South Portland, MaineFairchild Semiconductor Corp. has made two key enhancements to its latest µSerDes device, the FIN224AC 22-bit bi-directional serializer/deserializer (SerDes)it boosted ESD protection and further reduced EMI for cell phone and other wireless applications.
The FIN224AC µSerDes device uses the same footprint and base architecture as its popular predecessor, the FIN24AC, but offers ESD protection of 15-kV vs. 8-kV. The FIN224AC also implements rolled edge rates of the LVTTL outputs to further reduce EMI.
In addition, the FIN224AC offers a 20% reduction in power compared with the FIN24AC, according to the company. It offers multiple power-down modes100-nA in standby mode and 5-mA in typical operating conditions. Voltage translation is from 1.65-V to 3.6-V.

Fairchild's µSerDes products use patented low-power, low-EMI CTL technology to reduce 24 or 12 parallel LVTTL signals typically required in ultra-portables to a single differential serial signal. The technology eliminates the number of wires in an application, simplifying the design and saving space, while also removing problematic electromagnetic radiation from wide, high-speed data paths.
"Fairchild has worked closely with our customers to refine our SerDes technology and produce a device that addresses all their concerns while simplifying converging technologies into even smaller, thinner applications," says Chris Ferland, Fairchild's SerDes marketing manager, in a statement. "Fairchild's FIN224AC fulfills an important need in portable applications."
The FIN224AC is a lead (PB)-free device that meets or exceeds the requirements of the joint ICP/JEDEC standard J-STD-020C and is compliant with the European Union regulations now in effect.
In 1,000-unit quantities, the FIN224ACGFX in a BGA package is $1.74 and the FIN224ACMLX in an MLP is $1.66 each.
