TI develops chip set dor DVD-ROM and DVD players. The chip set contains all of the servo and stream decoding circuitry, but it requires and external MPEG-2 decoder. It should lower the cost of DVD-ROM solutions, thereby boosting sales of MPEG-2 decoders.....
TI's DVD Reference Design Incorporates Flexibility and Cost Effectiveness Through Programmable DSP
TUSTIN, Calif.--(BUSINESS WIRE)--Sept. 14, 1998--
Complete Development Environment for DVD Player and ROM Designs
Shortens Time-to-Market for Product Developers
The digital versatile disk (DVD) industry now has the most competitive and complete hardware reference design solution available from Texas Instruments Inc. (NYSE:TXN), the world leader in digital signal processor (DSP) and analog and mixed-signal solutions.
The DV25(TM) reference design is enhanced with a servo DSP based on the company's popular C2xLP DSP core, which allows for programmable flexibility. In addition, the new solution accelerates the development of low-cost consumer DVD-ROM and Players, and expands the use of DSPs in mass storage applications.
The DV25(TM) reference design is easily adaptable with a variety of loaders, pick-ups and MPEG decoders, and currently works with Sanyo's CD12FT DVD Player and CD22FT DVD-ROM loaders.
"The DV25(TM) chip set from Texas Instruments provides all the optical and servo processing necessary to control our latest CD12FT player and CD22FT ROM loaders," said Osami Sugito, planning manager for Sanyo Electric Co. Ltd.
"By combining Texas Instruments DSP leadership and mass storage expertise with our unique capabilities in DVD products, we are positioned to quickly bring-to-market Sanyo's premium loaders."
The new reference design is based on the company's successful DV25(TM) chip set, a complete, highly integrated, three-component solution providing signal acquisition and decoding as well as servo positioning and control of a DVD pickup and mechanism.
The reference design includes a complete, fully documented firmware solution for DVD servo and interface control, is adaptable to a variety of DVD pick-ups, directs parallel bus connections to external MPEG decoders, and has an ATAPI IDE interface for DVD-ROM application.
"Our new reference design allows DVD product engineers flexibility in supporting DVD Player and ROM designs with the same low-cost chip set. It also enables a whole new class of developers to implement DVD Player products with minimum design effort in a very short time," explained Jeff Harth, marketing manager for removable storage products at Texas Instruments Storage Products.
"The new chip set will have a significant impact on the wider acceptance of DVD technology, and lead to DVD Player solutions suitable for markets in the Far East based on both DVD-ROM and intelligent loader solutions. Most importantly, it will facilitate development of new, lower cost DVD Players for consumers around the rest of the world."
The heart of the new DVD reference design -- the DV25(TM) chip set -- consists of three highly integrated ICs, including:
-- the 33P3736 DVD/CD channel contains data recovery for a DVD
drive, direct serial port with internal registers for
configuring DVD and CD operation, programmable equalizer and
filter, data sum variable (DSV) asymmetry compensated data
slicer, RF attenuator and servo amplifier and demodulator that
increases adaptability with various pick-ups;
-- the 33H3825 servo DSP provides flexibility with various
loaders by implementing DVD and CD control of focus, sled
and radial actuator positioning, track counting, MCU interface
and constant linear velocity (CLV) or constant angular
velocity (CAV) spindle speed control; and
-- the 33C3925 DVD/CD data path controller provides all
functionality to read CD-ROM, CD-DA and DVD formats, including
eight-to-fourteen modulation (EFM), EFM+ and C1/C2 decoders, DVD error correction code (ECC) correctors, DRAM buffer
management, ATAPI interface and MPEG decoder port for external
audio/video decoder chip sets. Partitioning of the DV25 chip
set minimizes pin count and package complexity, thereby
reducing device interconnection and lowering overall system
cost. Players with performance to 4X DVD and 24X CD can be
implemented by using the chip set.
Samples are now available for the DV25(TM) chip set and production is scheduled for the last quarter of 1998. Pricing for the DV25(TM)chip set is planned to be at less than $15 each in 100,000 quantities.
