(adjust using external parts so that the voltage does not exceed 0.6 v.) (2) sereo mono switching (note 1 ) pin 1 5: connect the lpf2 pin to gnd. (adjust using external parts so that the voltage does not exceed 0.6 v.) note 1: when stereo/fm is selected, the multiplex vco frequency changes due to 0. 1 a flow. (3) if out on switching pin 9: when the voltage on the if out/req pin is set to 1 .3 v or below (v stb (2 v) ? vbe (0.7 v)) and about 500 a current flows, switch to on. toshiba recommends a load of 2.2 k ? .
ta2099n/f 2001-12-19 9 4. external change function ( 1 ) narrowband detector: when the fm if input signal is off-center, 1 0.7 mhz, by a few khz, the detector turns tun-led off. pin 2: adjusts bandwidth using the resistor of the fm bw pin. in combination with the c 2 pin, the r 2 pin configures an hpf. the smaller the pin 2 capacitance, the higher the hpf cutoff. note that when low-frequency sound is input, although tuning is maintained, the detector may turn tun-led off. (2) led on sensitivity adjustment pin 3: uses the fm vl sens pin resistor value to change the on sensitivity of tun-led. (3) if counter output sensitivity adjustment (note 2) pin 5: uses the fm s. sens pin resistor value to change the sensitivity of the if count output at if count on. note 2: for the led on sensitivity, (2) and (3) are linked. at if count on (connect resistor for pin 9 to gnd), the internal current depending on the pin 5 resistor value changes the if amp gain, the s meter startup, and the if input level (sensitivity). the led on sensitivity turns the led on by comparing the voltage which depends on the pin 3 resistor value with the s meter voltage. the change in s meter startup (sensitivity) at if count on causes the led on sensitivity set at if count off to change. therefore, confirm the led on sensitivity according to the seek operation specification. (4) blender control pin 1 4: changes the mpx l and r signal separation according to the input level set by the resistance. 5. others ( 1 ) v stb pin 22: set to 2 v internally. (2) quad pin 20: supports both a ceramic discriminator and a detector coil for quad. see 1 , in description of operation. note that when a detector coil is used, s/n and the skew ratio deteriorates. (3) l, r output pins 1 2, 1 3: l-out and r-out pins are used for current output. the external resistor is set to output impedance. this is specified when the load is 5. 1 k ? and 0.0 1 f. (4) agc pin 7: also used as the fm s meter.
