Technicolor - Thomson CDP-CX57 service manual Pin No, Pin Name, Function

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)
