Silicon Line aims at optical DisplayPort with ultra low power chipset

Launches World’s Most Power Efficient 6Gbit/s VCSEL Driver and TIA Chipset

By Nick Flaherty

Fabless analogue chip designer Silicon Line in Munich has launched an ultra-low power 6Gbit/s VCSEL (Vertical Cavity Surface Emitting Laser) driver and TIA (transimpedance amplifier) CMOS chipset that only consumes a total of less than 14 mW at full line rate, aiming at new applications such as optical DisplayPort links.
“In the consumer market we see several key trends. One trend is the demand for ever higher data bandwidth as Full HD video and 3D become mainstream in EMI sensitive devices. Another trend is the demand for dramatically reduced power consumption, not only to increase battery life for portable devices but also for environmental reasons. Additionally, devices with slim form factor designs are highly popular and they place severe restrictions on the size and mechanical flexibility of the link used to transport the high-speed data”, says Ian Jackson, Senior Manager Sales and Marketing at Silicon Line. “An optical link which uses these chips - the SL82028 and SL82018 - enables all these key trends”, he added.
An example of an application where these trends can be seen is the DisplayPort / embedded DisplayPort technology used in notebooks, netbooks and tablets, as well as to connect external monitors to PC’s. The latest version of DisplayPort, version 1.2, operates at 5.4Gbit/s per lane. When used in notebooks, netbooks or tablets, minimum power consumption is required in order to extend battery life. The inputs of SL82028 and the outputs of SL82018 are DisplayPort compliant and using an optical link using these ICs eliminates any EMI concerns and enables slim form factor designs.
The SL82028 and SL82018 are aimed at a wide range of applications including DisplayPort optical cables, mobile / smart phones, as well as other mobile consumer products like tablets, digital still cameras, digital video cameras, notebooks and netbooks. They can also be used for automotive, industrial and medical applications.
