CBTL04083ABS,518

Overview

The CBTL04083ABS,518 is a 3.3 V, 4 differential channel, 2-to-1 multiplexer/demultiplexer switch designed for PCI Express Generation 3 applications. It switches four differential signals to one of two locations with negligible attenuation and minimized skew. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports an ambient temperature range from -40 °C to +85 °C. Key electrical parameters include a typical intra-pair skew of 5 ps, maximum inter-pair skew of 35 ps, and a -3 dB bandwidth of 8.0 GHz. ESD tolerance is rated at 2000 V HBM and 1000 V CDM.

Feature Summary

• Supports high-speed signal switching for 8.0 Gbit/s PCIe Gen3 speed
• Features low intra-pair skew and low inter-pair skew for signal integrity
• Includes dual shutdown pins for independent channel power management
• Offers high ESD tolerance for robust operation

Applications

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

Procurement Notes

Verify the ordering suffix '518' corresponds to the specific tape width required for your automated assembly line. The datasheet indicates that '518' denotes a 16 mm wide carrier tape, while '558' denotes a 24 mm wide carrier tape. Ensure the selected variant matches your pick-and-place equipment specifications before finalizing procurement orders.

Selection Notes

Select the CBTL04083ABS over the BBS variant if the application requires input and output pins on opposite sides of the package, which is suitable for edge connectors with different signal sources on the motherboard. Verify that the system design utilizes a 3.3 V supply rail and requires independent shutdown control for channel groups 0/1 and 2/3 to meet power consumption targets.

Part Context

This component belongs to the CBTL04083A/B family of high-speed multiplexer switches. It is specifically engineered for PCI Express Generation 3 environments where low insertion loss and minimal crosstalk are critical. The ABS suffix identifies the specific pinout configuration optimized for certain motherboard layouts compared to the BBS version.
