Product specification

AM/FM stereo radio circuit

TEA5711; TEA5711T

FUNCTIONAL DESCRIPTION

The AM circuit incorporates a double balanced mixer, a

one pin low-voltage oscillator (up to 30 MHz) a

field-strength indicator output and is designed for

distributed selectivity.

The AM input is designed to be connected to the top of a

tuned circuit. AGC controls the IF amplification and for

large signals it lowers the input impedance.

The first AM selectivity can be an IFT as well as an IFT

combined with a ceramic filter; the second one is an IFT.

The FM circuit incorporates a tuned RF stage, a double

balanced mixer, a one-pin oscillator, a field-strength

indicator output and is designed for distributed IF ceramic

filters. The FM quadrature detector uses a ceramic

resonator.

The PLL stereo decoder incorporates a signal dependent

stereo circuit, a soft-mute circuit and a stereo indicator

LED driver.

Supply voltage behaviour

The TEA5711 incorporates internal stabilized power

supplies. The maximum supply voltage is 12 V, the

minimum voltage can go down temporarily to 1.8 V without

any loss in performance.

Due to the capacitor at pin 19 (RIPPLE) the IC gives

excellent performance, even when the actual supply

voltage at pin 25 (V

) drops below the voltage at pin 19

(RIPPLE).

Figures 4, 5 and 6 show that V

stab

, which is dominant for

the overall IC performance, remains unaffected, even if V

drops down to 1.8 V or less. In this typical example the

static or average V

is equal to 2.5 V. Dips in V

stab

appear

only when the peak-to-peak value of the AC-component of

2 V, i.e. when the dynamic value of V

drops down to

1.5 V for a short moment.
