Pericom Semiconductor’s PI3DPX1203 is DisplayPort compliant with 8 Gbps link speed, single differential channel linear ReDriver, and link training transparent mode. Since DisplayPort source and sink-side devices are unaware of the linear ReDriver, they never generate AUX link training transactions and pass through all the AUX transactions between source and sink-side devices.
The PI3DPX1203 provides programmable input equalization, linear swing, and flat gain control to optimize output over a variety of physical mediums by reducing inter-symbol interference. The integrated linear equalization circuitry provides flexibility with signal integrity of the signal before and after the ReDriver. A low-level input signal detection and output squelch function is provided.
| Features |
|
|
- DisplayPort standard 1.3 compliant linear ReDriver
- Supports flexible placement for active cable, sink, and source side
- Ideal for USB Type-CTM sink and source-side application with PD controllers
- Transparent DisplayPort link training; no need for AUX link training listener circuits
- Low latency transparent for the DisplayPort link training allow for sink-side application
- Linear input equalization increases link margin for systems implementing decision feedback routing equalizers (DFE)
