Freescale rolls out first products in QorIQ Qonverge wireless base station processor portfolio
August 31, 2011 // Phil Ling
The first 'base station-on-chip' products built on the QorIQ Qonverge multimode platform are now available. The PSC9132 and PSC9130/31 SoCs for femtocell base stations share a single, scalable architecture that simultaneously supports multiple air interfaces, providing operators and OEMs 'future-proof', highly integrated heterogeneous solutions that aim to help minimise power consumption, cost and design time.
The QorIQ Qonverge portfolio offers a scalable line of processors built on the same architecture that spans from small- to large-cell base stations, intended to allow OEMs to reuse software regardless of cell size.
This approach supports common hardware, software architecture and tools to minimise capital expenditure and benefit from a comprehensive solution that should help speed time to market. Freescale's first available QorIQ Qonverge processors are the PSC9130/31 femtocell SoCs (for eight to 16 simultaneous users) and PSC9132 picocell/enterprise SoC devices (for up to 100 simultaneous users).
The processors support a range of air interfaces, including LTE (FDD/TDD), WCDMA (HSPA+), WiMAX, UMTS and CDMA. The devices also incorporate glueless RFIC communication and antennae interfaces, eliminating the need for additional chips (such as FPGAs) and ultimately reducing board space and cost.
The ultra-integrated PSC913x family also provides support for GPS synchronisation and 2G/3G sniffing in a single device. The SoCs are built on Power Architecture cores, programmable StarCore digital signal processor (DSP) technology and powerful baseband hardware acceleration engines already deployed in multiple LTE macrocell base stations around the world, the QorIQ Qonverge processors bring together Freescale's signature intelligent integration capabilities.
Using StarCore SC3850 DSP and Power Architecture e500 MPU cores, the QorIQ Qonverge SoCs are distinguished by offloading Layer 2 processing and above to MPU cores instead of DSP cores, delivering significant efficiency advantages.
