The device provides the option to choose the USB only implementation where SBU ports are in tri-state. 8.3.3 Output Enable and Power Savings The HD3SS460 has two power modes, active/normal operating mode and standby/shutdown mode. During standby mode, the device consumes very little current to save the maximum power. To enter standby mode, the EN control pin is pulled low and must remain low. For active/normal operation, the EN control pin should be pulled high to VDD through a resistor or dynamically controlled to switch between H or M. HD3SS460 consumes <2 mW of power when operational and <5 µW in shutdown mode, exercisable by the EN pin. 8.4 Device Functional Modes 8.4.1 Device High Speed Switch Control Modes Table 1.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information HD3SS460 can be utilized for a wide range of muxing needs. This is general purpose passive cross-point switch. The channels have independent adaptive common mode tracking allowing flexibility. As long as recommended electrical use conditions are met the device can be used number of ways as described in Table 1. NOTE HD3SS460 does not provide common mode biasing for the channel. Therefore it is required that the device is biased from either side for all active channels. 9.2 USB SS and DP as Alternate Mode HD3SS460 can be used USB Type-C ecosystem with DP as alternate mode in two distinct application configurations – one is for DP Source/USB Host, the other one for the DP Sink/USB Device/Dock. Figure 3 and Figure 4 illustrate typical application block diagrams for these two cases. Detail schematics are illustrated in Detailed Design Procedure section. Other applications and or use cases possible where these examples can be used as general guidelines. Figure 3 and Figure 4 depict the AC coupling capacitor placement examples. TI recommends placing the capacitors as shown in the illustrations for the backward compatibility and interoperability purposes as some of the existing USB systems may present Vcm, exceeding the typical range of 0–2 V on SS differential pairs.

However it is recommended that EN is asserted low after device supply VCC is stable and within specification. It is also recommended that ample decoupling capacitors are placed at the device VCC near the pin. 22 Submit Documentation Feedback Copyright © 2015–2016, Texas Instruments Incorporated Product Folder Links: HD3SS460 HD3SS460 www.ti.com SLLSEM7B – JANUARY 2015 – REVISED JUNE 2016 11 Layout 11.1 Layout Guidelines High performance layout practices are paramount for board layout for high speed signals to ensure good signal integrity. Even minor imperfection can cause impedance mismatch resulting reflection. Special care is warranted for traces, connections to device, and connectors. 11.1.1 Critical Routing The high speed differential signals must be routed with great care to minimize signal quality degradation between the connector and the source or sink of the high speed signals by following the guidelines provided in this document. Depending on the configuration schemes, the speed of each differential pair can reach a maximum speed of 5.4 Gbps. These signals are to be routed first before other signals with highest priority. • Each differential pair should be routed together with controlled differential impedance of 85 to 90-Ω and 50-Ω common mode impedance. Keep away from other high speed signals. The number of vias should be kept to minimum. Each pair should be separated from adjacent pairs by at least 3 times the signal trace width. Route all differential pairs on the same group of layers (Outer layers or inner layers) if not on the same layer. No 90 degree turns on any of the differential pairs. If bends are used on high speed differential pairs, the angle of the bend should be greater than 135 degrees. • Length matching: – Keep high speed differential pairs lengths within 5 mil of each other to keep the intra-pair skew minimum. – The inter-pair matching of the differential pairs is not as critical as intra-pair matching. The SSTX and SSRX pairs do not have to match while they need to be routed as short as possible. • Keep high speed differential pair traces adjacent to ground plane. • Do not route differential pairs over any plane split • ESD components on the high speed differential lanes should be placed nearest to the connector in a pass through manner without stubs on the differential path. In order to control impedance for transmission lines, a solid ground plane should be placed next to the high- speed signal layer. This also provides an excellent lowinductance path for the return current flow. – Placement recommendation would be: Connector – ESD Components --- HD3SS460 • For ease of routing, the P and N connection of the USB3.1 differential pairs to the HD3SS460 pins can be swapped as long as the corresponding pairs are swapped on the other end of the switch The example is shown in the reference EVM schematics section of this document. The P/N can be swapped on USB 3.1 connection of the switch for ease of routing purposes. 11.1.2 General Routing/Placement Rules • Route all high-speed signals first on un-routed PCB: SSTXP/N, SSRXT/N, LNAP/N, LNB P/N, LNC P/N, LND P/N, CTX*P/N. The stub on USB2 D+ and D- pairs should not exceed 3.5mm. • Follow 20H rule (H is the distance to reference plane) for separation of the high-speed trace from the edge of the plane • Minimize parallelism of high speed clocks and other periodic signal traces to high speed lines • All differential pairs should be routed on the top or bottom layer (microstrip traces) if possible or on the same group of layers. Vias should only be used in the breakout region of the device to route from the top to bottom layer when necessary. Avoid using vias in the main region of the board at all cost. Use a ground reference via next to signal via. Distance between ground reference via and signal need to be calculated to have similar impedance as traces. • All differential signals should not be routed over plane split. Changing signal layers is preferable to crossing plane splits. • Use of and proper placement of stitching caps when split plane crossing is unavoidable to account for highfrequency return current path • Route differential traces over a continuous plane with no interruptions. • Do not route differential traces under power connectors or other interface connectors, crystals, oscillators, or any magnetic source. • Route traces away from etching areas like pads, vias, and other signal traces. Try to maintain a 20 mil keepout distance where possible.

Care should be taken to minimize the stub length of the trace connecting the capacitor to the power pin. Avoid sharing vias between multiple decoupling capacitors. Place vias as close as possible to the decoupling capacitor solder pad. Widen VCC/GND planes to reduce effect of static and dynamic IR drop. The VBUS traces/planes must be wide enough to carry maximum of 2 A current. 11.2 Layout Example Figure 20, Figure 21, and Figure 22 illustrate some guidelines for layout. Actual layout should be optimized for various factors such as board geometry, connector type, and application. Figure 20. USB Type C Connector to HD3SS460 Signal Routing Figure 21.

(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
