1 ICs for Cssette, Cssette Deck ANN, ANN Puse Detection s of Rdio Cssette, Cssette Deck Overview The ANN nd the ANN re the puse detection integrted circuits which select the progrm on the cssette tpe. In the ordinl method, tpe speed is different depending on the PLAY nd FF/REW, nd lso nonsignl time etween the progrms is different. Therefore, two time constnt circuit hs een pplied in order to detect ech time. The ANN nd the ANN re proud of detecting the progrm y mking the time corresponding to ech non signl time logiclly in the one time constnt circuit. Furthermore, signl cn e detected in this time constnt circuit nd eginning of the progrm is recognized when sound signl pulse increse more thn specified numers. Fetures Built-in protection circuit to prevent mis-opertion when power switch is turned ON. Time-constnt circuit for detection of no-signl period in PLAY nd FF/REW. No-signl period nd output pulse width cn e selected y externl cpcitor. Detection level of input signl cn e selected y externl resistor. As the ON/OFF input for mode setting nd puse detection, oth TTL level nd power source level cn e used. ery few externl components needed. Block Digrm.±0..0±0..±0..±0. Amp.
