3 Description

The SN65DP141 is an asynchronous, protocol-agnostic, low latency, four-channel linear equalizer optimized for use up to 12 Gbps and compensates for losses due to board traces and cables.

The device is transparent to DisplayPort (DP) link training such a way that a DP source and a sink can perform effective link training overcoming traditional aux snooping re-drivers’ shortcomings. Additionally, the device is position independent. It can be placed inside source, cable or sink effectively providing a negative loss component to the overall link budget. Linear equalization inside SN65DP141 also increases link margin when used with a receiver implementing Decision Feedback Equalization (DFE).

SN65DP141 allows independent channel control for equalization, gain, dynamic range using both I2C and GPIO configurations.
