CBTU02043 Block Diagram

CBTU02043 is a high performance switch chip that supports DP1.3 or 4 single-ended DDR channels. It is a high-speed differential 1-to-2 switch chip and able to provide 2-to-1 MUX function by selecting 1 (Port A) out of two differential ports (Port B or C) for other applications. The device’s pinouts are optimized for USB3.1 type C DeMUX application and achieve very low crosstalk to meet the stringent type C crosstalk spec. CBTU02043 is available in 1.6 mm x 2.4 mm x 0.5 mm HUQFN16 package with 0.4 mm pitch.
