RS2228XN

Overview

The RS2228XN is a high-speed, low-power double-pole/double-throw (DPDT) analog switch manufactured by Runic Technology. Designed for USB 2.0 signal switching, it operates within a supply voltage range of +1.8V to +5.5V and supports an extended industrial temperature range from -40°C to +85°C. The device features a typical on-resistance (RON) of 6Ω with a maximum of 10Ω at 25°C. It provides a -3dB bandwidth of 550MHz, turn-on time of 20ns, and turn-off time of 15ns. Key electrical characteristics include off-isolation of -35dB at 250MHz, channel-to-channel crosstalk of -40dB, and charge injection of 11pC. The component is available in MSOP-10 packaging.

Feature Summary

Supports high-speed USB 2.0 signals up to 480-Mbps with 550MHz bandwidth
Features break-before-make switching to prevent signal glitches
Includes bus-switch enable pin for high-impedance isolation and low power consumption
Operates with rail-to-rail input and output capabilities

Applications

Routing signals for USB 1.0, 1.1, and 2.0 interfaces
Portable instrumentation and digital cameras
Cell phones, PDAs, and set-top boxes
MP3 and other personal media players

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel quantity. The RS2228XN designation corresponds to the MSOP-10 package variant. Ensure compatibility with standard surface-mount assembly processes and observe ESD handling precautions during procurement and storage.

Selection Notes

Select this component when designing circuits requiring high-bandwidth analog switching for USB data lines. The DPDT configuration allows routing differential pairs between two sources or destinations. Consider the 6Ω typical on-resistance and 7pF on-capacitance for signal integrity analysis. Verify that the control logic levels align with the VIH and VIL specifications for reliable operation.

Part Context

The RS2228 series includes variants such as the QFN-1.4×1.8-10L package option. The RS2228XN specifically denotes the MSOP-10 version intended for surface-mount applications. This family targets consumer electronics and mobile devices where space constraints and power efficiency are critical design parameters.
