Frequently Asked Questions
What maximum data rate does TMUXHS4212RKST support per channel?
TMUXHS4212RKST supports up to 16 Gbps per differential channel, with a nominal analog bandwidth of 13000 MHz. This makes it compatible with USB 3.2 Gen 2, PCIe Gen 3, and DisplayPort 1.4 signal levels without significant eye diagram degradation at full data rate.
How does the 2:1 mux configuration in TMUXHS4212RKST benefit USB-C port designs?
The 2-channel 2:1 SPDT configuration allows a single TMUXHS4212RKST to route two differential pairs from one of two source interfaces to a common output, saving 50% board area versus discrete solutions. In a USB-C design with 2 ports sharing one controller, the device switches 16 Gbps SuperSpeed lanes with minimal insertion loss, supporting full 10 Gbps USB 3.2 Gen 2 throughput.
What supply voltage and temperature range does TMUXHS4212RKST require?
TMUXHS4212RKST operates from a 1.8 V supply rail and supports commercial 0°C to 70°C ambient temperature range. The 1.8 V compatibility aligns with modern low-voltage I/O standards, reducing the need for level translators when interfacing with current-generation SoCs and FPGAs.
Which package does TMUXHS4212RKST use and how does that affect thermal and layout considerations?
TMUXHS4212RKST uses a 20-pin VQFN package, which provides an exposed thermal pad to improve heat dissipation at high signal frequencies. The small outline reduces PCB trace length, lowering parasitic inductance and capacitance that could degrade 13 GHz bandwidth performance in compact high-speed layouts.
