3 Description

The SN65DP141 is an asynchronous, protocolagnostic,

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.
