NL3HS644FCTAG

Analog Switches - Special Purpose Overview

The NL3HS644FCTAG is a single-pole double-throw (SPDT) switch designed for MIPI D-PHY applications, supporting data rates up to 1.5 Gbps. It switches between two high-speed or low-power MIPI sources and connects to CSI or DSI modules. Operating with a supply voltage of 1.65 V to 4.5 V, it features typical on-resistance of 8 Ω for HS MIPI and 7.9 Ω for LP MIPI. The device provides -27 dB off-isolation and -28 dB crosstalk at 750 MHz, with a bandwidth of 1,050 MHz. It utilizes a 36-ball WLCSP package measuring 2.36 mm x 2.36 mm.

Analog Switches - Special Purpose Feature Summary

• Supports switching between two MIPI sources for CSI or DSI module connections
• Optimized for MIPI specifications with low on-resistance and flatness
• Provides high off-isolation and low crosstalk for signal integrity
• Compatible with both high-speed and low-power MIPI modes

Analog Switches - Special Purpose Applications

• Mobile phone camera and display interfaces
• MIPI D-PHY signal routing in portable devices
• CSI/DSI module connection switching

Analog Switches - Special Purpose Procurement Notes

Verify the ordering suffix FCTAG corresponds to the standard 36-ball WLCSP Pb-Free package with a tape and reel quantity of 3000 units. Confirm that the backside coating variant (BFCTAG) is not required for the specific application, as the standard version lacks this feature. Ensure compatibility with the CASE 567LR package dimensions during PCB layout.

Analog Switches - Special Purpose Selection Notes

Select the NL3HS644FCTAG when a low-profile SPDT switch is needed for MIPI D-PHY signals up to 1.5 Gbps. Consider the BFCTAG variant if backside coating is necessary for thermal management or mechanical stability. Verify that the 1.65 V to 4.5 V supply range matches the system voltage requirements and that the 36-ball WLCSP footprint fits the design constraints.

Analog Switches - Special Purpose Part Context

The NL3HS644 is part of onsemi's portfolio of MIPI switches designed for mobile and portable electronics. It complements other signal routing components by providing dedicated support for MIPI D-PHY standards. The device is manufactured using advanced semiconductor processes to ensure low power consumption and high performance in compact form factors suitable for modern mobile devices.

Analog Switches - Special Purpose Replacement Considerations

The NL3HS644BFCTAG is a direct alternative with identical electrical characteristics but includes a backside coating. Verify package compatibility and functional equivalence before substitution. No other cross-model replacements are documented in the official datasheet.
