TriQuint Semiconductor Inc. has introduced three new devices for CATV infrastructure and fiber to the premises (FTTP) applications, including the industry’s first amplifier supporting return path DOCSIS® 3.0 channel bonding with 5 to 300 MHz bandwidth. This capability can ensure long-term competitiveness and help ‘future proof’ incumbent cable TV systems.
Channel bonding is a broadband data transport solution for substantially increasing two-way data throughput in cable TV networks. This technology can aid cable operators in meeting customers’ current and future needs through economically scaled system upgrades. Existing silicon and previous GaAs-based solutions used for channel bonding do not match the bandwidth and output capability of TriQuint’s new solution.
TriQuint’s TAT3814 greatly simplifies return path system designs by integrating 36dB of gain and 20dB of automatic gain control (AGC) attenuation in a single 6x6mm surface-mount solution. It is ideally suited for cable modem, DOCSIS Set-top Gateway (DSG), set top box (STB) as well as optical node and new combined line extender/optical node applications. With it, cable operators can offer high-speed data capabilities competing with FTTP systems. High bandwidth helps support cloud-based access, video-calling, peer-to-peer access and other service expansions.
“TriQuint’s new return path amplifier demonstrates how we leverage our state-of-the-art technology. We base our solutions on customer needs. Not only does the TAT3814 help cable operators expand service offerings, it also sets the stage for future network upgrades. This is truly a device that helps them reach further and faster while gaining a competitive marketplace advantage,” said James L. Klein, TriQuint VP and GM for Infrastructure and Defense Products.
TriQuint’s new TAT3814 is production-released; it is sampling now along with other CATV/FTTP products introduced for the SCTE Cable-Tec Expo in Orlando, Florida, October 17-19. Contact TriQuint to arrange a meeting.
TriQuint has also introduced two new high performance 12V infrastructure power doublers: the TAT2801 and TAT8801A1H. Both are ideally suited for line extender output amplifier and distribution node amplifier designs. The TAT2801 provides exceptionally high output and linearity for DOCSIS 3.0 Edge QAM and cable modem termination system (CMTS) applications. It has the highest linearity of the two new doublers. The cost-effective TAT8801A1H is designed to meet most line extender output level requirements through its optimal performance and low power consumption.
The TAT6281 integrated video receiver introduced at the 2012 ANGA Cable Show began full production last quarter. The TAT6281 is part of TriQuint’s FTTH family, which includes the TAT6254 series. TriQuint’s FTTH solutions are deployed in 4 million residential and commercial locations worldwide. The TAT6281 utilizes the same topology as TriQuint’s highly-successful TAT6254 family, which includes PIN diode attenuation for consistent operation. It supports low-noise analog interface to optical triplexers in single family unit (SFU) FTTP applications.
