Example for receiving a channel at 100.1 MHz:
The result must always be rounded to the lowest integer value. If rounded down to the
lowest integer value of N
Via the control interface this value can be written to register FRQSET and the
TEA5760UK will then start an autonomous search beginning at this frequency or go to a
preset channel at this frequency. When the application is built according the application
diagram (see
to the new frequency within 40 ms.
The PLL is triggered by writing one of the following bytes: FRQSETMSB, FRQSETLSB,
TNCTRL1, TNCTRL2, TESTBITS and TESTMODE.
Accurate validation of the PLL locking onto the new frequency can take 40 ms. Bit LD in
register TUNCHK (see
The TEA5760UK can be switched to the Japanese FM band or the US/Europe FM band.
With bit BLIM in register TNCTRL (see
FM band (87.5 MHz to 108 MHz), while setting bit BLIM to logic 1 enables the Japanese
FM band (76 MHz to 90 MHz).
The RF AGC prevents overloading and limits the amount of intermodulation products
created by strong adjacent channels. The default setting for the RF AGC is on and it can
be turned off via the control interface. The TEA5760UK also has an inband AGC to
prevent overloading by the wanted channel itself. The inband AGC is always on.
Fully integrated IF filter with a center frequency of 225 kHz.
Fully integrated FM quadrature demodulator.
