General Description
The MAX9483/MAX9484 high-performance, multimode,
laser-diode drivers (LDDs) are designed for CD and
DVD combination pickup heads. The drivers consist of
three input channels, an RF oscillator, and two preci-
sion current-amplifier outputs to drive the CD and DVD
laser diodes. The MAX9483/MAX9484 support multiple
CD and DVD read/write standards, such as CD-R/RW,
DVD-R, DVD+R, DVD-RW, DVD+RW, and DVD-RAM by
choosing the writing control signals and input currents
on these input channels. The peak total output current
is 400mA with a current gain of 100 at each channel.
External resistors set the oscillation frequency and out-
put swing. The MAX9484 features an extra resistor
input allowing the oscillation frequencies of the two out-
puts to be set separately. Additionally, the MAX9484
allows the writing control signals to be received in low-
voltage differential signal (LVDS) mode or single-ended
mode to provide reliable high-speed writing.
The MAX9483 is offered in 16-pin QSOP and 4mm x 4mm
16-pin thin QFN packages. The MAX9484 is offered in a
4mm x 4mm 20-pin thin QFN package. Both devices are
specified for 4.5V to 5.5V supply and 0°C to +70°C tem-
perature range.
