4-2-1. Block Diagram (Wobble CLV Servo)

4-2-2. Wobble CLV Servo

CD-R : 16x CLV, 32x PCAV, 40x CAV, 48x CAV
CD-RW : 4x, 10x, 16x CLV, 24x, 32x ZCLV,
DVD-R : 2x, 4x CLV, 8x PCAV, 16x, 22x CAV
DVD-R DL : 4x CLV, 8x ZCLV
DVD-RW : 2x, 4x, 6x CLV
DVD+R : 2.4x CLV, 4x CLV, 8x PCAV, 16x, 22x CAV
DVD+R DL : 2.4x, 4x CLV, 8x ZCLV
DVD-RAM : 2x, 3x, 5x, 6x CLV, 6x-8x PCAV, x6-12x PCAV
DVD+RW : 2.4x, 4x, 6x CLV, 8x ZCLV

When drive write DVD-RAM/R/RW/+R/+RW/CD-R/CD-RW, the spindle motor is controlled using Wobble CLV
Spindle Servo.
The DSP Controller in MT1959H uses WOBSIG as linear velocity feed back, therefore the Wobble CLV
Spindle Servo doesn’t work well when WOBSIG signal is abnormal.
The spindle controller PWM output signal SPD (MT1959H 34pin) input to SPIN in Drive IC(TPIC2016G4 1pin)
after Low-Pass Filtering.
The PWM output signal U,V, W signal(TPIC2016G4 12, 13, 14pin) drives Spindle Motor without using a sensor.
