CBTU02043HEJ

The CBTU02043HEJ from NXP Semiconductors is a high-speed differential 1-to-2 switch chip optimized for USB Type-C connector interfaces in mobile and PC applications. This switch chip is suitable for single-port USB3.1, PCIe-Gen3, and MIPI high-speed serial interface applications. It can also support DP1.4 or 4 single-ended DDR channels, and provides a 2-to-1 MUX function.

Key electrical specifications include a bandwidth of 12 GHz, low insertion loss of -0.5 dB at 100 MHz and -1.4 dB at 5 GHz, and low off-state isolation of -40 dB at 100 MHz. The ON-state resistance is typically 10 Ω, with very low DDNEXT crosstalk below -37 dB at 5 GHz. The device operates over a wide power supply voltage range of 1.62 V to 3.63 V and features low current consumption, with 200 μA in active mode and 3 μA in power-saving mode.

The pinouts are optimized for USB3.1 Type-C DeMUX applications, minimizing crosstalk to meet stringent USB Type-C requirements. The CBTU02043HEJ is available in a compact 1.6 mm x 2.4 mm x 0.5 mm HUQFN16 package with a 0.4 mm pitch, making it ideal for smartphone USB Type-C applications. It operates within an ambient temperature range of -40 °C to 85 °C.
