TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA7792P, TA7792F AM/FM 1 CHIP TUNER SYSTEM IC (1.5V USE) The TA7792P, TA7792F are AM/FM 1 chip tuner system TA7792P (FM FRONT END +AM/FM IF) ICs, which are designed for low voltage operation (1.5V, 3.0V). Those are especially > suitable for stereo headphone radio and radio cassette _- — recorder equipments. These item can realize the low SR ee pavn) power dissipation and few external parts. i \\ Wy \\ |) } |

The output impedance of pin ® is about 3000, due to match the impedance of the ceramic filter. Kar aaptl Mix (Note) > jour The spurious characteristic is determined by the fon age 23 vy a ) COME characteristic of the ceramic filter (10.7MHz), because 8 the mixer coil is dispensable. It is possible to a0) improve the spurious characteristic that the two ceramic filters of different characteristics are Fig.2 connected in series. '9- @ IF limiter amplifier (See Fig.3) The IF limiter amplifier is composed of six emitter- grounded amplifiers and a differential amplifier. The basis composition of the emitter-grounded amplifiers is 1K. shown as Fig.3. @ Detector circuit This stage is composed of the quadrature detector Fig.3 circuit, which has double balanced. 961001EBA2"

<AM SECTION> 6 @ RF amplifier (See Fig.4) plifier ( ig.4) } [ Lose This stage is composed of emitter-grounded amplifier, the input impedance of which has about 7.3kQ. L. | It is necessary to connect as Fig.4, because the a ws Qa condenser, Cj is available to the audio by-pass of the 15k RF-AGC, the noise of low frequency. @ Cy 22uF @ Mixer circuit = The amplified RF signal is transformed into IF signal Fae osha by the mixer circuit, which is composed of a differential amplifier. Fig.4 @ IF amplifier This stage is composed of four emitter-grounded amplifiers and the two differential amplifiers. The input impedance is rather high, because it is changed by the amplitude of input signal (AGC level). So the input terminal of the IF amplifier must be matched with the impedance of ceramic filter. <COMMON SECTION> @ AM/FM mode switchover Switchover between AM/FM mode is possible with one-make switch. In case of the opened, this IC has AM mode. Another in case that the terminal is connected to Vcc directly, that has FM mode. And the terminal of pin@ is Vcc terminal of FM FRONT END section, too. © Output circuit (See Fig.5) Both of the AM/FM detector signal is appeared Q a through the pin®. TA7792P / F }—@) TO TA7766AF Those output are chosen by the mode switchover. At “78 the same time, the output impedance is changed as follow at AM/FM mode, due to cut the AM carrier Fig.5 signal and pass the FM composite signal smoothly, with only one condenser. Rout (AM) = 8kQ (Typ.) Rout (FM) = 1-4kQ (Typ.) 1997-07-07 3/9
