With bit AFM in register TNCTRL (see
audio pins maintain their functional impedance and DC-biasing level while the audio
signal is muted. The audio frequency mute is automatically activated during preset as well
as search tuning modes as shown in the flowchart of
The PLL stereo decoder is adjustment free. The stereo decoder can be switched to mono
via the control interface.
With decreasing RF input level the MPX decoder blends from stereo to mono to limit the
output noise. The continuous mono-to-stereo blend can also be programmed via the
control interface to an RF level depending on the switched mono-to stereo transition.
Stereo Noise Cancellation (SNC) can be switched on/off via the control interface using bit

One software programmable port (CMOS output) is available and can be controlled via
the control interface.
In software test mode the software port outputs signals according to
test mode is selected setting bit TM of register TESTREG. The software port is not
disabled by bit PUPD (see
With the Power-Up/Power-Down (PUPD) bit the radio can be put in Standby mode.
Standby mode is defined as where the TEA5760UK has all supply voltages available but
the circuits are powered down via software or after power-on reset. The TEA5760UK is
still accessible via the control interface, but takes only a very limited amount of power from
the supply. The software programmable port remains active to allow peripheral devices to
be controlled. The audio outputs are hard muted.
When pin BUSEN is HIGH and the circuits are powered down via software (PUPD) the
TEA5760UK is in Sleep mode. In Sleep mode the TEA5760UK is accessible via the
I
Standby mode.
When the supply voltage V
the audio outputs and the reference clock input are high-ohmic.
The power supplies can be switched on in any order.
