Sipex Enters the High Definition DVD Market with State-of-the-Art Optical Signal Processing Components
SP8029 Completes the Sipex Chipset Required in Optical Pickups for HD DVD and Blu-ray Formats
MILPITAS, Calif., June 26 // -- Sipex Corporation today announced its state-of-the-art SP8029 Automatic Laser Power Control IC, which provides unmatched precision control and speed for laser diode power required by state-of-the-art High Density DVD (HD-DVD) or Blu-ray (BD) optical recorders and players. This precision and speed is necessary to extend operating life of the laser diode and guarantee an acceptable bit-error rate during "write-mode" operations.
A single SP8029 provides the power level control of all three laser wavelengths, 780nm, 650nm, and 405nm, used in CD, DVD, and both high density formats, HD-DVD and BD, respectively.
Key to the performance of the SP8029 is a fully-integrated photodetector with extremely low parasitics and excellent sensitivity, at all three wavelengths through a Sipex proprietary detector structure design. This embedded optoelectronic technology, in combination with a 20GHz BiCMOS process, results in a circuit with pulse response settling times of less than 5ns and bandwidths well in excess of 100MHz, critical to high speed writing operation.
The SP8029 enables the support of full length high definition movies for HD-DVD and Blue-ray when used in combination with a family of Sipex advanced optical signal processing circuits. The combined technology utilizes the 405nm wavelength blue laser diode to increase the recording density of an optical disk to 30 Gigabytes, sufficient capacity to accommodate more than 2-1/2 hours of high definition video.
The photodetector-based signal processing circuit, known as the PDIC, is located on the optical pickup head and consists of an array of up to twelve photodetectors which, in combination with >200MHz bandwidth amplifiers and buffers, are used to convert optical signals reflected from the disk to equivalent voltages representing digital data, disk tracking data and laser focus control data. Several previously released custom Sipex PDICs for Blu-ray and HD-DVD are in systems currently on the market.
The principal challenge of PDIC design is achieving wide signal bandwidth (>200MHz) at high gains while maintaining a high signal-to-noise ratio. The high signal-to-noise ratio enables the high data storage rates required for HD-DVD RW and Blue-Ray RW. Similar to the SP8029, Sipex utilizes a proprietary photodetector process and geometry which results in optical responsiveness of 0.23A/W at 405nm and 0.5A/W at 650nm and 780nm. This high responsiveness combined with high accuracy IC processing, results in a performance level unparalleled in the industry.
"With the release of the SP8029 we now have the best total performance optical chipset solution for our HD-DVD and Blu-ray customers," said Dr. Gi Young Lee, Optical Business Unit VP at Sipex. "These new circuits will be incorporated into a number of high definition recorders and players being introduced into the marketplace this fall for both consumer and computing applications."
Pricing and Availability
The SP8029 is available in a 16-pin, OLCC lead-free packaging compatible with JEDEC reflow cycle specifications for lead-free process. Pricing and technical information is available by contacting customersupport@sipex.com.
