Description

The NB7NQ621MMUTWG is a high-performance, quad-channel linear redriver and level shifter from onsemi, designed to enhance signal integrity in high-speed digital video interfaces such as HDMI® 2.1 and DisplayPort™ 1.4a. It supports data rates up to 12 Gbps, making it suitable for applications requiring high-bandwidth video transmission.

Key Specifications

• Functionality: Dual-mode DisplayPort (DP++) linear redriver and level shifter

• Data Rate: Supports up to 12 Gbps (HDMI 2.1 FRL), 8.1 Gbps (DisplayPort HBR3), and 6 Gbps (TMDS)

• Voltage Supply: 3.3 V (±5%)

• Channels: 4

• Equalization: Up to 15 dB at 6 GHz

• Control Interface: I²C programmable with support for fast-mode transfer up to 400 kbps

• Operating Temperature Range: −40°C to +85°C

• Package: 38-pin X2QFN (4.05 mm × 4.5 mm)

Features

• Signal Integrity Enhancement: Compensates for signal degradation due to PCB traces, cables, and inter-symbol interference by providing adjustable equalization and flat gain settings.

• Transparency: Being a linear redriver, it is inherently transparent to link training signals, simplifying system integration and software development.

• Flexible Coupling: Supports both AC and DC coupling at input and output, potentially eliminating the need for additional level shifter components.

• I²C Programmability: Allows for convenient adjustments to operation mode, channel power-down, flat gain, equalization, and output swing settings.

• Hot Plug Detection: Supports 5 V to 3.3 V level shifting for HDMI hot plug detection pins.

• AUX Channel Monitoring: Supports DisplayPort AUX channel monitoring for lane count and power state.

• Development Tools: Accompanied by a graphical user interface (GUI) to assist system designers in optimizing settings and generating register configurations.

Applications

• HDMI 2.1 and DisplayPort 1.4a interfaces

• Gaming consoles and graphics cards

• Set-top boxes and Blu-ray players

• Desktops, notebooks, and docking stations
