    EL6173
    3-Channel Laser Diode Driver w/Oscillator 
    & APC Amplifier
    The EL6173 is a high performance 
    three-channel laser driver that 
    provides controlled current to a 
    grounded laser diode. Write channels 2 and 3 can provide 
    up to 200mA per channel of DC or pulsed current, with 
    switching speeds of approximately one nanosecond rise/fall 
    time. All three channels are summed together at the I
    OUT
    output, allowing the user to create multilevel waveforms in 
    order to optimize laser diode performance. The level of the 
    output current is set by an analog voltage applied to an 
    external resistor which converts the voltage into a current at 
    the I
    IN
     pin (virtually ground). The current seen at this pin is 
    then amplified to become a current source at pin I
    OUT
    .
    An on-chip 500MHz oscillator is provided to allow output 
    current modulation when in any mode. This is turned on 
    when the OSCEN pin is held high. Complete control of 
    amplitude and frequency is set by two external resistors 
    connected to ground at pins R
    FREQ
     and R
    AMP
     (see graphs 
    in this data sheet for further explanation.)
    Output current pulses are enabled when an ‘L signal is 
    applied to the OUTEN pin. No output current flows when 
    OUTEN is ‘H’ and additional laser diode protection is 
    provided since the OUTEN input will float high when open. 
    Complete I
    OUT
     shut-off is also achieved by holding the 
    ENABLE pin low, which will override all other control pins.
    The EL6173 also includes a fast-settling APC amplifier 
    designed to interface directly with the front end monitor 
    diode and the sample-and-hold amplifier for read and write 
    power control. Its 100MHz bandwidth and 30ns settling time 
    enable up to 16X CD-RW design.

    NOTE: Intersil Pb-free products employ special Pb-free material 
    sets; molding compounds/die attach materials and 100% matte tin 
    plate termination finish, which is compatible with both SnPb and 
    Pb-free soldering operations. Intersil Pb-free products are MSL 
    classified at Pb-free peak reflow temperatures that meet or exceed 
    the Pb-free requirements of IPC/JEDEC J Std-020B.
