CBTL06121BHF,518

Overview

The CBTL06121BHF 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, AC-coupled signals using high-bandwidth pass-gate technology. Additionally, it supports Hot Plug Detect (HPD) signal routing as well as AUX or DDC signal switching, totaling six channels. The device operates at 2.5 Gbit/s for PCI Express or 2.7 Gbit/s for DisplayPort. It features a single 3.3 V power supply, very low operating current of 0.2 mA typical, and shutdown current under 10 μA. The component is housed in an 11 mm × 5 mm HWQFN56R package.

Feature Summary

• Supports 1:2 multiplexing of DisplayPort or PCI Express signals with four high-speed differential channels
• Includes dedicated channels for HPD and AUX/DDC signal routing
• Features high-bandwidth analog pass-gate technology with very low intra-pair and inter-pair skew
• Provides latchable MUX position select and CMOS input shutdown mode to minimize power consumption

Applications

• Motherboard applications requiring DisplayPort and PCI Express switching/multiplexing
• Docking stations for mobile platforms
• Notebook computers utilizing configurable I/O pins
• Chip sets requiring flexible allocation of PCI Express or DisplayPort I/O pins to board connectors

Procurement Notes

Verify the specific pinout variant required for your design, as the 'B' suffix indicates the B pinout configuration available as a separate ordering part number from the A pinout. Confirm that the HWQFN56R package dimensions align with your PCB footprint requirements. Ensure the system controller chip utilizes I/O pins configurable for either PCI Express or DisplayPort operation to properly utilize the 1:2 multiplexer topology.

Selection Notes

Select this component when designing systems that require routing Gen1 DisplayPort or PCI Express signals between a multi-mode display source and different connectors. The device is suitable for applications needing flexible allocation of I/O pins. Consider pairing with HDMI/DVI level shifters if dual connectivity support is required. Verify that the motherboard layout accommodates the specific pinout configuration corresponding to the selected suffix.

Part Context

The CBTL06121 series consists of two distinct pinout variants, designated by the 'A' and 'B' suffixes, which are orderable as separate part numbers to accommodate different motherboard layout requirements. The CBTL06121BHF specifically refers to the version with the B pinout configuration. Both variants share identical functional characteristics but differ in physical pin arrangement within the HWQFN56R package.

Replacement Considerations
