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 (typ) Bandwidth: 12 GHz (typ) Very low DDNEXT crosstalk: < -37 dB at 5 GHz VIC common mode input voltage VIC: 0 V to 2 V Differential input voltage VID: <1.6 V Intra-pair skew: <6 ps VDD Power Supply voltage range: 1.62 V to 3.63 V Low current consumption: 200 A (typ) for active mode 3 A (typ) for power-saving CMOS SEL and XSD pins Back current protection on all I/O pins of these switches Patent pending high performance analog pass-gate technology All channels support rail-to-rail input voltage (up to 2.4 V) HUQFN16 1.6 mm 2.4 mm 0.5 mm package with 0.4 mm pitch ESD: 2000 V HBM 1000 V CDM Operating temperature range: -40 C to 85 CNXP Semiconductors CBTU02043 High-speed differential 1-to-2 switch 3 Application diagram Type-C system cable Type-C receptacle USB 2.0 D+ D- PHY CBTU02043 TX1P SSTX1 TX1N USB 3.0 PHY RX1P RX1N TX2P APPLICATION TX2N PROCESSOR RX2P RX2N SEL orientation VCONN power I2C GPIO GPIO 2.7V OUT CC1 CC PIN 11 PTN5150A OTG CC2 VCONN PMIC VBUS (4 traces) 5V OUT OTG VBUS DET 5V CHARGE aaa-022004 Figure 1.Application diagram 4 Ordering information Table 1.Ordering information Type number Topside Package marking Name Description Version CBTU02043HE 43 HUQFN16 Plastic, super thin quad flat package no leads 16 SOT1832-1 terminals body 1.6 mm x 2.4 mm x 0.5 mm 0.4 mm pitch 4.1 Ordering options Table 2.Ordering options Type number Orderable part Package Packing method Minimum order Temperature number quantity CBTU02043HE CBTU02043HEJ HUQFN16 REEL 13 Q1/T1 10000 T = -40 C to +85 C amb *STANDARD MARK SMD CBTU02043 All information provided in this document is subject to legal disclaimers.
