Silicon Line GmbH introduces an ultra-low power
physical layer chipset for optical data transmission

Munich, Germany, January 22, 2008:
Silicon Line GmbH, a German fabless analog IC company, today
announced the release of a 2.5 Gigabit per second (Gb/s) chipset
comprising a transimpedance amplifier (TIA) with integrated limiting
amplifier and a Vertical Cavity Surface Emitting Laser (VCSEL) driver.
The complete chipset exhibits a total power dissipation of below 10
mW, only.
This power number includes all necessary currents through the
laser as well as the power dissipated by the resistive output load
connected to the TIA. The own power need of the VCSEL driver (SL82026)
itself is far
below 1 mW and that of the transimpedance amplifier (SL82016) far
below 5 mW.
“Optical data transmission based on polymer optical fibers or
waveguides becomes more and more prevalent.” said Holger Hoeltke,
Managing Director at Silicon Line. "Especially in mobile or portable
electronics, where massive EMI-constrains, bandwidth requirements and
mechanical issues challenge the traditional physical layer design,
ultra-low power optical data transmission comes in as perfect
alternative.
With its PHY-layer chipset Silicon Line provides an enabling
technology into these markets."
The chipset SL82016 / SL82026 features sub-LVDS I/Os, which provide a
differential output voltage of 200 mV.
Upon request, Silicon Line provides to its VCSEL-driver a temperature
controller, which automatically maintains over a wide temperature
range a given extinction ratio for the VCSEL.
Silicon Line's TIA, the SL82016, works together with either a GaAs
photodiode or a Si photodiode. With a minimum input current of 20 µApp,
the SL82016 allows for an optical input sensitivity of -16 dBm at
a BER of 10-12 at 2.5 Gbps.
"Due to their excellent power efficiency, both chips may also be used
for parallel optical links." said Martin Groepl, Silicon Line's
Technical Director. "With only a few adaptations we may provide them
as
one-dimensional or two-dimensional arrays. With that they're suitable
for high-speed board-to-board, backplane or chip-to-chip connections."
The SL82016 as well as the SL82026 exhibit a chip area of less than
0.5 mm˛. Both ICs are available in bare die form. Sampling of the ICs
starts now.
