9 / 34 page No. 5342-9/34 LC78631E Note: Of the general-purpose I/O ports, any unused input ports must be connected to 0 V, or set to be output ports. Pin No. Symbol I/O Function 51 XVSS Crystal oscillator ground. Must be connected to 0 V. 52 XOUT O 16.9344 MHz crystal oscillator connections. Use a 33.8688 MHz crystal oscillator for quad-speed playback. 53 XIN I 54 XVDD Crystal oscillator power supply 55 RVSS Right channel ground. Must be connected to 0 V. 56 RCHN O One-bit D/A Right channel N output 57 RCHP O converter pins Right channel P output 58 RVDD Right channel power supply 59 MUTER O Right channel mute output 60 SBSY O Subcode block synchronization signal output 61 EFLG O C1 and C2 error correction state monitor 62 PW O Subcode P, Q, R, S, T, U, V, and W output 63 SFSY O Subcode frame synchronization signal output. Falls when the subcode output goes to the standby state. 64 SBCK I Subcode readout clock input. This is a Schmitt input. This pin must be connected to 0 V if unused. 65 DOUT O Digital output 66 FSX O Outputs a 7.35 kHz synchronization signal generated by dividing the crystal oscillator frequency. 67 WRQ O Subcode Q output standby output 68 RWC I Read/write control input 69 SQOUT O Subcode Q output 70 COIN I Input for commands from the control microprocessor 71 CQCK I Command input acquisition clock. Also used as the SQOUT subcode readout clock input. This is a Schmitt input. 72 RES I Chip reset input. This pin must be set low temporarily when power is first applied. 73 FAST O Functions as the PCK frequency detection monitor output in VCEC mode. 74 CONT2 O Output port 75 16M O 16.9344 MHz output. 33.8688 MHz output in 4 × playback mode 76 4.2M O 4.2336 MHz output 77 TEST5 I Test input. A pull-down resistor is built in. Must be connected to 0 V. 78 CS I Chip select input. A pull-down resistor is built in. When control is not used, this pin must be connected to 0 V. 79 DEFI I Defect detection signal input. Must be connected to 0 V if unused. 80 VCOC I Variable pitch VCO control input. Must be connected to 0 V if unused. Continued from preceding page. |
