FunctionTerminal Name
Input/Output
49* PW Output Output terminal of subcodes P, A, R, S, T, U and W.
50* SFSY Output Output terminal of synchronous signal of subcode frame. It drops when subcode stands by.
51 SBCK Input Clock input terminal to read subcode. Schmit input (Connected to 0V when not used.)
52* FSX Output Output terminal of synchronous signal of 7.35kHz divided from quartz oscillation.
53 WRQ Output Output terminal to stand by output of subcode Q.
54 RWC Input Input terminal of read/write. Schmit input.
55 SQOUT Output Output terminal of subcode Q.
56 COIN Input Command input terminal from microcomputer.
57 CQCK Input Clock input terminal to fetch command input, or pick up subcode from SQOUT. Schmit input
58 RES Input Reset input terminal of LC78622. When turning on power, set it at "L".
59* TEST11 Output Output terminal for test. Used in the open state ("L" output as ordinary).
60* 16M Output Output terminal of 16.9344Hz.
61 4.2M Output Output terminal of 4.2336MHz.
62 TEST5 Input Input terminal for test Pull-down resistor is integrated. Surely connected to 0V.
63 CS Input Chip selection input terminal. Pull-down resistor is integrated.
Connected to 0when not controlled.
64 TEST1 Input Input terminal for test Pull-down resistor is integrated. Surely connected to 0V.
Pin No.
Note: The same potential must be supplied to the power terminals (VDD, VVDD, LVDD, RVDD, XVDD).
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
