CBTL01023GM,115

Overview

The CBTL01023GM is a single differential channel, 2-to-1 multiplexer/demultiplexer switch designed for PCI Express Generation 3 (Gen3) and other high-speed serial interfaces. It operates with a VDD supply range of 3.0 V to 3.6 V (typical 3.3 V ± 10%). Key electrical parameters include a -3 dB bandwidth of 9 GHz, low insertion loss of -0.6 dB at 100 MHz and -1.5 dB at 4.0 GHz, and off-state isolation of -30 dB at 4 GHz. The device features an intra-pair skew of 5 ps typical, ESD tolerance of 2000 V HBM and 1000 V CDM, and a shutdown current of less than 1 µA. It is housed in an XQFN10 package.

Feature Summary

• Supports high-speed signal switching for PCIe Gen3 8 Gbit/s applications
• Provides a shutdown pin for power-saving mode with minimal standby current
• Minimizes impedance and crosstalk for negligible signal attenuation

Applications

• Routing of high-speed differential signals for PCIe Gen3
• DisplayPort 1.2 signal routing
• USB 3.0 interface expansion
• SATA 6 Gbit/s signal switching

Procurement Notes

Verify the specific ordering suffix '115' against official NXP documentation to confirm packaging details such as reel size or tape-and-reel specifications. Ensure the component status matches current production data sheets before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a single differential channel switch with low insertion loss and high bandwidth. Consider the XQFN10 package dimensions and thermal characteristics for PCB layout. Verify that the operating voltage aligns with the 3.3 V ± 10% requirement and that ESD protection levels meet system safety standards.

Part Context

The CBTL01023 is part of NXP's CBTL series of high-speed signal switches. This family includes variants like the CBTL02043 for dual-channel applications. These devices are engineered to expand existing high-speed ports while maintaining signal integrity in compact form factors suitable for modern embedded systems.

Replacement Considerations

Check for direct substitutes within the CBTL series, such as the CBTL01023A if available, ensuring identical pinout and electrical specifications. Verify compatibility with existing PCB footprints and control logic levels before substituting.
