Picocell, femtocell SoCs sampling
1 min read
Following the announcement of the Qonverge range at Mobile World Congress earlier in 2011, Freescale has announced that it is now sampling the PSC9130/31 and PSC9132 SoCs, aimed at femtocell and picocell applications respectively.
The PSC9130/31 femtocell SoCs support eight to 16 simultaneous users, while the PSC9132 will handle up to 64 simultaneous users.
Stephen Turnbull, portfolio manager for Freescale's high performance embedded processor range, said: "We will be offering a range of products. Alongside these three devices, there will be more parts addressing different price/performance points, but featuring a common architecture."
Each part features the StarCore SC3850 dsp, as well as the Power Architecture e500 mpu core. While the 9130/31 have one of each, the 9132 boasts two dsp cores and dual e500s. However, all parts can offloading Layer 2 processing and above to the mpu cores, delivering 'significant efficiency advantages'.
A range of air interfaces is supported, including LTE, WCDMA, WiMAX UMTS and CDMA. The devices also incorporate RFIC communication and antennae interfaces, eliminating the need for additional chips. Turnbull noted: "Integration is key for this area, where developers are looking to reduce the bill of materials, as well as power and cost."
