EL6298 ® Data Sheet July 15, 2004 Laser Diode Driver with Waveform Generator Features The EL6298 is a highly integrated laser diode driver designed to support multi-standard writable optical drives. It accomplishes this by incorporating a waveform generator wherein the diode currents and timing details can be programmed before operation. The data input circuitry inspects the NRZ serial data waveform and generates programmed waveforms in recognition of 3, 4, 5, or 6 or more clock periods of space changing to 3, 4, 5, or 6 or more clock periods of mark, and vice versa. NRZ and clock are LVDS. • Complete programmable laser diode driver This programmable architecture allows reprogramming of the timers to support different media, DVD or CD standards, and different speeds. The programming is accomplished through a serial interface port. Two outputs are provided to support dual-laser multi-standard optical heads. The EL6298 requires 3.3V and 5V supplies, with all the logical interface operating on the 3.3V supply. The EL6298 is available in 32-pin QFN and 32-pin QFN packages for improved thermal performance and reduced footprint. • 4MHz - 200MHz clock • 250mA maximum write output • 8-bit x 8-bit multiplying DAC output provides 8-bit full scale adjustment and 8-bit resolution at any full scale output • 0.12ns timer resolution • Two laser outputs allows read/write DVD and CD combinations • Programmable waveform values support 2.6GB DVDRAM, 4.7GB DVD-RAM, DVD-R, DVD+RW, DVD-RW, CD-RW, and CD-R • Analog input supports APC • HFM oscillator programmable to 100mAP-P from 200MHz to 600MHz • PLL allows reduced-frequency clock on flex cable • Separate serial input works up to 25Mb/sec • Pb-free available Applications • Combination DVD writable and CD writable drives • DVD camcorders Ordering Information PART NUMBER FN7274 • DVD video recorders PACKAGE TAPE & REEL PKG.
