TPD160221-QF3R-S

Overview

The TPD160221-QF3R-S is a dual differential channel 2:1 multiplexer/demultiplexer switch designed for high-speed serial interfaces. It supports data rates up to 16 Gbps with a -3 dB bandwidth of 12 GHz. The device operates on a single 3.3 V supply (3 V to 3.6 V) and features low insertion loss (-2.1 dB at 8 GHz) and low off-isolation (-10 dB at 8 GHz). It includes anti-backflow protection for control signals and data channels, ensuring safe operation during power-up or shutdown. The component functions within an industrial temperature range of -40°C to +85°C and is housed in a QFN2.5x4.5-20 package.

Feature Summary

• Supports high-speed signal switching up to 16 Gbps for PCIe Gen3/Gen4, DP 1.3/1.4, and USB 3.1/3.2
• Features two bidirectional differential channels configured as a 2:1 multiplexer/demultiplexer
• Includes anti-backflow protection for OE/SEL control pins and high-speed data channels
• Provides low intra-pair skew (10 ps max) and inter-channel skew (15 ps max)

Applications

• Notebooks, tablets, PCs, and servers
• Switches and routers
• OTN transport equipment
• Medical equipment
• Wireless infrastructure

Procurement Notes

Verify the specific ordering suffix 'QF3R-S' against the manufacturer's official documentation to confirm the tape and reel quantity and packaging details. Ensure that the selected variant matches the required operating temperature range and RoHS compliance status for your specific design implementation.

Selection Notes

Select this component when designing systems requiring 2:1 switching for differential signals with bit rates up to 16 Gbps. Consider its low skew characteristics for applications like multi-lane DisplayPort or USB configurations where timing alignment between channels is critical. Verify that the 3.3 V single-supply requirement aligns with the system power architecture.

FAQ

Does the TPD160221 include active signal conditioning?

No, the TPD160221 is a pure passive multiplexer/demultiplexer switch and does not contain active signal conditioning circuits such as equalizers or pre-emphasis.

How is the MUX/DEMUX channel selection controlled?

Channel selection is managed via the SEL pin. When SEL is Low, Port A connects to Port B. When SEL is High, Port A connects to Port C.

What is the maximum differential input voltage supported?

The recommended operating condition for the differential-mode input voltage is up to 1.8 Vpp. The absolute maximum rating for high-speed switch I/O voltage extends to min(4.6 V, VCC + 0.5 V).
