Fairchild Semiconductor Introduces the First Camera Isolation Switch for Portable Devices

Fairchild Semiconductor (NYSE: FCS) brings designers of 3G
smartphones, netbooks, set-top boxes and notebooks the industry�s
first image module switch that isolates parasitic components to
maintain signal integrity. The FSA1211 is a 12-port, single pole,
single throw (SPST) analog switch that isolates the high speed bus
from parasitic components in dual camera applications. Smartphones
feature dual cameras and as these cameras move to higher and higher
resolutions, parasitic components play a critical role in
deteriorating signals and generating unwanted EMI.
With a bandwidth in excess of 720MHz and high ESD (5.5 kV), the
FSA1211 offers an optimal way to isolate capacitance and maintain
signal integrity for high speed data paths. In addition, when
isolating the unused parallel interface, the FSA1211 reduces the
radiated EMI of the path, improving RF desense. The traditional
parallel solution can deteriorate the signal due to the unwanted
�stub,� resulting in image degradation of the camera module.
Another approach is to use three analog switches, which complicates
design and adds to the overall bill of material (BOM) costs. In
contrast, the FSA1211 offers robust isolation and ease of design at
a lower cost.
The FSA1211 complements Fairchild�s comprehensive offering of
switch products used in portable and consumer applications. These
analog, audio, video and USB switches are instrumental in
minimizing redundant circuitry, eliminating connectors, simplifying
design and conserving space in designs. Offered in a variety of
functions, configurations, packages and performance levels,
Fairchild�s switches are pivotal in solving portable and consumer
design challenges.
