7 / 92 page TVP5154A www.ti.com SLES214C – DECEMBER 2007 – REVISED SEPTEMBER 2010 2.3 Terminal Functions TERMINAL 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 VPP, 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 VPP, 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 VPP, 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 VPP, 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. 8, 15, 19, AVDD P Analog power supply. Connect to 1.8-V analog supply. 28, 127 9, 16, 20, AGND 29, 35, G Analog power supply return. Connect to analog ground. 128 1, 10, 21, AIxGND G Analog input signal return. Connect to analog ground. 30 5, 14, 25, PLL_GND G PLL power supply return. Connect to analog ground. 34 4, 13, 24, PLL_VDD P PLL power supply. Connect to 1.8-V analog supply. 33 6, 17, 26, Reference supply decoupling . Connect to analog ground through a 1-µF capacitor. Connect REFMx I 125 to REFPx through a 1-µF capacitor. 7, 18, 27, Reference supply decoupling . Connect to analog ground through a 1-µF capacitor. Connect REFPx I 126 to REFMx through a 1-µF capacitor. Digital Section 47, 66, 82, DGND G Digital power supply return. Connect to digital ground 99, 116 46, 65, 81, DVDD P Digital power supply. Connect to 1.8-V digital supply. 98, 115 44, 63, 79, IOGND G I/O power supply return. Connect to digital ground. 96, 113 45, 64, 80, IOVDD P I/O power supply. Connect to 3.3-V digital supply 97, 114 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 I2C. 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 I2C.
