Frequently Asked Questions
What is the maximum bandwidth of the TMUXHS4212IRKSR?
The TMUXHS4212IRKSR supports a nominal bandwidth of 13GHz (13000 MHz). This makes it capable of routing high-speed differential signals conforming to USB 3.1 Gen 2 (10Gbps), PCIe Gen 3 (8GT/s), and HDMI 2.0 (18Gbps) standards without significant signal attenuation.
What is the switching configuration of the TMUXHS4212IRKSR?
The TMUXHS4212IRKSR is configured as a 2:1 SPDT (Single Pole Double Throw) differential multiplexer. It can select between two differential signal pairs and route one to the output, making it ideal for applications where two signal sources must share a single downstream interface.
What package does the TMUXHS4212IRKSR use?
The TMUXHS4212IRKSR uses a 20-pin QFN (Quad Flat No-lead) package, designated JESD-30 code R-PQCC-N20. This compact, thermally efficient package minimizes parasitic inductance and capacitance, which is critical for maintaining signal integrity at multi-gigahertz frequencies.
What is the control voltage level for the TMUXHS4212IRKSR?
The TMUXHS4212IRKSR has a maximum input control voltage of 1.8V, making it directly compatible with 1.8V logic systems common in modern SoCs, FPGAs, and microcontrollers. No level shifting is required when interfacing with 1.8V digital control signals.
What types of applications is the TMUXHS4212IRKSR best suited for?
The TMUXHS4212IRKSR is best suited for high-speed signal path applications including USB Type-C controllers, Thunderbolt interface switches, PCIe lane multiplexing, and HDMI signal routing. Its 13GHz bandwidth and differential SPDT topology make it an ideal solution for any design requiring transparent multi-gigabit signal switching between two sources.
