			Table 1−1. Terminal Functions
TERMINAL		I/O	DESCRIPTION
NAME	NUMBER
Analog Video
VI_1_A	80	I/O	VI_1_A: Analog video input for CVBS/Pb/C or analog video output (see Section 2.11.59)
VI_1_B	1	I	VI_1_x: Analog video input for CVBS/Pb/C
VI_1_C	2	I	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
VI_2_C	9	I	Up to 10 composite, 4 S-video, and 2 composite or 3 component video inputs (or a combination thereof)
VI_3_A	16	I	can be supported.
VI_3_B	17	I	The inputs must be ac-coupled. The recommended coupling capacitor is 0.1 ∝F.
VI_3_C	18	I	The possible input configurations are listed in the input select register at I2C subaddress 00h (see
VI_4_A	23	I	Section 2.11.1).
Clock Signals
DATACLK	40	O	Line-locked data output clock
XTAL1	74	I	External clock reference input. It can be connected to an external oscillator with a 1.8-V compatible clock
			signal or a 14.31818-MHz crystal oscillator.
XTAL2	75	O	External clock reference output. Not connected if XTAL1 is driven by an external single-ended oscillator.
Digital Video
	57, 58,
C_[9:0]/	59, 60,		Digital video output of CbCr, C[9] is MSB and C[0] is LSB. Also, these terminals can be programmable
	63, 64,	I/O	general-purpose I/O.
GPIO[9:0]
	65, 66,		For the 8-bit mode, the two LSBs are ignored. Unused outputs can be left unconnected.
	69, 70
	43, 44,
	45, 46,		Digital video output of Y/YCbCr, Y[9] is MSB and Y[0] is LSB.
Y[9:0]	47, 50,	O
			For the 8-bit mode, the two LSBs are ignored. Unused outputs can be left unconnected.
	51, 52,
	53, 54
Miscellaneous Signals
GPIO	35	I/O	Programmable general-purpose I/O
GLCO/I2CA	37	I/O	Genlock control output (GLCO) uses real time control (RTC) format.
			During reset, this terminal is an input used to program the I2C address LSB.
INTREQ	30	O	Interrupt request
	14, 15,		Not connected. These terminals can be connected to power or ground (compatible with TVP5146
NC	19, 20,
			terminals), internally floating.
	21, 22
			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	I2C clock input
SDA	29	I/O	I2C data bus
