Audio processor for VHS hi-ﬁ

TDA9615H

Table 22 Bit DOS; notes 1 and 2

Notes

1. An independent selection of TUNL and TUNR (pins 1 and 2), EXT1L and EXT1R (pins 5 and 6), SAP (pin 44) or

mute is possible for the decoder outputs DECL and DECR (pins 18 and 19) by setting bit DOS to 1. Source selection

is offered by using bits DOS1 and DOS0 of the select byte. These direct selections are also operable in ‘active

standby’ mode (STBA = 1 of the control byte).

2. In combination with the independent EXT2 selection to the outputs LINEL and LINER (pins 15 and 16) via bit LOS

full Euro-SCART pay-TV decoder switching is offered.

3. POR.

4. Internal mode.

Table 23 Bit RFCM; note 1

Notes

1. RF converter output RFCOUT (pin 12) can be muted using bit RFCM. During mute the AGC capacitor at pin 11

(RFCAGC) is discharged, resetting AGC control.
