Part Name(s) : TDA7088 UTC
Unisonic Technologies
Description : FM RECEIVER CIRCUIT FOR BATTERY SUPPLY View

DESCRIPTION
The UTC TDA7088 is a bipolar integrated CIRCUIT FOR use in mono portable and pocket radios. It is used when a minimum of peripheral components (of small dimensions and low costs) is important. The CIRCUIT contains a frequency-locked loop(FLL) system with an Intermediate frequency (IF) of about 70kHz. Selectivity is achieved by active  RC-filters. De tuning related to the IF and  too weak input signals is suppressed by the mute CIRCUIT.

FEATURES
*Equipped with all stages of a mono RECEIVER from antenna to
audio output.
*Mute CIRCUIT
*Search tuning with a single varicap diode
*Mechanical tuning with integrating AFC
*AM application supported
*Power SUPPLY polarity protection
*Power SUPPLY voltage down to 1.8V

Part Name(s) : TEA5594 Philips
Philips Electronics
Description : AM/FM radio RECEIVER CIRCUIT View

GENERAL DESCRIPTION
The TEA5594 is a 32-pin integrated radio CIRCUIT designed FOR use in all Electronic Tuned Radio (ETR) sets especially those sets which have to fulfil the immunity requirements of CENELEC.
The AM CIRCUIT incorporates:
• A double balanced mixer
• A ‘one-pin’ oscillator with amplitude control operating in the LW/MW frequency range
• An IF amplifier and AM detector
• An AGC CIRCUIT which controls the IF amplifier and mixer

The FM CIRCUIT incorporates:
• A front-end (fulfilling the “out of band” CENELEC requirements)
• Two IF amplifiers (FOR distributed selectivity)
• A quadrature demodulator with a ceramic filter

The TEA5594 also contains:
• Oscillator output buffers FOR AM and FM
• A combined AM/FM IF counter output buffer with counter “enable” function
• A field strength level detector FOR AM and FM
• A soft mute CIRCUIT at FM, adjustable
• An extra IF amplifier to split up IF filtering

Features
• Low distortion on FM
• AM/FM level/indicator CIRCUIT
• A DC AM/FM switch facility
SUPPLY voltages 2.7 to 15 V
• A local distance switch facility (LOCAL-DX) at FM
• All pins are ESD protected

Part Name(s) : TEA5591A Philips
Philips Electronics
Description : AM/FM radio RECEIVER CIRCUIT View

GENERAL DESCRIPTION
The TEA5591A is a 24-pin integrated radio CIRCUIT, derived from the TEA5591 and is designed FOR use in AM/FM portable radios and clock radios. The TEA5591A differs from the TEA5591 in that it has:
    • Separate IF input pins FOR AM and FM

    • An LED driver indicator

The main advantage of the TEA5591A is its ability to operate over a wide range of SUPPLY voltages (1.8 to 15 V) without any loss of perFORmance.
The AM CIRCUIT incorporates:
    • A double balance mixer
    • A ‘one-pin’ oscillator with amplitude control operating in the 0.6 to 30 MHz frequency range
    • A split-up IF amplifier
    • A detector
    • An AGC CIRCUIT which controls the IF amplifier and mixer.

The FM CIRCUIT incorporates:
    • An RF input amplifier
    • A double balanced mixer
    • A ‘one-pin’ oscillator
    • Two IF amplifiers (FOR distributed selectivity)
    • A quadrature demodulator FOR a ceramic filter
    • Internal AFC
