TDA9143

INPUT SIGNALS

Table 5

Source select; note 1

Note

1. When ECMB = 1 and no current is drawn from the

Fscomb pin, source select is forced to be YC.

Table 6

Trap bypass; note 1

Note

1. The chrominance trap is always bypassed in YC

mode.

ϕ1 loop control

Table 14 Forced standard; note 1

Note

1. If XA and XB indicate that only one crystal is

connected to the IC and FM and FRQF force it to use

the second crystal, then colour will be switched off.

When SAF = 0, SECAM 60 Hz is disabled; when

SAF = 1, SECAM 60 Hz is enabled.
