CBTL03SB212BS,515

Overview

The CBTL03SB212 is a DisplayPort Gen2 sideband signal multiplexer designed for high-bandwidth pass-gate applications. It provides three channels: one differential channel for Fast AUX or AUX signals, one channel for DDC clock and data, and one channel for the Hot Plug Detect (HPD) signal. The device operates on a single 3.3 V power supply with a typical operating current of 0.2 mA and shutdown current under 10 μA. It features very low intra-pair differential skew of 5 ps typical and supports bidirectional switching. The component is housed in a 4 mm × 4 mm HVQFN20 package.

Feature Summary

• Supports 1:2 multiplexing of DisplayPort sideband signals including AUX, DDC, and HPD channels.
• Utilizes high-bandwidth analog pass-gate technology for bidirectional signal paths without requiring clock or reset signals.
• Includes a shutdown mode to minimize power consumption by switching all channels to a non-conducting state.

Applications

• Motherboard applications requiring DisplayPort sideband switching between multiple GPU sources.
• Docking stations managing display connectivity.
• Notebook computers integrating display output selection.

Procurement Notes

Verify the specific ordering suffix BS corresponds to the HVQFN20 plastic thermal enhanced very thin quad flat package variant. Confirm that the component status remains active as a product specification rather than an objective or preliminary draft. Ensure compatibility with lead-free reflow soldering processes if manufacturing requires compliance with specific environmental standards.

Selection Notes

Select this component when designing systems requiring multiplexing of DisplayPort Gen2 sideband signals such as AUX, DDC, and HPD. Ensure the design accommodates a single 3.3 V power supply and provides adequate thermal vias for the exposed center pad in the HVQFN20 package. Verify that the application environment stays within the specified ambient temperature range of -40 °C to +85 °C.
