Elantec Semiconductor heeft een nieuwe EL6281C laser driver ge´ntroduceerd waarmee lees- en schrijfsnelheden van meer dan 20X mogelijk worden. Het chippie is backwards compatible met de vorige generatie laser drivers van Elantec, waardoor fabrikanten van CD-RW drives hun producten met weinig moeite voor hogere snelheden geschikt kunnen maken:
Elantec Semiconductor, Inc. (Nasdaq:ELNT - news), a leader in high-performance analog ICs, today introduced a new high-speed laser driver in an ultra-thin package ideal for applications with height constraints such as those that exist for the emerging slim-line drive designs. The EL6281C is the third product of the next generation EL628XC family of laser drivers which will enable even higher read/write speed designs for products in the high growth CD-R/W optical disk drive market.
The EL6281C is a high-speed laser diode driver that provides the four current channels needed for the read, bias, erase, and write laser drive power levels. Built-in independent control of two frequency and two amplitude settings helps to reduce laser noise. The EL6281C also integrates the high frequency modulator (HFM) oscillator and the automatic power control (APC) amplifier for use with an external power monitor diode. This high level of integration saves cost by reducing component count and design time by reducing signal routing and space, thus enabling compact optical pick-up unit (OPU) design.
Steve Sacarisen, Director of Strategic Marketing, Optical Products Group, said, ``The EL6281C in the new ultra-thin LPP package, with frequency and amplitude control, faster rise and fall times, and backwards compatibility with previous generation laser drivers, helps our customers to rapidly move up the 'X' speed curve without costly redesigning.'' Mr. Sacarisen added, ``We believe the EL6281C can deliver read/write speeds beyond 20X, more than double the fastest speed available today!''
Pricing for the EL6281C is $2.50 in quantities of 10,000 units. Samples of the EL6281CU, in the QSOP24 package, and the EL6281CL, in the LPP24 ultra-slim package, are available immediately with production lead times of ten to 12 weeks.
