TDA9181

Mode deﬁnitions

Table 1

General mode deﬁnitions; note 1

Note

1. If the OUTSEL pin is left open-circuit, the pin is pulled

LOW by means of an internal pull-down resistor to

analog ground (AGND). Thus the COMB mode can

also be selected by not connecting the OUTSEL pin.

Table 2

Y/CVBSOUT output signal deﬁnitions

Table 3

COUT output signal deﬁnitions

Table 4

Input switch mode deﬁnitions; note 1

Note

1. If the INPSEL pin is left open-circuit, the pin is pulled

LOW by means of an internal pull-down resistor to

analog ground (AGND). Thus the Y/CVBS1 input can

also be selected by not connecting the INPSEL pin.

Table 5

FSC mode deﬁnitions; note 1

Note

1. If the FSCSEL pin is left open-circuit, the pin is pulled

LOW by means of an internal pull-down resistor to

analog ground (AGND). Thus the fSC mode can also

be selected by not connecting the FSCSEL pin.

Table 6

Video standard mode deﬁnitions; note 1

Note

1. If the SYS1 and SYS2 pins are left open-circuit, the

SYS1 pin is pulled HIGH by means of an internal

pull-up resistor to analog supply (VCCA) and the SYS2

pin is pulled LOW by means of an internal pull-down

resistor to analog ground (AGND). Thus the NTSC M

video standard can also be selected by not connecting

pins SYS1 and SYS2.
