The T0800 is a laser diode driver for the operation of two different, grounded laser
diodes for DVD-RAM (650 nm) and CD-RW (780 nm). It includes five channels for five
different optical power levels which are controlled by a separate IC. The read channel
generates a continuous output level. The channels 2 to 5 are provided as write chan-
nels with very fast switching speeds. When a low signal is applied to the NE pins, write
current pulses are enabled. All channels are summed together and switched to one of
the two outputs IOUTA or IOUTB by the select input SELA. Each channel can contrib-
ute up to 200 mA to the total output current of up to 250 mA. A total gain of 100 is
provided between each reference current input and the selected output. Although the
reference inputs are current inputs, voltage control is possible by using external resis-
tors. An on-chip RF oscillator reduces laser mode hopping noise during read mode.
Frequency and swing can be set independently for the two selectable outputs with two
pairs of resistors. Oscillation is enabled by a high signal at the ENOSC pin. Complete
output current and oscillator switch-off is achieved by a low signal at the ENABLE
