HD3SS460RHRT

HD3SS460RHRT is a Texas Instruments high-speed signal switch in the HD3SS family. It provides one or more high-speed differential-channel switches (mux/demux) to route SuperSpeed USB, HDMI/DP lanes, and other high-speed differential signals inside mobile/embedded systems, docks, or automotive electronics. The “RHRT” suffix denotes a RoHS-compliant, high-reliability package variant.
Key points
- High-speed differential-path switching with low insertion loss
- Configurable channel routing via small control lines and an enable pin
- Integrated ESD protection and compact package
- Suitable for mobile, embedded, docking, and automotive applications
For exact specs (number of channels, data rates, voltage ranges, pinout, timing), refer to the HD3SS460RHRT datasheet and TI design resources.

HD3SS460RHRT is Renesas’ HDMI 2.0 4-lane retimer/switch. There aren’t publicly published exact cross-references. For a replacement, use Renesas’ cross-reference tool or distributor search. Possible alternatives include HDMI 2.0 retimers from Parade Technologies (PTN-series) or other vendors’ HDMI 2.0 retimers that match your electrical/timing requirements; verify pinout, power rails, and signals before substitution.

HD3SS460RHRT features (highlights):
- 4-lane HDMI 2.0 TMDS retimer: re-times and equalizes all four TMDS lanes (including clock) to extend cable length and improve signal integrity.
- HDMI 2.0 bandwidth support: up to 18 Gbps TMDS (6 Gbps per lane).
- Programmable per-lane equalization and pre-emphasis for better link quality over long cables.
- I2C control interface for configuration and status; DDC/EDID pass-through.
- Hot-plug detect (HPD) and 5V hot-plug support; 3.3V logic with I/O tolerance suitable for HDMI signaling.
- ESD protection on TMDS lines; robust protection for interfaces.
- Low-power operation with power-down modes when inactive.
- RoHS-compliant packaging (RHT/tape-and-reel variant indicated by suffix).
- Industrial temperature range (typical for HDMI interface ICs) or as specified in datasheet.
Note: Exact pinout, voltage rails, and feature set (e.g., HDCP/CEC specifics) should be confirmed in the latest TI datasheet for HD3SS460RHRT.

Pin count: 20 pins (20‑pin package, QFN).
Function: A high‑speed differential switch/multiplexer (dual 2:1) used to route one of two differential input pairs to a single output, typically for MIPI/DSI or HDMI-type high‑speed data paths.

Manufacturer: Renesas Electronics Corporation.
What kind of company: A Japanese multinational semiconductor company that designs and manufactures a wide range of ICs, including microcontrollers, analog, power, and automotive ICs for automotive, industrial, and consumer markets.

HD3SS460RHRT is a high-speed interface routing/retiming device for MIPI CSI-2/DSI and HDMI/DisplayPort paths used in USB‑C/DP Alt Mode systems. Common application areas include:
- USB-C docking stations and hubs (Alt Mode video paths)
- External displays and portable monitors (HDMI/DP bridges)
- Mobile devices (smartphones/tablets/laptops with MIPI camera/display subsystems)
- Automotive infotainment and camera/display subsystems
- Industrial/embedded video interfaces and display modules
It enables reliable, flexible routing and timing for high-speed video/data in these platforms.

HT3SS460RHRT is in an HTSSOP-8 (8-pin) package, tape-and-reel (RT) packaging.
