CBTL04082ABS,518

Overview

The CBTL04082ABS is a bidirectional differential channel multiplexer/demultiplexer switch designed for PCI Express Generation 2 applications. It switches four differential signals to one of two locations with negligible attenuation and minimized skew. The device operates at a supply voltage of 3.3 V ±10% and supports high-speed signal switching up to 5 Gbit/s. Key electrical parameters include a -3 dB bandwidth of 6 GHz, insertion loss of -0.5 dB at 100 MHz and -1.2 dB at 2.5 GHz, and low intra-pair skew of 5 ps typical. It features dual shutdown pins for independent channel control, standby current less than 1 μA, and ESD tolerance of 8 kV HBM and 1 kV CDM.

Feature Summary

• Supports high-speed signal switching for PCIe Gen2 with minimal signal attenuation
• Features dual shutdown pins for independent power management of channel groups
• Provides low intra-pair and inter-pair skew for precise signal integrity

Applications

• Routing of high-speed differential signals in PCIe Gen2 systems
• DisplayPort 1.2 signal routing
• USB 3.0 interface expansion
• SATA 6 Gbit/s signal switching

Procurement Notes

Verify the specific ordering suffix '518' against official NXP documentation to confirm package variant or tape-and-reel specifications. Ensure compatibility with HVQFN42 footprint requirements during procurement planning. Confirm that the component meets the required ambient temperature operating range of -40 °C to +85 °C for your specific application environment.

Selection Notes

Select this component when expanding existing high-speed ports with extremely low power consumption requirements. Choose between CBTL04082A and B variants based on layout constraints; A is suitable for edge connectors with different signal sources, while B allows placement between two connectors. Ensure the design accommodates the exposed thermal pad for proper heat conduction and electrical grounding.

Part Context

This part belongs to the CBTL04082A/B family of 3.3 V, 4 differential channel, 2:1 multiplexer/demultiplexer switches. It is specifically optimized for PCI Express Generation 2 applications, offering high bandwidth and low crosstalk. The ABS suffix indicates the HVQFN42 package version, which is a plastic thermal enhanced very thin quad flat package with no leads.
