CBTL08GP053EVY

Overview

The CBTL08GP053EVY is a USB Type-C high-performance crossbar switch IC designed for passive switching of high-speed differential and single-ended signals. It supports interface standards including USB 3.1 (10 Gbps), DisplayPort 1.3 (8.1 Gbps), and PCI Express 3.0 (8 Gbps). The device operates from a single 3.3 V power supply with typical active current consumption of 300 µA and standby current of 15 µA maximum. It features an I2C-bus interface for configuration, supporting Standard mode (100 kbit/s) and Fast mode (400 kbit/s). The component is housed in a VFBGA40 package measuring 4.75 mm × 3.25 mm with a 0.5 mm pitch.

Feature Summary

• Supports multiplexing and switching of high-speed differential signals up to 10 Gbps for USB 3.1, DP 1.3, and PCIe 3.0 interfaces.
• Includes sideband auxiliary crossbar switches capable of handling 5.5 V tolerant single-ended signals such as AUX, UART, or I2C.
• Provides direction-agnostic switch paths selectable via an I2C-bus interface with programmable slave addresses.
• Features back current protection on control pins and exposed connector side I/O pins.

Applications

• Notebook PCs, ultrabooks, and desktop PC platforms
• Tablets, 2:1 convertibles, and smartphones
• PC accessories and peripherals such as multi-function monitors and docks

Procurement Notes

Verify the ordering part number CBTL08GP053EVY corresponds to the VFBGA40 package variant. Confirm the operating temperature range requirements align with the specified -40 °C to +85 °C ambient temperature limit. Ensure the design accommodates the 3.3 V single power supply requirement and I2C bus voltage levels for proper system integration.

Selection Notes

Select this component when designing Type-C connectors requiring passive switching of USB 3.1, DisplayPort, or PCIe signals. It is suitable for applications needing low insertion loss and high isolation for high-speed data integrity. Consider the VFBGA40 package size constraints and the need for I2C-based dynamic path configuration during system initialization.

Part Context

This component belongs to NXP's portfolio of USB Type-C interface solutions. It complements other high-speed signal switches like the CBTL02043ABQ family by offering a higher pin count and dedicated sideband management for complex Type-C configurations involving multiple protocol alternates.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official NXP channels for qualified alternatives if sourcing becomes unavailable.

FAQ

What is the default state of the switches upon power-on reset?

At power-on reset, all switches are in a High-Impedance (Hi-Z) condition until configured by the host processor via the I2C interface.

How many I2C slave address options does the CBTL08GP053 support?

The device supports up to four I2C-bus slave address options, which are selected using the SLV_ADDR1 and SLV_ADDR2 pins.

Is the SW_EN pin required to reset I2C register contents?

No, toggling the SW_EN pin LOW disables the switch paths but does not reset the I2C register contents; it only forces outputs to Hi-Z.
