Milpitas, Calif. - Elantec Semiconductor Inc. is billing its EL-6287C laser diode driver as a lower-cost, better-performing replacement for its EL6257C.
The CMOS part, priced at $2.50 in quantities of 10,000, is said to enable makers of optical-disk drives to nearly double the read/write speeds of their products, from 10x to almost 20x. The part offers a 0.8-nanosecond tr/tf response time.
Otherwise, the chip is function- and pin-compatible with its predecessor. It integrates the four current channels needed for the read, erase, bias and write laser-drive power levels, and also integrates a high-frequency modulator oscillator with an automatic turn-off feature that's said to assure precise turn-off of the HFM during the write-channel enable.
The chip complies with the Orange Specification for CD-R and CD-R/W write-strategy formats. It's packaged in a 24-pin QSOP and is available eight to 10 weeks ARO.
