PTN38003A is a high-performance USB3.2 and DP1.4 combination linear redriver that is optimized for USB Type-C downstream facing (DFP) or upstream facing (UFP) ports. PTN38003A is a USB Type-C high-speed linear redriver used to meet signal quality enhancement requirements in platforms that support the USB 3.2 Gen2 and VESA DisplayPort 1.4 over USB Type-C Alt Mode Standards. The device provides programmable linear equalization, output swing linearity control by pin strapping or I2C control to improve signal integrity and enable channel extension by reducing inter-symbol interference (ISI). This device also monitors sideband signals in DP mode to optimize the configuration, power saving mode and performance.
For USB operation, PTN38003A has built-in advanced power management capability that enables significant power saving under USB3.2 low power modes (U2/U3). It detects LFPS (Low Frequency Periodic Signaling)/LBPM (LFPS Based PWM Message) signaling to configure the operation (USB3.2 Gen 1/Gen 2 and x1/x2) and link electrical conditions and it activates/deactivates internal circuitry and logic dynamically. The device performs these actions without host software intervention to conserve power.
For DisplayPort (DP) operation, PTN38003A monitors the AUX transactions and adjusts the DisplayPort channel setting during DP Link initialization and training. PTN38003A is powered from a 1.8 V supply. It is available in a small high performance HWFLGA36 package
