PTN3944 is a high-performance multi-channel (x4) linear equalizer that is optimized for PCIe 4.0, UPI and similar high-speed interfaces. PTN3944 addresses high-speed signal quality enhancement requirements for 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 enable channel extension by reducing Inter-Symbol Interference (ISI). The equalizer supports use across a variety of channel conditions. PTN3944 supports entering into deep standby state using an I2C register write.
PTN3944 is powered from a 1.8 V supply. It is available in a small high performance HWFLGA36 package.
