GENERAL DESCRIPTION 1.1 ZR36768 The ZR36768 Disc Loader Controller and Decoder Device can control disc loaders and read bitstreams using the following media: DVD-ROM, DVDRW, CD-DA, CD-ROM, CD-R and CD-R/W discs. The device can decode bitstreams and process navigation data of the following formats: DVD-Video, DVD-Audio, CD-DA, VCD (Video-CD), SVCD (Super Video-CD) and MP3. The features of this chip can be listed as follows: Disc loader control and bitstream processing 8 analog inputs (low frequency) for servo errors and RF signals envelope monitoring 11 actuators drive or control outputs. Two analog outputs through 11 bits DACs (e.g. for the tracking and focus coils), and 9 PWM outputs divided into two type groups: High frequency, “uniform” type PWMs (e.g. for the spindle and sled motor drives), and lower frequency “regular” type PWMs, which can be used e.g. for programmed tray motion or RF amplifier parameter setting. Processing of spindle and sled position read-back devices All servo loop closure, closed loop control and error handling. Bitstream extraction using AGC, bit clock frequency detection and phase lock loop, adaptive threshold calculations, Viterbi bit decision, defect detection, frame sync detection and EFM/P conversion.

The maximum amount of memory supported is 8 MB of Synchronous DRAM (SDRAM). The memory interface is configurable in depth to support 64-Mb addressing. 1.3 DRIVE INTERFACES The ZR36768 supports direct interface (through RF and servo amplifiers) to several types of disc loaders. 1.4 FRONT PANEL The front panel is based around a Futaba VFD and a Princeton front panel controller chip, (PT6311). The ZR36768 controls the PT16311 using several control signals, (clock, data, chip select). The infrared remote control signal is passed directly to the ZR36768 for decoding.
