Analog Switches - Special Purpose datasheet and documents for FSA642SUMX
Analog Switches - Special Purpose Overview
The FSA642SUMX is a bi-directional, low-power, high-speed analog switch configured as a triple-pole, double-throw (TPDT) device. It features a typical on capacitance of 7.0 pF and an on resistance of 7.0 Ω. The component provides a wide -3dB bandwidth of 1 GHz typical, enabling signal switching exceeding 500 MHz. It utilizes a 24-lead UMLP package measuring 2.5 x 3.4 mm. The device offers an 8 kV ESD rating for I/O pins and greater than 16 kV for power/ground connections.
Analog Switches - Special Purpose Feature Summary
- Optimized for differential signal layout to facilitate routing between MIPI devices and application processors
- Superior channel-to-channel crosstalk immunity minimizes interference for high-speed data transmission
- Compatible with Mobile Industry Processor Interface (MIPI) specifications for mobile multimedia applications
Analog Switches - Special Purpose Applications
- Dual camera applications for cell phones
- Dual LCD applications for cell phones
- Digital camera displays and viewfinders
Analog Switches - Special Purpose Procurement Notes
Verify the specific suffix 'SUMX' against official manufacturer documentation to confirm exact tape-and-reel packaging and temperature grade specifications. Ensure the ordering part number matches the required 24-lead UMLP variant. Cross-reference datasheet revisions to validate pinout consistency and electrical parameter tolerances before finalizing procurement orders.
Analog Switches - Special Purpose Selection Notes
Select this component when designing circuits requiring switching between two MIPI sources or destinations, such as dual cameras or displays. The low on-capacitance design is critical for maintaining signal integrity at frequencies above 500 MHz. Ensure the PCB layout accommodates the 2.5 x 3.4 mm footprint and supports the required 100-ohm differential impedance for optimal performance.
Analog Switches - Special Purpose Part Context
The FSA642 series belongs to ON Semiconductor's portfolio of multiplexers and crosspoint switches designed for high-speed data distribution. These devices are engineered for mobile handsets, media tablets, and storage peripherals. The family emphasizes fast switch times, low jitter, and fail-safe protection while meeting JEDEC latchup test standards for robust operation in consumer electronics.
Analog Switches - Special Purpose Replacement Considerations
Publicly confirmed substitute part numbers for the FSA642SUMX were not identified in available documentation. Verify compatibility with alternative TPDT switches by comparing pin configurations, package dimensions, and MIPI compliance requirements.
