HD3SS214ZXHR

Analog Switches - Special Purpose Overview

The HD3SS214ZXHR is a high-speed passive differential switch supporting DisplayPort 1.4 electrical standards with data rates up to 8.1 Gbps. It provides 2:1 and 1:2 switching configurations for four high-speed lanes, HPD, AUX, and DDC signals. The device operates on a single 3.3 V supply (3 V to 3.6 V) within an extended industrial temperature range of -40°C to 105°C. Key electrical parameters include an 8 GHz differential bandwidth, typical active power consumption under 2 mW, and standby current below 10 µW when the OE pin is low. It utilizes a 5 mm x 5 mm 50-ball nFBGA package.

Analog Switches - Special Purpose Feature Summary

• Supports DisplayPort 1.4 electrical standard with 8.1 Gbps data rate capability
• Switches high-speed lanes alongside HPD, AUX, and DDC signals
• Features independent adaptive common mode tracking for simplified system implementation
• Includes output enable pin to reduce power consumption in standby mode

Analog Switches - Special Purpose Applications

• PC and notebook motherboards requiring dual GPU selection
• Tablets and connected peripherals needing source switching
• Docking station implementations with DP++ support

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix ZXHR corresponds to the nFBGA-50 package variant. Confirm that the component meets the required RoHS compliance status and moisture sensitivity level specifications for the intended manufacturing process. Ensure the design accounts for the extended industrial temperature range limits defined in the datasheet.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring seamless switching between two DisplayPort sources or sinks at high data rates. It is suitable for applications needing integrated AUX and DDC signal routing without external multiplexers. Consider the 5 mm x 5 mm footprint constraints and the requirement for a stable 3.3 V supply during operation.

Analog Switches - Special Purpose Part Context

The HD3SS214 belongs to Texas Instruments' family of high-speed analog switches designed for video interfaces. It serves as a critical interface component for managing multiple display outputs in compact electronic devices. The ZXH suffix specifically denotes the nFBGA package type, which replaced earlier MicroStar Jr. BGA designs while maintaining footprint compatibility.
