IDTâs Patent-protected Compression IP Reduces System Cost by Enabling the Use of Low Cost Fiber to Connect RRUs to Baseband Unit in Wireless Infrastructure
SAN JOSE, Calif., February 21, 2012 â Integrated Device Technology, Inc. (IDTÂ®) (NASDAQ: IDTI), the Analog and Digital Companyâ¢ delivering essential mixed-signal semiconductor solutions, today announced data compression intellectual property (IP) that offers the industryâs highest performance in 3G and 4G wireless infrastructure applications. IDTâs patent-protected baseband data compression IP reduces system cost by enabling the use of low cost fiber optic cabling to connect the remote radio unit (RRU) to the baseband unit (BBU).
In an industry where performance and cost demands pull strongly in opposite directions, wireless communication equipment manufacturers are looking for solutions to pass increasing amounts of data over inexpensive, low-speed fiber optic cable links (up to 2.5 Gbps). IDTâs data compression IP solves this dilemma by offering compression ratios from 2:1 to 4:1, enabling customers to utilize low-cost cabling by reliably compressing data while keeping overall signal quality within required wireless parameters. IDTâs compression IP is the only IP in the industry achieving 3:1 compression at the error vector magnitude (EVM) percentage required in 4G systems at full Common Public Radio Interface (CPRI) line rates. The data compression IP is available as an FPGA or ASIC instantiation suitable to support GSM, WCDMA, and LTE systems.
âOur industry-leading compression IP offers our customers the tools and support they need to develop high-performance and cost-effective wireless communication solutions,â said Tom Sparkman, vice president and general manager of the Communications Division at IDT. âWith 4G-compliant EVM rates at a 3:1 compression ratio, the value proposition of IDTâs compression IP is highly attractive to all BBU manufacturers looking for a competitive advantage. Coupled with our Serial RapidIO interconnect, RF signal path, timing, and high speed data converter products, IDT offers the industryâs most complete and compelling wireless signal chain solutions on the market.â
IDTâs compression IP operates with sub-microsecond latency for the entire compression and decompression chain, having negligible impact on overall system performance. Furthermore, while the compression IP is typically used to compress data on the link between the RRU and BBU in radio access networks, it can also be used to compress data in repeater systems on the link between master and slave units. This provides customers the opportunity to use fewer fiber links and optical connectors to save considerable cost and power.
