3.3 V Dual-Mode HDMI 2.1®, DisplayPort™ 1.4a and DisplayPort™ (DP++) 12 Gbps Level Shifter/ Linear Redriver
Active
概览
The NB7NQ621M is a 3.3 V Dual−Mode DisplayPort (DP++) quad−channel linear redriver supporting HDMI® 2.1 Fixed Rate Link (FRL) up to 12 Gbps, TMDS up to 6 Gbps, and DisplayPort v1.4a Main Link (ML) up to 8.1 Gbps (HBR3). Signal integrity degrades from PCB traces, transmission cables, and inter−symbol interference (ISI). The NB7NQ621M compensates for these losses by engaging varying levels of user selectable flat gain and equalization to create the best eye opening for the outgoing data signals. The NB7NQ621M is a linear redriver and is inherently transparent to link training signals resulting in shorter system integration and software development cycles. The redriver input and output signals may be either AC or DC coupled, which can eliminate the need for additional level shifter components from the data channels. The NB7NQ621M is equipped with I2C programmability for convenient adjustments to operation mode, channel power down, flat gain, equalization, and output swing settings. It supports 5V to 3.3V level shifting for HDMI hot plug detection pins and supports DisplayPort AUX channel monitoring for lane count and power state. NB7NQ621M’s supplementary graphical user interface (GUI) was developed to help system designers optimize their system for the best settings. After optimization, the GUI can generate the register values and register settings in order to simplify software development.
