CBTL02042BBQ,115

Overview

The CBTL02042BBQ,115 is a 3.3 V multiplexer/demultiplexer switch featuring two bidirectional differential channels with a 2:1 configuration. Designed for high-speed serial interfaces like PCI Express Gen2, it operates within a supply voltage range of 3.0 V to 3.6 V. The device provides a bandwidth of 7 GHz at -3 dB and maintains an on-state resistance of 6 Ω. It supports signal rates up to 5 Gbit/s with low insertion loss of -1.2 dB at 2.5 GHz. Key electrical parameters include a propagation delay of 80 ps, intra-pair skew of 5 ps typical, and inter-pair skew of 35 ps maximum. Supply current reaches 2.5 mA maximum in active mode.

Feature Summary

• Optimized pinout layout for edge connectors or between dual connectors
• Integrated shutdown function for power-saving standby modes
• High ESD tolerance supporting robust system protection

Applications

• PCI Express Generation 2 signal routing
• USB 3.0 high-speed data switching
• DisplayPort 1.2 interface expansion

Procurement Notes

Verify the specific ordering suffix matches the required package variant DHVQFN20. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement plans. Ensure the component meets environmental standards relevant to the target deployment region.

Selection Notes

Select this model when board space requires outputs on both sides of the package for multiplexing signals between two connectors. The CBTL02042ABQ variant is suitable only if input and output pins must be located on opposite package sides. Verify that the application requires a 3.3 V operating voltage and PCIe Gen2 speed capabilities.
