CATV HFC and Broadband Telecom Networks Power Supplies

 

A full range of custom and semi-custom headend and network equipment and devices designed for broadcast, broadband, and CATV systems. Products include video encoders and decoders, fiber optic transmitters and network nodes, laser drivers, routers and switchers, multiplexors, VOD servers and video ingestion devices, cable modem termination systems (CMTS), Virtual Converged Cable Access Platforms (CCAP), network amplifiers and repeaters, management and control systems, and more.

For Hybrid Fiber Coaxial (HFC) networks, the power supplies support the CATV quasi-square wave sine input and universal AC input. Each product features a fully synchronous rectifier design and employs two-phase PFC, DC/DC conversion, and digital load sharing. Products also include digital signal processing (DSP), which uses the industry standard SMBus to provide real-time monitoring and control of system performance, including timing, digital control loops, and multiphase clocking. Communication interfaces include I2C, SPI, RS232, and RS485.

Enclosed and open frame power switching solutions to power optical fiber nodes in HFC networks and HUBs. These products provide very high efficiency, high power density, and multiple power and voltage options. The AC input power supply shares CATV RF signals to minimize conducted emissions in the CATV upstream or downstream bandwidth from 5 MHz to 1,218 MHz, according to ANSI/SCTE 82 test method.
