SAA7818HL Datasheet | NXP Semiconductors

.. DVD and CD playback IC Rev. 03 - 25 November 2004 Product data sheet 1. General description The SAA7818HL is a device for 6 × DVD and 18 × CD playback applications. This device contains an embedded microcontroller which can operate as a 33 MHz or 67 MHz equivalent 80C51 and interfaces to the channel decoder, block decoder and servo processor. New Features enable superior playability in both CD and DVD modes. The block decoder has an embedded DVD video authentication module and supports up to 64 Mbit of external SDRAM memory. The data can be fed out in a number of different configurations including I2S-bus, ATAPI and UDE. This device also includes the option to bypass the external memory altogether, creating a bufferless ATAPI or UDE data path solution. The channel decoder has selectable differential and single-ended HF inputs, which are patible with the TZA1036 and TZA1038 devices. There is an option to output the data as raw I2S-bus via some programmable data I/O pins. With increased tap setting for the PLL equalizer pared with the SAA7816 device and enhanced playability of black dots and scratches, overall playability has been greatly improved. There are also benefits due to a new defect detector . that allows holding the HF PLL frequency and slicer settings over a defect. These, together with an additional limit equalizer lead to improved tolerance to continuity errors in DVD playback mode. There are also two extra motor gain settings pared to the SAA7816 device and support for copyright protection strategies in games applications. The servo processor has been upgraded to include an improved defect detection and handling process, an integrated envelope detection circuit and also DC offset pensation on the diode inputs.
