Milpitas, Calif. Magnum Semiconductor has launched the MS3900 front-end processor for DVD recorders and players. The DSP-based IC provides optical disk data and servo processing on a single chip to perform DVD encoding, DVD and CD decoding, and servo control functions.
Housed in a 208-pin LQFP package which measures 28 x 28 mm, the MS3900 includes on-chip analog-to-digital (A/D) and digital-to-analog (D/A) converters. The architecture uses a proprietary DSP and built-in RAM for servo control programming to enhance the flexibility of the servo control function.
During read operations, the on-chip digital phase-locked loop (PLL) provides high data-recovery rates with EFM and EFM+ demodulation. During write operations, the on-chip delay-locked loop (DLL) provides write-strategy while the PLL provides write clock generation.
The MS3900 provides a full ATAPI interface, as well as a direct host bus interface for popular multimedia back-end processors such as Magnum's MS9400 family. The direct host bus interface allows the front-end and back-end tasks to be integrated into mono-board systems which reduce product costs by eliminating the separate optical drive controller board with its CPU and memory.
The MS3900 works with optical pick-up units from multiple vendors including Hitachi and Samsung. In addition, the MS3900 provides CSS and CPRM keys for digital rights management.
Pricing: Less than $10 in OEM quantities.
Availability: The MS3900 is in production and is available now.
