ICs for Cassette, Cassette Deck

s Overview

The AN6262N and the AN6263N are the pause detec-

tion integrated circuits which select the program on the

cassette tape. In the ordinal method, tape speed is differ-

ent depending on the PLAY and FF/REW, and also non-

signal time between the programs is different. Therefore,

two time constant circuit has been applied in order to

detect each time. The AN6262N and the AN6263N are

proud of detecting the program by making the time corre-

sponding to each non signal time logically in the one time

constant circuit. Furthermore, signal can be detected in

this time constant circuit and beginning of the program is

recognized when sound signal pulse increase more than

specified numbers.
