Quellan Increases Copper Throughput to 6.25Gbps With EQ601 Settable Equalizer

Smart Gigahertz Technology Significantly Reduces System Interconnection Costs, Extends Wireless, Storage and Network Infrastructure Lifecycle

SANTA CLARA, Calif., April 4 /PRNewswire/ -- Quellan Incorporated, a developer of analog integrated circuits, today announced the EQ601 CMOS settable equalizer. Quellan's EQ601 Equalizer enables low cost copper system interconnections up to 6.25Gbps and effectively extends the useable length of copper cable in point to point communications applications.

Quellan's EQ601 is primarily used for card to card and shelf to shelf interconnections between the nodes in communication systems. By performing active signal conditioning due to high frequency transmission medium losses, Quellan's EQ601 extends signal reach and increases channel throughput.

The EQ601 provides unique features by using a combination of dynamic tuning and performance monitoring that allows engineers to address the widest range of trace boost settings and to easily determine the quality of the resultant eye pattern -- without expensive test equipment.

"The EQ601 allows vendors to future proof systems including wireless, storage and network infrastructure products with a tiny, low power single chip," said Tony Stelliga, Quellan's President and CEO. "The settable nature of the EQ601 allows it to improve performance on legacy and future systems, while the performance monitor provides a dynamic indication of signal quality -- under software control."

Quellan's EQ601 uses DC-coupled current-mode logic inputs/outputs and is available in a 4mm x 4mm 24-pin leadless LLP package. The EQ601 is fabricated in a .13 CMOS process and operates from a 1.2V supply over the -40 to +85 C temperature range and consumes only 90mW of power. Price is $7.65 (10,000--up, FOB USA).

"Pre-emphasis, equalization, and echo cancellation are the engineer's essential weapons for maintaining signal integrity in multi-Gigabit backplanes and interconnects. And while pre-emphasis and relatively simple equalization schemes have served us well at lower speeds, intelligent, non-linear equalization becomes an increasingly critical element of signal integrity as data rates pass the 5-Gbit/s threshold," said Lee Goldberg of analogZONE. "Above this threshold, we'll also see on-chip performance and signal, quality analysis capabilities becoming important tools for both set-up and real-time monitoring of multi-gigabit links."
