Pre-processing switch for 3G base stations
3 October 2007
Telecoms, Datacoms, Wireless, IoT
IDT has released its second generation pre-processing switch, the PPS Gen 2, an innovative, off-the-shelf solution that addresses the interconnect and acceleration needs of 3G and beyond. Leveraging the serial RapidIO (sRIO) interconnect standard, the PPS Gen 2 is optimised for the support of small DSP clusters that are commonly used in micro and pico base stations. The PPS Gen 2 distributes data to multiple DSPs to increase performance, supporting four pre-processing blocks via three 4x ports or up to 12 1x ports, with flexibility to connect among 4x and 1x ports. Each port can be configured for 3,125 Gbps, 2,5 Gbps or 1,25 Gbps. All IDT PPS solutions implement standard sRIO switching operations, with the additional ability to execute critical endpoint tasks, such as byte- and packet-level data manipulations, and other mathematical and memory management operations.
