Atmel Extends its Laser Driver Family for Next-Generation DVD/CD Drives.Business Editors/High Tech Writers HEILBRONN, Germany--(BUSINESS WIRE)--Dec. 12, 2001 Atmel(R) Corporation (Nasdaq: ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) announced today the availability of 2 new members of its laser diode A semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but the laser diode generates a smaller beam that is easier to couple with the smaller core driver IC family for next-generation DVD/ CD drives. The 4-channel laser driver IC T0820 and the 3-channel laser driver IC T0816 are innovative, cost-effective solutions especially designed for high-speed DVD- and CD-R/RW (Read/ Read and Write) end products. Atmel's objective is to provide various solutions to meet the designers' different needs. Each of the new laser driver family members is dedicated to a specific application requirement. An earlier-introduced 3-channel laser diode driver IC T0815 is designed for high-speed CD-R/RW (Read/ Read and Write) end products where cost-effective design-in is an issue. The APC (1) (American Power Conversion Corporation, West Kingston, RI, www.apcc.com) The leading manufacturer of UPS systems and surge suppressors, founded in 1981 by Rodger Dowdell, Neil Rasmussen and Emanual Landsman, three electronic power engineers who had worked at MIT. (Adaptive Power Amplifier Power amplifier The final stage in multistage amplifiers, such as audio amplifiers and radio transmitters, designed to deliver appreciable power to the load. ) on the T0815 enables the direct connection of a front-end monitor diode, eliminating the use of an external operation amplifier and thus reducing system cost. The new 3-channel laser driver IC T0816 is functionally identical to the T0815 but has the APC function not on chip for those CD applications where the design requires that the APC is applied externally. The T0816 is Atmel's most cost-effective laser driver IC, its low complexity enables easy and quick design-in. The 4-channel laser driver IC T0820 also targets those applications where the APC function will not be on-chip. In contrast to the other laser drivers, however, the new T0820 is well suited for today's DVD-RW (DVD-Read Write) A rewritable (re-recordable) DVD disc for both movies and data from the DVD Forum. Also called "DVD Dash RW" and "DVD Minus RW," DVD-RW uses phase change recording. The media hold 4.7GB per side and can be rewritten 1,000 times. drives (4x to 8x re-write speed), currently being introduced on the market, and next-generation CD-RW (CD-ReWritable) The only rewritable CD technology. CD-RW disks look like other CD media, but with close inspection, they have a more polished surface with a very dark blue-gray cast. drives with 16x to 24x re-write speed. This laser driver supports the fastest write-time available today. Current-generation CD-R/RW drives available on the market provide a CD re-write speed of 10x, new products in production will reach a speed of 10x to 16x. To achieve increased speed, the used laser driver needs to provide high output current and a specific rise/ fall time. The T0820 includes four channels for different optical power levels. The first (read) channel and the second channel contribute up to 150 mA, the channels 3 and 4 up to 200 mA of the output current. Together, they deliver an output current of up to 300 mA. The T0820's rise/fall time of 1.0 ns meets the system engineers' requirements to enable new high-speed designs. An on-chip RF oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air reduces laser mode hopping noise during read mode. Frequency and swing can be set by two external resistors. Samples of the T0820 and the T0816 in SSO See single sign-on and CSO. SSO - single sign-on 16 packages are available now. Pricing starts at 2.50 US$ for the T0820 and at 2.10 US$ for the T0816 (both at 10 k).
