PTN36242LBS,518

Signal Buffers, Repeaters, Splitters Overview

The PTN36242L is a dual-port SuperSpeed USB 3.0 redriver IC designed to enhance signal quality through receive equalization and transmit de-emphasis. It supports data signaling rates of 5 Gbit/s across four channels (two ports). The device operates from a 3.3 V supply with typical active power consumption of 743 mW (225 mA) at full swing and 6 dB equalization. Power-saving states include 60 mW in U2/U3 modes, 26 mW when no connection is detected, and 0.5 mW in deep power-saving mode. It features selectable equalization gains (3, 6, 7.5, or 9 dB) and de-emphasis levels (-3.5, 0, -5, or -7 dB). The component is housed in an HVQFN32 package measuring 3 mm x 6 mm x 0.85 mm.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix to confirm packing method and marking variations. The PTN36242LBS,518 variant utilizes a 16 mm carrier tape reel. Ensure compatibility with the required output swing settings by checking the external resistor configuration on the OS pin. Confirm that the HVQFN32 package dimensions align with the PCB footprint requirements for thermal relief and electrical grounding.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when signal integrity degradation due to PCB trace length or cable loss is a concern in USB 3.0 designs. The device allows per-channel adjustment of equalization gain and de-emphasis to match specific channel characteristics. Consider the power budget if operating in continuous active mode versus leveraging the automatic power-saving states triggered by USB link conditions. Ensure the system design accommodates the 3.3 V supply requirement and the specific ESD protection ratings for high-speed pins.

Signal Buffers, Repeaters, Splitters Part Context

The PTN36242L belongs to NXP's SuperSpeed USB 3.0 redriver family, which includes single-channel variants like the PTN36221A and other dual-port models. These components are engineered to bridge the gap between USB controllers and connectors, addressing signal attenuation issues inherent in high-speed serial interfaces. The dual-port design distinguishes it from single-channel redrivers, offering integrated signal conditioning for multiple peripheral connections within a compact form factor.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Publicly confirmed substitute part numbers include the PTN36241B and PTN36242LBS/S900. Verify pinout compatibility and functional equivalence regarding equalization and de-emphasis configurations before substitution.
