PTN36221AHXHP

Signal Buffers, Repeaters, Splitters Overview

The PTN36221AHXHP is a single-channel SuperSpeed USB 3.0 redriver designed to enhance signal quality through receive equalization and transmit de-emphasis. It supports data signaling rates up to 5 Gbit/s and operates on a 1.8 V supply. The device features adjustable receive equalization (3 dB, 6 dB, or 9 dB), selectable transmit de-emphasis (-3.5 dB default, -6 dB max), and output swing control (900 mV to 1100 mV). It includes integrated termination resistors for impedance matching and automatic receiver termination detection. Power consumption is 97 mW in active mode, dropping to 5 mW in U2/U3 states and 18 µW in deep power-saving mode. It is housed in an X2QFN12 package measuring 1.6 mm x 1.6 mm x 0.35 mm with a 0.4 mm pitch.

Signal Buffers, Repeaters, Splitters Feature Summary

• Performs receive equalization to recover from inter-symbol interference and high-frequency losses.
• Provides transmit de-emphasis and output swing adjustment for pre-compensation suited to channel conditions.
• Integrates termination resistors for impedance matching on both transmit and receive paths.
• Supports low-power modes including U2/U3 and deep power-saving states without host software intervention.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the ordering part number PTN36221AHXHP corresponds to the X2QFN12 package in the 13-inch reel packing method. Confirm the ambient temperature range is -40 °C to +85 °C. Ensure the 1.8 V supply voltage specification matches the system design requirements. Check for compliance with SuperSpeed USB 3.0 standards and ESD ratings of 8 kV HBM and 1 kV CDM for the data path.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when signal integrity enhancement is required for single-channel USB 3.0 links at 5 Gbit/s. Consider its adjustable equalization and de-emphasis settings to compensate for PCB trace and cable channel losses. Evaluate its low power consumption benefits for mobile and portable applications. Ensure the system supports the 1.8 V supply voltage and utilizes the X2QFN12 package footprint.

Signal Buffers, Repeaters, Splitters FAQ

How does the PTN36221A handle power management?

The device implements an advanced power management scheme that relies on bus electrical conditions to enter power-saving states (U2/U3, no connection) or deep power-saving mode (EN LOW) without host software intervention.

What are the configurable settings for receive equalization?

Receive equalization can be set to 3 dB (LOW), 6 dB (Open/Default), or 9 dB (HIGH) via the EQ pin to recover from inter-symbol interference and high-frequency losses.

What is the default transmit de-emphasis setting?

The default transmit de-emphasis setting is -3.5 dB (Open state), with options for 0 dB (LOW) and -6 dB (HIGH).
