Fairchild's Camera Isolation Switch for Portable Devices

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./
