JTAG boundary-scan test solutions for femtocells

EINDHOVEN, THE NETHERLANDS: Swindon, UK-based femtocell vendor Ubiquisys is using JTAG Technologies’ boundary-scan test solutions for volume production of its ZoneGate product.

The provision of the test solutions is the result of extensive collaboration between the two companies and, by providing test development services and systems for factory testing, JTAG Technologies was able to relieve the burden of developing structural PCB tests.

Femtocell products address the urgent demand from consumers for cost-effective, high-quality 3G coverage in the home, and Ubiquisys’ offering introduces a fast and efficient way of opening the Internet to mobile users and delivering new revenue streams to operators.

ZoneGate, which is in mass production today at Sony UK Tech, is a single PCB product which architecturally splits into RF circuitry, baseband processing, clock circuits and power supplies. The baseband processing is achieved using a custom femtocell chip and an FPGA, memory is provided by DDR2 SDRAM and there is also a flash chip.

Pete Keevill, founder and VP Engineering of Ubiquisys, comments: “ZoneGate is a relatively compact, mixed-signal design

with about 1,000 nets, the majority of which connect BGA-packaged digital components.”
