CBTU02043

CBTU02043 High-speed differential 1-to-2 switch Rev. 3.1 — 23 September 2021 Product data sheet 1 General description CBTU02043 is a high-speed differential 1-to-2 switch chip optimized to interface with USB Type-C connector for mobile and PC applications. This high performance switch chip can be used for single port USB3.1, PCIe-Gen3, MIPI high-speed serial interface applications. It can also support DP1.4 or 4 single-ended DDR channels. The CBTU02043 chip can also provide 2-to-1 MUX function by selecting 1 (Port A) out of two differential ports (Port B or C) for other applications. The pinouts are optimized for USB3.1 Type-C DeMUX application and achieve very low crosstalk to meet the stringent USB Type-C crosstalk spec. The small package and pinning is ideal for smartphone USB Type-C application. CBTU02043 is available in 1.6 mm x 2.4 mm x 0.5 mm HUQFN16 package with 0.4 mm pitch. 2 Features and benefits Optimized for USB Type-C connector PCB routing for signal integrity – Minimize crosstalk to meet stringent USB Type-C requirement – Minimize via with friendly USB Type-C PCB layout One port (two bidirectional differential channels) 1-to-2 switch – Low insertion loss: -1.4 dB at 5 GHz; -0.9 dB at 2.5 GHz; -0.5 dB at 100 MHz – Low off-state isolation: -20 dB at 5 GHz; -40 dB at 100 MHz – Low return loss: -16 dB at 2.5 GHz; -12 dB @ 5 GHz – Low ON-state resistance: 10 Ω (typ) – Bandwidth: 12 GHz (typ) – Very low DDNEXT crosstalk: < -37 dB at 5 GHz – VIC common mode inpu...
