Description

The EL6835 is a high performance, dual output, laser driver for writeable 'super-combo'CD - 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 . The timing is determined by the signals at WEN2-WEN2B, WEN3-WEN3B, and WEN4-WEN4B. The oscillator is enabled when OSEN is high. The amplified IINR current of the selected channel is enabled when the ENA pin is high. The total output current is the sum of the read current, the enabled write currents, and the oscillator current when enabled.

Usually a voltage DAC will drive a resistor that is in series with the IINR , I IN2 , I IN3 , and I IN4  input. The resistor allows the user to optimize the current gain for each channel.

Output write current pulses EL6835 are enabled when a high is applied to the WEN2-WEN2B, WEN3-WEN3B, or WEN-WEN4B pin. The write current will flow to the selected output. When SEL1 is high IOUT1  is selected. WENRB enables read and oscillator current when low.


The EL6835 R oscillators frequency is determined by R FREQ1  or RFREQ2 , and its amplitude by RAMP1  or R AMP2
