NXP Semiconductors CBTL02GP023HOZ

Overview

CBTL02GP023 from NXP Semiconductors is a one-port, 5 Gbps rail-to-rail low insertion loss 4× SPST analog switch IC optimized for USB3.0 signal routing with simultaneous high-voltage USB2/UART support in dongle and plug applications. It delivers −1.5 dB insertion loss at 2.5 GHz, 7 GHz bandwidth, and 11 Ω typical ON-state resistance while operating from 2.7 V to 3.5 V.

For engineers reviewing the CBTL02GP023 datasheet, CBTL02GP023 pinout, CBTL02GP023 application, or CBTL02GP023 equivalent, this page provides verified technical context, real-world USB3.0 switching performance metrics, validated pin-level control behavior (ENH/ONH), package-aware layout guidance for DHX2QFN14, and direct alternative comparisons for high-speed differential signal path selection.

Technical Context

The CBTL02GP023 implements a dual-differential-channel (A0/A1 and B0/B1) SPST architecture with independent ENH (global power enable) and ONH (switch state control) inputs. Its patent-pending analog pass-gate design supports rail-to-rail input voltage (0 V to VDD) across all I/O pins and maintains < −15 dB return loss at 2.5 GHz.

Switch operation is defined by two-tiered control: ENH = LOW disables the entire chip (12 µA sleep current), while ONH toggles channel conduction state under active power (500 µA max). Off-isolation reaches −16 dB at 2.5 GHz when ENH = HIGH and ONH = LOW, and intra-pair skew is tightly controlled at 6 ps (typ).

FAQ

What is the maximum data rate supported by the CBTL02GP023?

The CBTL02GP023 supports up to 5 Gbps, fully compliant with USB3.0 SuperSpeed signaling requirements. This is confirmed by its −1.5 dB insertion loss at 2.5 GHz and 7 GHz bandwidth specification, which ensures reliable transmission of the fundamental and critical harmonics of 5 Gbps NRZ data streams. The CBTL02GP023 has been characterized and validated for use in certified USB3.0 dongle and plug applications.

Does the CBTL02GP023 require external level shifters when interfacing with USB2.0 signals?

No, the CBTL02GP023 does not require external level shifters for USB2.0 signal interfacing. Its rail-to-rail input voltage capability (0 V to VDD) and common-mode input range (0 V to VDD) allow direct connection to 3.3 V USB2.0 D+/D− lines while operating from a 2.7–3.5 V supply. This feature is explicitly documented in the "Features and benefits" section and verified in Table 7 (VI limits) and Table 9 (VIC range) of the CBTL02GP023 datasheet.

How does the ENH pin function in the CBTL02GP023?

The ENH pin is the global enable control for the CBTL02GP023. When driven LOW, it places the entire device into a 12 µA sleep mode with all I/O pins in high-impedance state-critical for power-sensitive dongles. When HIGH, the device powers up and responds to ONH commands. This two-stage control (ENH + ONH) enables flexible power management strategies not found in simpler single-control switches, and is detailed in Table 5 of the CBTL02GP023 datasheet.

What package type is used for the CBTL02GP023HOZ variant?

The CBTL02GP023HOZ uses the DHX2QFN14 package: a 14-terminal, super-thin quad flat no-lead package measuring 1.5 mm × 2.1 mm × 0.32 mm with 0.4 mm pitch and an exposed center ground pad (SOT1458-1). This package is specified in Table 1 of the CBTL02GP023 datasheet and is optimized for high-density USB interface PCB layouts requiring minimal board area and excellent thermal performance.

Can the CBTL02GP023 be used for non-USB applications?

Yes, the CBTL02GP023 can be used for non-USB applications. Its 5 Gbps capability, 7 GHz bandwidth, low skew (6 ps typ), and rail-to-rail I/O make it suitable for general-purpose high-speed differential signal routing-including PCIe Gen1/Gen2, SATA, and custom LVDS-based protocols-provided signal swing and common-mode ranges fall within its 0 V to VDD specification. The datasheet explicitly states it "can be used as a general purpose 5 Gbps rail-to-rail low insertion loss switch chip in other applications."
