Serdes targets multimegapixel image sensors

Keywords:multimegapixel image sensors? Serdes device? CTL technology?

Fairchild Semiconductor introduced the FIN212AC, a ?Serdes device designed for serializing high-speed signals in multimegapixel-resolution CMOS and CCD image sensors, commonly found in portable products including cellphones with built-in cameras. The FIN212AC can be configured as a serializer or deserializer and is implemented in pairs. Patented CTL technology operates well in noisy RF environments by eliminating additional shielding required by similar high-speed signals while offering a low EMI of -110dBM. It is beneficial when used in portable electronics with clamshell and slider form factors, where minimizing the number of signals across a hinge reduces board space and improves reliability.

The device offers selectable LVCMOS edge rates and pulse width to increase design flexibility while minimizing EMI. These features allow the designer to tune to a particular frequency range and enable implementations for both RGB and ?Controller interfaces without requiring software modifications. Although primarily targeting 8bit to 12bit camera interfaces in cellphones, the FIN212AC is also well suited for applications with similar parallel interfaces up to 12bits, including laptops with integrated Web cams, VoIP phones and security cameras. Featuring a power-down mode of ~0.1?A when not transmitting data and aids in conserving battery life in portable applications. Additionally, the device's small BGA and MLP packages can be mounted on a PCB or directly on the flex. These Pb-free packages meet the requirements of the joint IPC/JEDEC standard J-STD-020C and are compliant with European Union regulations now in effect.

The device is already available with pricing beginning at $1.30 each in 1,000-piece quantities.
