Smathers brings analogue industry experience

Quellan has developed a complete family of chips for providing high speed interconnections between data centre systems. Quellan's Lane Managers deliver interconnect at datarates of up to 6.25Gbit/s over copper cabling or system chassis. The company demonstrated its QLM4503 Lane Manager achieving 5Gbit/s throughput on a 1.25Gbit/s system chassis this week at the annual DesignCon Conference.
This 300% performance improvement was made possible with Quellan's CSP collaborative signal processing architecture that provides adaptive noise cancellation and efficient equalisation to the channel.
Quellan's Lane Managers also manage channel power, impedance, link integrity and provide performance monitoring - essentially an analogue measure of the signal quality on a real time basis.
These capabilities form Quellan's 'signal integrity firewall' for system designers, particularly in the burgeoning blade server marketplace where multiple vendor blades must interoperate at the signal and link layer.

The company's Lane Manager products are targeted at numerous serial interconnect applications including PCI Express, Fibre Channel, Infiniband, SAS, CX4 and OIF CEI.
'The full feature set, multistandard support and high integration of our Lane Managers bring PC economics to data centre interconnects', said Tony Stelliga, Quellan's President and CEO.
'Increasing density and cost pressures in the data centre present a major signal integrity challenge for system engineers'.
'Quellan's Lane Manager products overcome this challenge with a signal integrity firewall that delivers the highest channel throughput and reach over inexpensive media'.
Pricing starts at under $2 per port and operating speeds range from 2.5 to 6.25Gbit/s.
Optional features include single or quad port density, performance monitoring and crosstalk cancellation.
Package sizes range from 3 x 3 to 12 x 12mm depending on port density and functionality.
The QLM4602 is a quad lane manager packaged in a 7 x 4mm 46-pin QFN package and operates from a 1.2V supply over the 0 to +85C temperature range, consuming only 60mW of power per active channel.
Prices start at $7.95 (10,000 units).
