CBTL06121AHF,518

Overview

The CBTL06121AHF,518 is a six-channel multiplexer designed for DisplayPort and PCI Express applications at Generation 1 speeds. It provides four differential channels capable of switching or multiplexing bidirectional and AC-coupled signals using high-bandwidth pass-gate technology. Additionally, it supports the switching of Hot Plug Detect (HPD) signals as well as AUX or DDC signals, totaling six channels. The device operates at 2.5 Gbit/s for PCI Express or 2.7 Gbit/s for DisplayPort. It utilizes a single 3.3 V power supply and features a shutdown mode to minimize power consumption. The component is available in an 11 mm × 5 mm HWQFN56R package.

Feature Summary

• Supports 1:2 multiplexing of DisplayPort or PCI Express Gen1 signals with four high-speed differential channels.
• Includes dedicated channels for AUX/DDC signals and Hot Plug Detect (HPD) functionality.
• Features very low intra-pair differential skew and inter-pair skew for signal integrity.
• Provides a latch function for switch position selection and a shutdown mode to reduce current consumption.

Applications

• Motherboard applications requiring DisplayPort and PCI Express switching/multiplexing
• Docking stations
• Notebook computers

Procurement Notes

Verify the specific pinout configuration required for your design, as the A and B suffixes correspond to distinct pinouts available as separate ordering part numbers. Confirm that the HWQFN56R package dimensions align with your PCB footprint requirements. Ensure the system controller chip I/O pins are configurable for either PCI Express or DisplayPort operation before implementation.

Selection Notes

Select this component when routing signals from a multi-mode display source to either a physical DisplayPort connector or a PCI Express connector on mobile platforms. It is suitable for designs where flexible allocation of I/O pins to board connectors is necessary. Consider pairing with HDMI/DVI level shifters if dual connectivity support is required.

Part Context

This component belongs to NXP's portfolio of high-speed signal switches and multiplexers. It is specifically engineered for Gen1 speed applications involving DisplayPort and PCI Express interfaces. The device addresses motherboard layout requirements by offering configurable pinouts to accommodate different board designs while maintaining signal integrity for high-speed serial data.

Replacement Considerations

The datasheet indicates that the 'A' and 'B' suffixes represent two different pinouts available as separate ordering part numbers. Designers must ensure the selected replacement matches the specific pinout (A or B) required by their motherboard layout constraints.
