Atmel Extends Its LVDS Laser Diode Driver Family with Industry's First IC Enabling 8x DVD Dual-layer Write Speed

Heilbronn, Germany (ots/PRNewswire)

- New Laser Diode Driver is the Only One Available in a 4x4 mm
Green QFN24 Package
Atmel(R) Corporation (Nasdaq: ATML), a global leader in the
development and fabrication of advanced semiconductor solutions,
announced today the availability of two new laser diode drivers for
8x DVD dual-layer write speed. The new devices extend Atmel's
existing family of laser diode drivers with Low Voltage Differential
Signals (LVDS) for enhanced write speed.
The ATR0839 and ATR0849 support DVD+/-RW/CD-RW combo drives with
up to 16x writing speed for DVD+/-RW and 52x for CD-RW. Due to their
maximum output current of more than 700 mA, they also support a write
speed of 8x for the new dual-layer DVD+/-RWs. Since these new devices
are provided in very small packages, they are particularly suited for
small SLIM drives in notebooks, as well for half-height drives used
in desktop PCs and consumer DVD recorders.
The two new devices provide four-channels, one read channel and
three write. The write channels are controlled by LVDS signals. Since
the LVDS termination is on-chip, system designers can save three
resistors in their bill of materials, which helps reduce space and
cost. The two outputs can be used either for DVD laser diodes with a
wavelength of 650 nm or for CD laser diodes with a wavelength of 780
nm.
An integrated oscillator reduces laser mode hopping during read
mode. With four resistors, the oscillator's frequency and swing can
be set for each output separately. The ATR0839 enables the oscillator
by LVDS signals. The ATR0849 performs this function by
CMOS-compatible single-ended signals.
Samples of the ATR0839 and ATR0849 are available now in very small
QFN24 packages, which are both Pb-free and green. Atmel is the only
supplier offering such a product in a package measuring only 4 mm x 4
mm x 0.9 mm. Both devices will also be available soon in
pin-compatible QFN packages with the exposed pad on top. Pricing for
each of the devices starts at 2.60 US$ in quantities of 10 k.
