CBTL06122BHF,518

Overview

The CBTL06122BHF is a six-channel multiplexer designed for DisplayPort and PCI Express Gen2 applications. It provides four differential channels capable of switching or multiplexing bidirectional, AC-coupled signals using high-bandwidth pass-gate technology. The device also switches Hot Plug Detect (HPD) and AUX/DDC signals. It operates on a single 3.3 V power supply with a typical operating current of 0.2 mA and shutdown current under 10 μA. Key electrical characteristics include an intra-pair differential skew of less than 5 ps, inter-pair skew under 180 ps, and a bandwidth of 4.0 GHz at the -5.0 dB intercept point.

Feature Summary

• Supports 1:2 multiplexing of DisplayPort (v1.1 - 2.7 Gbit/s) or PCI Express (Gen2 - 5.0 Gbit/s) signals
• Utilizes high-bandwidth analog pass-gate technology for low signal distortion
• Includes latch function for switch/multiplexer position selection
• Provides shutdown mode to minimize power consumption while switching all channels off

Applications

• Motherboard applications requiring DisplayPort and PCI Express Gen 2 switching/multiplexing
• Docking stations
• Notebook computers

Procurement Notes

Verify the specific pinout configuration required for the design, as the 'B' suffix indicates the B pinout variant available in the HWQFN56R package. Confirm that the system controller chip utilizes I/O pins configurable for either PCI Express or DisplayPort operation to ensure compatibility with the hex display MUX topology.

Selection Notes

Select this component when flexible allocation of PCI Express or DisplayPort I/O pins to board connectors is necessary. Ensure the application supports a single 3.3 V supply and requires low intra-pair skew for high-speed signal integrity. Consider the B pinout specifically if it aligns with the motherboard layout requirements compared to the A pinout variant.

Part Context

The CBTL06122 series includes two distinct pinout options, designated as A and B, which are orderable as separate part numbers to accommodate different motherboard layout constraints. The CBTL06122BHF specifically refers to the version with the B pinout configuration housed in a plastic thermal enhanced very very thin quad flat package without leads.

Replacement Considerations

The datasheet does not list direct replacement part numbers. Designers should evaluate alternative hex multiplexers from NXP or other manufacturers that support DisplayPort and PCIe Gen2 specifications, ensuring comparable bandwidth, skew characteristics, and pinout compatibility.
