Pin No. Pin Name I/O Function
42 MUTER O Line muting on/off control signal output terminal (for R-ch side) “H”: muting on
43 XVDD — Power supply terminal (+5V) (crystal oscillator system)
44 XOUT O System clock output terminal (16.9344 MHz)
45 XIN I System clock input terminal (16.9344 MHz)
46 XVSS — Ground terminal (crystal oscillator system)
47 SBSY O C1, C2, single correction, and double correction monitor output to the CD text decoder (IC104)
48 EFLG O Subcode P to W output terminal
49 PW O Subcode frame sync signal output to the CD text decoder (IC104)
50 SFSY O Write frame clock signal output to the CD text decoder (IC104)
51 SBCK I Subcode reading clock signal input from the CD text decoder (IC104) (schmitt input)
52 FSX O 7.35 kHz sync signal output divided from the crystal oscillation
53 WRQ O Subcode Q synchronizing signal output to the system controller (IC501)
54 RWC I Command chip enable signal input from the system controller (IC501) (schmitt input)
55 SQOUT O Subcode Q data output to the system controller (IC501)
56 COIN I Command serial data input from the system controller (IC501)
57 CQCK I
Command serial clock signal input from the system controller (IC501) (schmitt input)
Fetching clock input or subcode extracting clock input from SQOUT (pin %
∞ )
58 RES I
System reset signal input from the reset signal generator (IC201) “L”: reset
For several hundreds msec. after the power supply rises, “L” is input, then it changes to “H”
59 TEST11 O Test output terminal Not used (open)
60 16M O Master clock signal (16.9344 MHz) output to the CD text decoder (IC104)
61 4.2M O Reference clock signal (4.2336 MHz) output to the RF amplifier (IC102)
62 TEST5 I Test input terminal (fixed at “L” in this set)
63 CS I Chip select signal input terminal Not used (fixed at “L”)
64 TEST1 I Test input terminal (fixed at “L” in this set)
