Atmel Unveils World's Smallest FootPrint Photo Detector IC for DVD and CD Applications

Heilbronn, Germany (ots/PRNewswire)

Atmel(R) Corporation (Nasdaq: ATML) announced today the
availability of its new photo detector IC (PDIC) for use in the
optical pick-up units (OPUs) of DVD and CD drives. The new ATR0874 is
the industry's smallest PDIC device, measuring only 4 mm x 3.5 mm and
is a perfect fit for the slim drives found in most laptops. The new
ATR0874 is the first member of a new family of PDIC devices which
complements Atmel's current broad product range of Laser Diode
Drivers (LDD) and Automatic Power Controllers (APC).
The ATR0874 photo detector IC was developed using Atmel's in-house
BiCMOS process (with optical extension) and is manufactured in
Atmel's patented QFN open-housing technology. The QFN open-housing
has an open cavity thus permitting the laser direct access to the die
surface and therefore to the photo diodes. In addition, the housing
shares all the advantages of standard QFN housing including the
ability to be soldered at temperatures up to 260 degrees C which
reduces costs related to specialized soldering procedures. Competing
devices use clear molding, or glass lid packaging, which leads to
various problems such as scratches, voids, etc. These imperfections
may result in a higher bit error rate, reduced system performance and
a lower yield.
The new PDIC is designed for high-speed DVD applications such as
DVD-RAM and DVD+/-RW at a wavelength of 650 nm and CD-RW at a
wavelength of 780 nm. Due to the device's small footprint, it is
ideally suited for applications with highly-restricted space
specifications. The IC includes 10 channels with four different gain
steps and is optimized for fast settling times and low offset
Availability and Pricing
Samples of the new PDIC ATR0874 in 4 mm x 3.5 mm QFN open-house
packages are available now with pricing starting at US $1.00 for 10k
