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.
Feature Summary
- Supports 2-data and 1-data lane configurations for MIPI interfaces
- High-speed signal switching with 1 GHz bandwidth capability
- Low power operation enabled by wide single-supply voltage range
Applications
- MIPI D-PHY interface switching
- Mobile phone camera module selection
- Display interface routing
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.
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.
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.
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.
