Product specification

TEA5768HL

The software programmable output (SWPORT1) can be

programmed to operate as a tuning indicator output.

As long as the IC has not completed a tuning action,

pin SWPORT1 remains LOW. The pin becomes HIGH,

when a preset or search tuning is completed or when a

band limit is reached.

The reference frequency divider of the synthesizer PLL is

changed when the MSB in byte 5 is set to logic 1. The

tuning system can then be clocked via pin XTAL2 at

6.5 MHz.

8.1.2 POWER-ON RESET

At Power-on reset the mute is set, all other bits are set to

LOW. To initialize the IC all bytes have to be transferred.
