CBTU02043HEJ

Overview

The CBTU02043HEJ is a high-speed differential 1-to-2 switch optimized for USB Type-C connector interfaces in mobile and PC applications. It supports single-port USB 3.1, PCIe Gen 3, MIPI, DP 1.4, or four single-ended DDR channels. The device features low insertion loss (-1.4 dB at 5 GHz), low off-state isolation (-20 dB at 5 GHz), and very low DDNEXT crosstalk (< -37 dB at 5 GHz). It operates on a VDD supply voltage range of 1.62 V to 3.63 V with typical current consumption of 200 μA in active mode and 3 μA in power-saving mode. The component is housed in a HUQFN16 package (1.6 mm x 2.4 mm x 0.5 mm) and functions within an operating temperature range of -40 °C to +85 °C.

Procurement Notes

Verify the specific ordering suffix J corresponds to the REEL 13" Q1/T1 packing method when sourcing the CBTU02043HEJ variant. Confirm that the HUQFN16 package dimensions align with your PCB footprint requirements. Ensure the design accommodates the specified operating temperature range of -40 °C to +85 °C. Check for any recent revision updates to the datasheet regarding electrical characteristics before finalizing the bill of materials.

Selection Notes

Select this component for designs requiring a compact solution for high-speed differential signal routing in USB Type-C systems. The low intra-pair skew and minimal insertion loss make it suitable for maintaining signal integrity in dense mobile layouts. Consider the power-saving mode if battery life is a critical constraint in the target application environment.
