January 19, 2006 Tokyo, Japan -- TriAccess Technologies has introduced a FTTH radio frequency integrated circuit (RFIC) family designed to meet the high gain demands of Gigabit and Gigabit Ethernet passive optical network (GPON and GEPON) optical network unit/optical network terminal (ONU/ONT) video deployments.
According to a press release, the company has received its first design wins for its TAT6252 and TAT6254 series of RFICs; these products are scheduled to ship in pre-production volumes during the second quarter of 2006.
"These two new TriAccess RFICs enable system manufacturers to economically address the broad dynamic range requirements to support new GPON/GEPON high split ratios, and to provide a combination of analog and digital content through modern digital living room distribution networks," comments Chris Day, president and CTO of TriAccess Technologies. "The strong demand we are seeing for our TAT 625x series of RFICs suggests that these products uniquely meet the high gain and dynamic range requirements of FTTP GPON deployments."
With patent pending designs fabricated in 6-inch Gallium Arsenide pHEMT technology, key features of the devices, according to the company, include: greater than 30dB gain and 20dBmV/ch output; low equivalent input noise of 4pA/rtHz; low distortion of -70dBc even at high levels of optical input; configurability for a single 12-V supply to enable elimination of 5-V ONT supply voltage; a separate high output which easily drives a level detector used in RF automatic gain control implementations; and low differential input impedance to support a wide range of triplexers and 6-dB tilt for advanced RF/digital multimedia distribution.
The company says the devices round out a family of PON-optimized RFICs, each with unique strengths. According to the company, the TAT6252 is optimized for low power consumption (700 mW), ideal for system designers focusing on power draw, heat, and size; while the TAT6254 provides the flexibility to support a wide range of requirements, including DBS frequencies up to 2150 MHz.
"The breakthrough across all products is being able to reach new heights in gain while maintaining strong noise and distortion fundamentals," concludes Brian Bauer, vice president of marketing at TriAccess.
In 10K unit quantities, the TAT6252 is priced at $4.00 and the TAT6254 is priced at $4.50.
