GENERAL DESCRIPTION  
The SP8107 is a three channel laser diode driver specifically designed for high speed DVD-RW or DVD-  
RAM applications. It operates two grounded laser diodes (650nm for DVD and 780nm for CD) and  
features three input channels that allow setting of three different optical power levels. The first channel  
(IR) has lower gain (100mA/mA) and output current (up to 200mA) and is used as a read channel. The  
second (I2) and third (I3) channels have higher gain (250mA/mA) and output current (up to 250mA) and  
are used as write channels. Each write channel may be switched on/off at very fast switching speeds with  
TTL/CMOS logic level signals applied to EN2 and EN3 inputs - channels are enabled at low logic level  
and disabled at high logic level. Outputs of all channels are summed together and connected to one of the  
outputs IOUT A or IOUT B depending on logic signal at the input SELA. High logic level at SELA selects  
output IOUT A, while low logic level selects output IOUT B. Inputs IR, I2, and I3 are current-controlled with  
200 ohm DC impedance but allow voltage control by using external limiting resistors.  
An on-chip oscillator is used to reduce laser mode hopping in read mode. The frequency of this oscillator  
may be changed by an external resistor connected to the RF pin. Oscillator swing can be set separately for  
I
OUT A and IOUT B outputs by two resistors connected to RSA and RSB pins respectively. The oscillator is  
enabled by high logic level at the OSCEN pin.  
Low logic level at the ENABLE pin disables the entire device. Supply current in disabled mode is below  
100uA. Pins EN2 and EN3 have internal pull-up resistors. Pins ENABLE, OSCEN, and SELA have  
internal pull-down resistors.
