Freescale Semiconductor launches a highly integrated base station-on-chip portfolio built on advanced heterogeneous multi-core technology. The QorIQ Qonverge series is the first scalable family of products sharing the same architecture to address multi-standard requirements spanning from small to large cells.

The QorIQ Qonverge portfolio of base station-on-chip products is based on a common architecture and integrates communications processing, DSP, and wireless acceleration technologies into a single SoC in various configurations for next-generation femtocell, picocell, metrocell and macrocell base stations, combining functions traditionally performed on separate FPGAs, ASICs, DSPs and processors to be incorporated on a single device.

This integration lowers part counts and delivers significant power, cost and footprint reductions for base stations. The common architecture spanning from femto cells to macro cells optimises R&D investments and software reuse.

The technology claims 4x cost reduction and 3x power reduction for LTE + WCDMA macro base stations, and 4x cost and power reductions for LTE + WCDMA pico base stations when compared to wireless infrastructure equipment powered by discrete silicon products.

QorIQ Qonverge processors combine multiple Power Architecture cores and high-performance StarCore DSPs with a MAPLE multi-mode base band accelerator, packet processing acceleration engines, interconnect fabric and next-node process technology. The portfolio's products support multiple standards, including GSM, LTE—FDD & TDD, LTE-Advanced, HSPA+, TD-SCDMA and WiMAX. In addition, the family's flexible architecture allows support for evolving standards with software upgrades.

The QorIQ Qonverge portfolio includes four distinct products optimised for small cell (femto and pico) and large cell (metro and macro) applications. It also supports remote radio head and emerging cloud-based radio access network (C-RAN) configurations.

The first products in Freescale's QorIQ Qonverge multi-core portfolio are built in 45nm process technology and planned for availability in 2H 2011. The products are the PSC9130/PSC9131 femto SoCs and PSC9132 picocell/enterprise femto SoC devices. Freescale plans to introduce portfolio members targeting larger cell (metro and macro) base stations built in 28nm process technology later this year.
