TZA1020A (AEGER2A) is an analog pre-processor IC for CD-R and CD-RW systems with 3-spots push-pull tracking system. The IC interfaces directly to the photo diodes.The device generates signals for laser power calibration and laser power control during disc writing. Normalized error signals are generated for servo control and wobble detection. An HF current amplifier is implemented to detect the actual HF data signal. The Fast Track Count (FTC) amplifier generates a radial error signal to allow fast track counting.
TZA1020A (AEGER2A) is similar to the TZA1020, except for non-clamped MIRN, which allows operation with IGUANA.
