Overview
The CBTL05023 is a multiplexer/demultiplexer switch designed for DisplayPort v1.2 signals and Thunderbolt applications. It features an AUX MUX 2:1 switch for 1 Mbit/s differential AUX and DDC signals, and a DP MUX 2:1 switch for DPML (up to HBR2 at 5.4 Gbit/s) and low-speed DC coupled LSTX/LSRX signals. The device includes three control signal buffers (HPDOUT, CA_DETOUT, BIASOUT) and provides BIASOUT output control with DC-biasing pull-down resistors for external 10 Gbit/s channels. Powered by a single 3.3 V supply, it operates within a temperature range of 0 °C to 85 °C.
Feature Summary
- Supports DisplayPort Main Link up to HBR2 data rate of 5.4 Gbit/s
- Integrates a 2:1 switch for multiplexing differential AUX and DDC signals
- Includes dedicated buffers for HPD, CA_DET, and BIASOUT control signals
- Provides DC biasing pull-down resistors to facilitate external 10 Gbit/s channels
Applications
- Thunderbolt application interfaces
- DisplayPort v1.2 signal routing
- High-bandwidth analog pass-gate switching systems
Procurement Notes
Verify the specific ordering part number CBTL05023BS,118 against current NXP Semiconductors documentation to confirm availability and package details. Ensure that the HVQFN24 package dimensions and thermal pad requirements align with your printed circuit board layout specifications before finalizing procurement.
Selection Notes
Select this component when designing systems requiring multiplexing between DisplayPort Main Link and low-speed signals alongside AUX/DDC path selection. Confirm that the system operates on a single 3.3 V supply and requires support for HBR2 data rates. Verify that the operating temperature range of 0 °C to 85 °C meets the environmental constraints of the target application.
Part Context
The CBTL05023 belongs to NXP's portfolio of high-speed analog switches and multiplexers. It is specifically engineered for display interface applications, bridging the gap between standard DisplayPort protocols and Thunderbolt connectivity requirements. The device utilizes patent-pending high-bandwidth analog pass-gate technology to ensure signal integrity across multiple high-speed channels.
Replacement Considerations
Consult official NXP Semiconductors documentation for verified substitute part numbers. Do not assume functional equivalence with other multiplexer models without cross-referencing pinouts, electrical characteristics, and protocol support in the latest datasheets.
