EL6839 Overview
PRELIMINARY Data Sheet July 15, 2004 FN7227.2 Dual 4-Channel Driver with Oscillator and LVDS The EL6839 is a high performance, dual output, laser driver for writeable DVD drives. The ENA pin enables the chip, while the SEL1 pin selects the IOUT pin. Various waveforms can be generated where the amplitude is determined by the currents flowing into IINR, IIN2, IIN3, and IIN4.
