Fairchild Semiconductor has an innovative new line of ultracompact serialiser/deserialisers called uSerDes (micro-serdes), offering the industry's most compact, lowest EMI and lowest power solution for high speed data serialisation within ultraportable applications. The new Fairchild FIN12 and FIN24 series devices are ideal for solving the increasingly complex design challenges posed reliable data transmission, in particular through the hinge or rotation axis to the display in clamshell designs. These uSerDes devices reduce traditionally wide parallel paths of data to a high-speed serial link, reducing the interconnection to six to seven times fewer wires.
The serial link is implemented using innovative EMI-reducing differential technology that can result in faster electromagnetic compatibility (EMC) regulatory system approval.
This highly flexible interface solution can easily be implemented across multiple display platforms allowing for a shortened product development cycle and speeding time to market.
uSerDes also lowers overall component count and board-space requirements, helping to optimise the sise and cost efficiency of cellphones, digital cameras, printers and other space-sensitive applications.
Standby power consumption, using Fairchild's uSerDes, is 10 times lower than any other solution, a critical parameter affecting battery life and cellphone talk time.
FIN12 and FIN24 devices can reduce EMI by 30 to 40dB at the fundamental frequency as well as reduce troublesome harmonics to less than -100dBm, resulting in greater EMC.
These groundbreaking enhancements are achieved through serialisation architectural innovations and by offering two innovative differential I/O technologies, low power LVDS (LpLVDS) and current transfer logic (CTL), that reduce power and EMI compared with traditional I/O technology.
'As the leading market innovator in high-performance serialisation solutions for ultraportables, Fairchild's new uSerDes devices are the first in a complete series that will broaden the serdes market', said Mike Fowler, member technical staff.
'Developed in close cooperation with a number of key customers, uSerDes provides designers with an excellent migration path to superior performance and functionality, including more efficient power management, lower EMI and smaller packaging'.
These lead (Pb)-free products meet or exceed the requirements of the joint IPC/JEDEC J-STD-020B standard and are compliant with the European Union requirements now in effect.
