Silicon Line introduces SL82728, SL82718 ICs

Supports up to four data lanes at up to 6 Gbps per lane

By CBR Staff Writer

Ultra-low power analog ICs provider Silicon Line has introduced the SL82728 and SL82718 ICs targeted at notebooks, ultrabooks and tablets using the latest VESA based Embedded DisplayPort standard.

SL82728 and SL82718 ICs are used to optically connect the graphics processor to the display and enable the replacement of traditional electrical connectors with optical connectors and enable the company to support the latest trends for high performance displays in notebooks, ultrabooks and tablets.

The optical Embedded DisplayPort ICs support up to four data lanes at up to 6 Gbps per lane and therefore they can be used to implement the Embedded DisplayPort Version 1.3 standard which specifies a maximum of 5.4 Gbps per data lane.

In addition, the ultra-low power consumption, which is less than 13 mW per channel at 6 Gbps, makes the new IC’s ideal for mobile battery operated consumer devices such as notebooks, ultrabooks and tablets.

The SL82728 quad channel vertical cavity surface emitting laser (VCSEL) driver and the SL82718 quad channel transimpedance amplifier (TIA) together with appropriate photonics are used to implement an optical link for transporting high speed Embedded DisplayPort signals from the graphics processor to the display.

Silicon Line Sales and Marketing senior manager Ian Jackson said the latest generation of retina type displays demand extremely high data rate.

"As an example, a 10 inch tablet display with 500 pixels per inch can require up to 23 Gbps and when used in 3D mode would require twice that bandwidth. Optical transport of these signals solves the EMI challenges which these data rates create as well as enabling the small and thin form factor designs specified for Ultrabooks", Jackson said.
