AMCC delivers 10-Gbit/sec transceivers with electronic compensation
26 August 2003 San Diego, CA Lightwave - Applied Micro Circuits Corp. (AMCC) today announced the introduction of its third-generation S19235 and S19237 CMOS transceivers. These 10-Gbit/sec devices enable OEMs to deliver more integrated capabilities for line card and XFP module applications, while simultaneously driving down overall system power, cost, and size. The transceivers build upon AMCC's CMOS design capabilities and integrate the company's inter-symbol interference (ISI) electronic compensation technology. ISI technology extends the reach of lower-cost optics, thereby reducing overall costs for network carriers.
The S19235 and S19237 transceivers interface seamlessly with a variety of AMCC's OC-192 framers, mappers, and forward-error-correction (FEC) devices, and offer significant savings in power and real-estate. Both devices support OC-192/STM-64, 10 Gigabit Ethernet, 10 Gigabit Fibre Channel, and G.709 OTU-2 rates.
The S19235 and S19237 devices feature low jitter generation figures of 5mUI and 2mUI respectively, which exceed SONET jitter performance standards. Both transceivers offer exceptional performance for edge rates, signal integrity, and input sensitivity. The devices allow users to meet the maximum dispersion penalty per Telcordia GR-253-Core LR-2a, b, and c specifications with margin. Integrated into both devices on the receiver side is ISI compensation circuitry, offset cancellation circuitry to improve sensitivity, a limiting amp with threshold adjust, and clock/data recovery with phase adjust.
Ideal for implementation in an XFP environment, the transceivers feature a programmable TSD output differential swing, which affords power savings for module vendors. While the S19237 offers lower jitter generation and lower power dissipation than the S19235, the S19235 operates at an 11.3-GHz rate, enabling 10 Gigabit Ethernet and 10 Gigabit Fibre Channel traffic to be carried with FEC overhead.
Enabling customers to save on additional costs, the S19235 and S19237 feature an adaptive post-amplifier offset adjust to minimize offsets for low optical signal-to-noise ratio conditions, which eliminates the need for additional components. Packaged in a 255-pin plastic ball-grid array, the compact S19235 and S19237 integrate a built-in self test generator and checker capability, which allows customers to test part of their system during the design cycle, thus eliminating the need for test equipment, improving module quality, and driving down test costs.
The S19235 and S19237 are currently sampling to development partners, with general availability scheduled for Q4 2003. Volume pricing for the devices is $99.00 for the S19235 and $129.00 for the S19237.
