Infineon introduces the iLDD chip

Infineon Technologies today announced the first intelligent Laser Diode Driver (iLDD) targeting Small Form Factor (SFF) and Small Form Pluggable (SFP) optical transceiver applications.

Infineon Technologies today announced the first intelligent Laser Diode Driver (iLDD) targeting Small Form Factor (SFF) and Small Form Pluggable (SFP) optical transceiver applications for fibre based data storage and telecom systems.

The iLDD chip is said to integrate the Laser Diode Driver (LDD), the Post Amplifier (PA) and the Diagnostic Unit (DU). The digital Diagnostic Unit controls the performance of the entire optical module over the full data-rate range from 155Mbps up to 4.25Gbps and keeps track of laser safety regulations.

The iLDD chip also offers a high input sensitivity of 4mV and is able to drive the Vertical Cavity Surface Emitting Laser (VCSEL) as well as the edge-emitting laser. The device is fully MSA SFF-8472 compliant, operates from a single supply voltage with extended range from 2.85V to 3.63V and has a very low power consumption of 200mW. Volume production is planned to start in the fourth quarter of 2004.

“We are committed to provide the critical key technologies to optimise the increasing data traffic on Gigabit Ethernet, Fibre Channel and SONET/SDH fibre networks,” said Christian Scherp, Vice President and General Manger of Infineon’s North America Wireline Communications business group.

“The highly integrated iLDD is one of the most versatile solutions in the market enabling our customers to develop systems for fibre-based Backbone as well as Access Networks and reducing their overall costs,” added Scherp.

Infineon says the rapid growth of Internet-based applications such as e-mail, e-commerce, digital imaging or networked databases demands decentralised data storage centres (Storage Area Networks or SANs) for disaster resiliency and to meet legislative requirements with regards to data safety. Hence the increased storage transport and need for Fibre Channel (FC) interfaces that interconnect distributed SAN sites for enterprise customers.

According to market research firm iSuppli, the market for Gigabit Ethernet, Fibre Channel and SONET/SDH transceivers is expected to grow from $1.2 billion in 2003 to $3.9 billion in 2008 with a compound annual growth rate of approximately 26 per cent.
