AN3672NFBP
Audio signal processor IC for HiFi VCR incorporating EIAJ sound multiplex system
Unit: mm
s Overview
The AN3672NFBP is a HiFi audio signal processor IC (NTSC) incorporating EIAJ sound multiplex decoder and pre/recording amplifier. An adjustment-free sound multiplex decoder is realized through both of fO automatic adjustment of high precision VCO by a reference signal (fSC) and an SIF (4.5 MHz inter-carrier sound intermediate frequency) signal input.

6) Precautions on MTS application circuit (1) When an external input is selected with large amplitude noise into an input pin of television sound multiplex block, an appropriate signal to noise ratio is not always guaranteed. On use of SIF input, you can counter this problem by switching the setting from SIF to base band input through a serial control when using an external input. In this time, however, a timing control is required to return it to SIF in advance so as not to cause any shock noise which is likely to come out when HiFi input selector returns to television sound multiplex side. On use of a base band input, it is recommended that you perform muting outside to prevent from noise being inputted into television sound multiplex. (2) On use of television sound multiplex with a base band input, if you adjust an input level for 106 mV[rms] (= 300 mV[p-p]) with mono 100% modulation pre-emphasis off, the IC is in a state of an optimum separation. When you can not obtain an appropriate separation due to deviation of input signal frequency characteristics, however, you can adjust separation by fitting a volume of 100 k between pin 47 and GND. As the IC is already adjusted for an optimum separation with the above reference input, you can substitute the input level adjusting volume for a separation adjustment. In this case, do not forget to set pin 47 to open. (3) On use of sound multiplex with SIF input, an SIF input level from a tuner be set to 90 dBV 10 dBV against a typical RF electric field input. To get an appropriate separation without adjustment, you are required to use the flattest possible SIF-BPF band width that does not cause any delay time difference between main and sub in the range of 4.5 MHz 42 kHz. Likewise, use the gain band width which is broad enough not to attenuate cue signal carrier where a main component of 4.5 MHz 55 kHz. (4) In the tuner characteristics, a demodulation linearity must be set to 250% or more modulation to prevent the sub-carrier signal from being damaged by over-modulation of pre-emphasis in a higher band width. (5) The stereo modulator must be used with good characteristics and well-calibrated equipment at measurement of separation. When using SIF input, FM modulation factor must be tuned exactly so as to be 25 kHz at mono 100% modulation and pre-emphasis off. At the same time, measurement must be done by using the LPF which can attenuate 20 dB or more at 30 kHz between line-out and AC level-meter.
