CIRCUIT DESCRIPTIONS A 1 Front End Part (MN35103UB, MN35104UB:IC1501) MN35103UB and MN35104UB are 1-chip LSI for DVD-Player. The connection of this LSI to the Driver IC, SDRAM, Flash-ROM, Audio-DAC, etc. can configure the DVD-Player System. This LSI contains Front End (SODC/FE) that performs RF signal /Servo /Decode processings, Back End (AV decoder/BE) that performs the video decode processing such as MPEG1/MPEG2/JPEG and audio decode processing such as DVD-Audio/AC-3/DTS/MP3, and the system controller (Siscon) for controlling the system. Front End part realizes the arithmetic processing of optical head signal and RF signal processing, the digital signal processing for DVD-ROM reproduction that conforms to DVD standards (16-8 Demodulation, Error correction), the digital signal processing for CD-DA/CD-ROM (Error correction), AV decoder transmission, servo control, spindle motor control and seek control. Please take note that, since (FEP) and (SODC) with DVD mecha-module (MS3) of CX-3016 are integrated into one chip at MN35103UB and MN35104UB, the waveforms of servo system on the front end which had B previously appeared at MS3, i.e., the waveforms of FE, TE and AS, cannot be seen anymore. 1.1 Analog Block (MN35103UB, MN35104UB:IC1501) The analog bl
