Freescale is an American company headquartered in Austin, Texas that designs and manufactures microcontrollers and semiconductors. Originally a native division of Motorola, it was divested in 2004 and is listed on the New York Stock Exchange. In 2012, its turnover was $4 Billion and it employed 16,500 staff. Their DSPs and baseband processors are embedded in macrocell basestation products by several major vendors.
In 2011, Freescale announced their Qoriq Qonverge PSC913x range - a series of Small Cell System-on-a-Chip devices with differing capacities:
- BSC9131 is a single core processor designed to handle up to 16 concurrent users in a single sector, targetted at enterprise femtocell applications
- BSC9132 is a dual core processor which can cope with up to 100 concurrent users in either 3G or LTE modes, or be configured to support both 3G and LTE simultaneously.
Both can be configured for TD-LTE or FDD-LTE modes, and include interfaces for Gigabit Ethernet, USB, RF and timing.
Freescale provide their own physical layer (PHY) and partner with several mainstream software vendors for the higher layers, including Radisys and Aricent. It interfaces directly with both MAXIM and ADI RF chipsets.
We interviewed Stephen Turnbull, Freescale's Marketing Manager for Wireless Access Products, for more details of their product launch and market fit.
In February 2012, ip.access selected the BSC9132 for their multi-mode LTE product development.
In March 2012, Public Wireless announced selection of the BSC9132 for its LTE small cell products.
In October 2013, ZTE announced selection of the BSC9132 for their TD-LTE small cell products.
