Terawave and K-micro combine on high-performance GPON PHY

"Terawave BM-CDR technology enables full compliance with GPON ITU-T G.984.x Recommendations for burst-mode operation" said Boris Auerbuch, VP Engineering and CTO of Terawave Communications. "The New ASIC supports extended temperature range and can be used for both indoor and outdoor applications."

K-micro has integrated its burst mode clock and data recovery (BM-CDR) technology into this new ASIC. It has appeared in two previous generations: the first-generation "Copper Tub" (CT1) that runs at 1244/1244, and a later CT2 that runs at 2488/1244.

The device supports arbitrarily long bursts without loss of lock, and incorporates a variety of advanced features to support functions such as optoelectronics control and synchronization, chatter suppression, and auto-discovery. Implementation of this functionality in a pure CMOS process minimizes power dissipation and device cost.

The Terawave TW-800 Family of OLTs are first to incorporate this technology. The TW-801 OLT is one of a series of OLT packages designed to address the emerging GPON global market. These products are completely G.984.x ITU standards compliant.

"The partnership of Terawave and K-micro has enabled the development of the highest performing single chip PHY in the industry, combining the GPON knowledge and engineering capability of Terawave with K-micro's high performance SERDES and burst mode CDR has resulted in creating this advanced device" said Vijay Pathak CTO of K-micro.

The Terawave TW-800 OLT family is available now for customer lab trials and will be generally available in Q1 2007. Terawave is a supplier of GPON technology to Fujitsu for the BT21C network.
