Description

The FSA642 is a bi -directional, low -pow er, high-speed analog sw itch. The pin out is designed to ease differential signal layout and is configured as a triple - pole, double -throw sw itch (TPDT). The FSA642 is optimized for sw itching betw een tw o MIPI devices, such as cameras or LCD displays and on -board Multimedia Application Processors (MAP). The FSA642 is compatible w ith the requirements of Mobile Industry Processor Interface (MIPI). The low - capacitance design allow s the FSA642 to sw itch signals that exceed 500 MHz in frequency. Superior channel -to- channel crosstalk immunity minimizes interference and allow s the transmission of high-speed differential signals and single -ended signals, as described by the MIPI specification.

The input and output negative ratings may be exceeded if the input and output diode current ratings are observed. Recommended Operating Conditions The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal per formance to the datasheet specifications.
