amplitude to the desired level. If not used, connect to AGND via a 0.1- µ 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- µ F capacitor. The
AIP2B 12 maximum input range is 0-0.75 V
PP
, and may require an attenuator to reduce the input
amplitude to the desired level. If not used, connect to AGND via a 0.1- µ 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- µ F capacitor. The
AIP3B 23 maximum input range is 0-0.75 V
PP
, and may require an attenuator to reduce the input
amplitude to the desired level. If not used, connect to AGND via a 0.1- µ 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- µ F capacitor. The
AIP4B 32 maximum input range is 0-0.75 V
PP
, and may require an attenuator to reduce the input
amplitude to the desired level. If not used, connect to AGND via a 0.1- µ F capacitor. Refer to

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 I
2
C.
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 I
