CBTL02042ABQ,115

Overview

The CBTL02042ABQ,115 is a 3.3 V multiplexer/demultiplexer switch IC featuring two bidirectional differential channels with a 2:1 configuration. It supports high-speed signal switching for PCI Express Gen2 at 5 Gbit/s and offers a bandwidth of 7 GHz at -3 dB. The device operates within a supply voltage range of 3.0 V to 3.6 V and maintains an operating temperature range from -40 °C to +85 °C. Key electrical parameters include a maximum on-state resistance of 6 Ω, typical propagation delay of 80 ps, and standby current less than 1 μA in shutdown mode.

Feature Summary

Provides low insertion loss and minimal channel-to-channel skew for high-speed serial interfaces
Includes a dedicated shutdown pin to minimize power consumption during inactive periods
Features optimized pinouts for edge connectors or inter-connector placement

Applications

PCI Express Generation 2 signal routing
DisplayPort 1.2 interface expansion
USB 3.0 signal multiplexing
SATA 6 Gbit/s data path switching

Procurement Notes

Verify the specific suffix '115' against the manufacturer's official ordering information to confirm packaging details such as reel size or tape-and-reel specifications. Ensure the DHVQFN20 package dimensions align with the target PCB footprint design requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring low attenuation for PCIe Gen2 or USB 3.0 signals. Consider the CBTL02042A variant for edge connector layouts and the CBTL02042B variant for applications placing the switch between two connectors. Verify that the 3.3 V supply voltage matches the system architecture.

Part Context

This part belongs to the CBTL02042 series of high-speed differential switches designed by NXP Semiconductors. It is specifically engineered for PCI Express Generation 2 applications, offering a compact solution for expanding high-speed ports while maintaining signal integrity through minimized impedance and crosstalk characteristics.
