NXP Semiconductors PTN3944EVM-KIT Evaluation Board provides a demonstration and development platform for the PTN3944 Multi-Channel PCIe Gen 4 Linear Equalizer. The PTN3944 is optimized for PCIe 4.0, UPI, and similar high-speed interfaces. The PTN3944 addresses high-speed signal quality enhancement requirements for the implementation of PCIe and UPI interfaces. The device provides programmable linear equalization, output swing linearity control by pin strapping or I2C control to improve signal integrity, and enables channel extension by reducing Inter Symbol Interference (ISI). Using multiple components of the PTN3944 enables the redriving of PCIe signals to up to 16 devices installed in a PCIe slot.
NXP Semiconductors PTN3944EVM-KIT Evaluation Board is an Add-In Card (AIC) is designed for use in an available PCIe x16 slot on a PC or server computer. A CEM connector on the top of the Evaluation Board can be connected to a PCIe device. On the front of the Evaluation Board are four PTN3944 ICs that redrive PCIe signals from the motherboard side (from CPU/chipset) to the PCIe device. On the back of the Evaluation Board, another four PTN3944 ICs redrive PCIe signals from a PCIe device to the motherboard side (to CPU/chipset). The PTN3944 Equalizer ICs, output swing level, and flat gain settings can be configured through either onboard DIP switches or from the I2C bus controlled by a Graphic User Interface.
The PTN38007/PTN38003A/PTN3944 Software GUI provides a Graphic User Interface that enables users to monitor and change the PTN3944
registers.
