1.8 Terminal Functions
Table 1-1. Terminal Functions
TERMINAL
I/O DESCRIPTION
NAME NO.
Analog Video
VI_1_A 80 I/O
VI_1_B 1 I
VI_1_A: Analog video input for CVBS/Pb/C or analog video output (see Table 2-79)
VI_1_C 2 I
VI_1_x: Analog video input for CVBS/Pb/C
VI_2_x: Analog video input for CVBS/Y
VI_2_A 7 I
VI_3_x: Analog video input for CVBS/Pr/C
VI_2_B 8 I
VI_4_A: Analog video input for CVBS/Y
Up to ten composite, four S-video, and two composite or three component video inputs (or a
VI_2_C 9 I
combination thereof) can be supported.
VI_3_A 16 I
The inputs must be ac-coupled. The recommended coupling capacitor is 0.1 µF.
The possible input configurations are listed in the input select register at I
2
C subaddress 00h
VI_3_B 17 I
(see Table 2-12).
VI_3_C 18 I
VI_4_A 23 I
Clock Signals
DATACLK 40 O Line-locked data output clock
External clock reference input. It can be connected to an external oscillator with a 1.8-V
XTAL1 74 I
compatible clock signal or a 14.31818-MHz crystal oscillator.
External clock reference output. Not connected if XTAL1 is driven by an external single-ended
XTAL2 75 O
oscillator.
Digital Video
57, 58, 59, Digital video output of CbCr, C[9] is MSB and C[0] is LSB. C_0 and C_[9-2] can be used as
60, 63, 64, programmable general purpose I/O. C_1 (pin 69) requires an external pulldown resistor and
C_[9:0] I/O
65, 66, 69, should not be used for general purpose I/0.
70 For the 8-bit mode, the two LSBs are ignored. Unused outputs can be left unconnected.
43, 44, 45,
46, 47, 50, Digital video output of Y/YCbCr, Y[9] is MSB and Y[0] is LSB.
Y[9:0] O
51, 52, 53, For the 8-bit mode, the two LSBs are ignored. Unused outputs can be left unconnected.
54
Miscellaneous Signals
GPIO 35 I/O Programmable general-purpose I/O
Genlock control output (GLCO) uses real time control (RTC) format.
GLCO/I2CA 37 I/O
During reset, this terminal is an input used to program the I
2
C address LSB.
INTREQ 30 O Interrupt request
14, 15, 19,
Not connected. These terminals can be connected to power or ground (compatible with
NC 20, 21, 22,
TVP5146 terminals), internally floating.
24, 25
Power down input:
PWDN 33 I 1 = Power down
0 = Normal mode
RESETB 34 I Reset input, active low (see Section 2.8)
Host Interface
SCL 28 I I
2
C clock input
SDA 29 I/O I
2
C data bus
Power Supplies
AGND 26 Analog ground. Connect to analog ground.
A18GND_REF 13 Analog 1.8-V return
A18VDD_REF 12 Analog power for reference 1.8 V
CH1_A18GND 79 Analog 1.8-V return
CH2_A18GND 10
CH1_A18VDD 78 Analog power. Connect to 1.8 V.
