12D-NE20/NE20LSSECTION 5DIAGRAMSNote on Printed Wiring Boards.• X : parts extracted from the component side.• Y : parts extracted from the conductor side.• : Pattern from the side which enables seeing.(The other layers' patterns are not indicated.)NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.Caution:Pattern face side: Parts on the pattern face side seen from(Side B) the pattern face are indicated.Parts face side: Parts on the parts face side seen from(Side A) the parts face are indicated.• These boards are multi-layer printed board. However, the paternsof intermediate-layer have not been included in the diagram.• Waveforms– EGH Board –540 mVp-p1 TP608 (RF)3.0 Vp-p2 IC603 EXTAL44.1 ns200 mV/DIV, 400 ns/DIV1 V/DIV, 20 ns/DIVNote on Schematic Diagrams.• All capacitors are in μF unless otherwise noted. (p: pF) 50 WV orless are not indicated except for electrolytics and tantalums.• All resistors are in Ω and 1/ 4 W or less unless otherwise specified.• f : internal tolerance.• C : panel designation.• A : B+ Line.• Total current is measured with CD installed.• Power voltage is dc 1.5 V and fed with regulated dc power supplyfrom battery terminals.• Voltages and waveforms are dc with respect to ground in playbackmode.no mark : CD PLAY∗ : Impossible to measure• Voltages are taken with a VOM (Input impedance 10 MΩ).Voltage variations may be noted due to normal production toler-ances.• Waveforms are taken with a oscilloscope.Voltage variations may be noted due to normal production toler-ances.• Circled numbers refer to waveforms.• Signal path.J : CDc : DIGITAL OUT• AbbreviationCH : Chinese modelEE : East European modelJE : Tourist modelKR : Korean modelNote: The components identified by mark 0 or dottedline with mark 0 are critical for safety.Replace only with part number specified.www. xiaoyu163. comQQ 376315150 992894298TEL 13942296513 992894298051513673QQTEL 13942296513 QQ 376315150 892498299TEL 13942296513 QQ 376315150 892498299http://www.xiaoyu163.comhttp://www.xiaoyu163.com |
