Integrated Device Technology (IDT) has unveiled data compression intellectual property (IP) that is claimed to offer the industry’s highest performance in 3G and 4G wireless infrastructure applications. The patent-protected baseband data compression IP reduces system costs by enabling the use of low cost fiber optic cabling to connect the remote radio unit (RRU) to the baseband unit (BBU).
Performance and cost demands pull strongly in opposite directions in this industry, as a result 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). IDT’s data compression IP looks to solve 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. IDT’s compression IP is said to be the only IP in the industry that is able to achieve 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.
“Our compression IP offers our customers the tools and support they need to develop high-performance and cost-effective wireless communication solutions,” said Tom Sparkman, vice president and general manager of the Communications Division at IDT. “With 4G-compliant EVM rates at a 3:1 compression ratio, the value proposition of IDT’s 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 industry’s most complete and compelling wireless signal chain solutions on the market.”
IDT’s 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.
