs for Channel 2. Connect to the video analog input via a 0.1-µF capacitor. The
AIP2A 11 maximum input range is 0-0.75 V
PP
, and may require an attenuator to reduce the input
I
AIP2B 12 amplitude to the desired level. If not used, connect to AGND via a 0.1-µF capacitor. See the
schematic in Section 10.
Analog inputs for Channel 3. Connect to the video analog input via a 0.1-µF capacitor. The
AIP3A 22 maximum input range is 0-0.75 V
PP
, and may require an attenuator to reduce the input
I
AIP3B 23 amplitude to the desired level. If not used, connect to AGND via a 0.1-µF capacitor. See the
schematic in Section 10.
Analog inputs for Channel 4. Connect to the video analog input via a 0.1-µF capacitor. The
AIP4A 31 maximum input range is 0-0.75 V
PP
, and may require an attenuator to reduce the input
I
AIP4B 32 amplitude to the desired level. If not used, connect to AGND via a 0.1-µF capacitor. See the
schematic in Section 10.

1. FID: Odd/even field indicator or vertical lock indicator. For the odd/even indicator, a 1
FID1/GLCO1 94
indicates the odd field.
FID2/GLCO2 75
O 2. GLCO: This serial output carries color PLL information. A slave device can decode the
FID3/GLCO3 56
information to allow chroma frequency control from the TVP5154A decoder. Data is
FID4/GLCO4 37
transmitted at the CLK rate in Genlock mode.
AVID1 101
AVID2 78 Active video indicator. This signal is high during the horizontal active time of the video
O
AVID3 59 output.
AVID4 40
1. Interrupt request : Open drain when active low.
INTREQ1/GPCL1/VBLK1 102
2. GPCL: General-purpose output. In this mode, the state of GPCL is directly programmed
INTREQ2/GPCL2/VBLK2 83
via I
2
C.
I/O
INTREQ3/GPCL3/VBLK3 60
3. VBLK: Vertical blank output. In this mode, the GPCL terminal is used to indicate the VBI
INTREQ4/GPCL4/VBLK4 41
of the output video. The beginning and end times of this signal are programmable via
I
