T0810 General Description
The T0810 is a laser diode driver for the operation of a grounded laser diode for CD-RWdrives. It includes three channels for three different optical power levels which are controlled by a separate IC. The read channel generates a continuous output level whereas the channels 2 and 3 are provided as write channels with very fast switching speeds. Write current pulses are enabled when a 'low' signal is applied to the NE Pins. All channels are summed together at the IOUT Pin. Each channel can contribute up to 150 mA to the total output current of up to 200 mA. A total gain of 400 mA is provided between each reference current input and output. Although the reference inputs are current inputs, voltage control is possible by using external resistors.
An on-chipRF oscillator is provided to reduce lasermode hopping noise during read mode. Frequency and swing can be set by two external resistors.Oscillation is enabled by a 'high' at the ENOSC Pin. Complete output current and oscillator switch-off is achieved by a 'low' at the ENABLE input.
The T0810 also includes a fast settling APC (Adaptive Power Control) transimpedance amplifier. It is provided to interface between the front end monitor photo diode and the ALPC (Adaptive Laser Diode Power Controller) circuit.
