FSA641UMX

Signal Switches, Multiplexers, Decoders Overview

The FSA641UMX is a 2:1 MIPI switch featuring a configuration of two data lanes and one clock lane. It operates on a single supply voltage ranging from 2.65 V to 4.3 V. The device supports a -3dB bandwidth of 1 GHz and has a maximum on-resistance of 14 Ohm. It functions within an operating temperature range of -40°C to 85°C (TA). The component is housed in a 20-lead MLP package.

• Mobile phone camera module selection
• Display interface routing

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the manufacturer marking code, typically 'F6' or similar identifiers found on the top surface, against official ON Semiconductor documentation. Confirm the package type is 20-UMLP (Ultra Mini Leadless Package) and check for specific ordering suffixes if required by your bill of materials. Ensure the component meets the specified -40°C to 85°C operating temperature range for your application environment.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 2:1 multiplexer for MIPI signals is required with support for two data lanes and one clock lane. It is suitable for applications needing high bandwidth up to 1 GHz and low on-resistance. Consider the 20-lead MLP package size constraints and the 2.65 V to 4.3 V supply voltage requirements during circuit design.

Signal Switches, Multiplexers, Decoders Part Context

The FSA641UMX belongs to the FSA64x series of MIPI switches manufactured by Fairchild Semiconductor, now part of ON Semiconductor. This series includes variants like the FSA644 and FSA646, which offer different lane configurations such as 4-data lane options. The FSA641 specifically targets applications requiring a balance between data lane count and clock lane support in mobile and portable devices.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Potential substitutes include the FSA644UCX for 4-data lane applications or TS5MP645/TS5MP646 from Texas Instruments for similar 2:1 analog switch functionality. Verify pin compatibility and electrical specifications before substitution.
