国产芯片LT9721：可实现MIPI/HDMI到DP转换的芯片描述

1.产品描述
LontiumLT9721是MIPI/HDMI到DP转换器，带有内部Type-C交替模式开关和PD控制器。
对于MIPIDSI®输入，LT9721具有单端口MIPIDSI接收器，具有1个时钟通道和4个数据通道，每个数据通道最大1.5Gbps，最大输入带宽为6Gbps。转换器对输入的18/24位RGB数据包进行解码，并将格式化的视频数据流转换为4路DP1.2兼容输出，支持RBR（1.62Gbps），HBR（2.7Gbps）和HBR2（5.4Gbps）链路速度。内置可选的SSC功能可降低EMI对系统应用的影响。
对于HDMI输入，LT9721具有1个时钟通道的HDMI1.4接收器和3个数据通道，每个数据通道最大3.4Gbps，最大输入带宽为10.2Gbps，RGB格式的分辨率高达4Kx2K@30Hz，60Hz为4Kx2KYUV420格式。该转换器还集成了DDC控制器并支持HDCP1.4。
为了适应最新的USBType-C生态系统，LT9721集成了由CC逻辑和PD管理单元控制的高性能双向无源差分开关，以降低移动系统设计复杂性和BOM成本。开关功能符合USBType-C标准的VESADP备用模式。
LT9721采用先进的CMOS工艺制造，采用小尺寸5mmx5mmBGA81（LT9721-B81）和7.5mmx7.5mmQFN64（LT9721-Q64）封装。该封装符合RoHS标准，额定工作温度范围为-40°C至+85°C。

1. Product description
The LontiumLT9721 is a MIPI/HDMI to DP converter with an internal Type-C alternating mode switch and PD controller.

For MIPIDSI® inputs, the LT9721 features a single-port MIPIDSI receiver with 1 clock channel and 4 data channels, each with a maximum of 1.5Gbps and a maximum input bandwidth of 6Gbps. The converter decodes the input 18/24-bit RGB packets and converts the formatted video data stream into 4 DP1.2-compatible outputs, supporting RBR (1.62Gbps), HBR (2.7Gbps), and HBR2 (5.4Gbps) link speeds. The built-in optional SSC function reduces the impact of EMI on system applications.

For HDMI inputs, the LT9721 features an HDMI1.4 receiver with 1 clock channel and 3 data channels, each with a maximum of 3.4Gbps and a maximum input bandwidth of 10.2Gbps, resolution up to 4Kx2K@30Hz in RGB format and 4Kx2KYUV420 in 60Hz. The converter also integrates a DDC controller and supports HDCP1.4.

To accommodate the latest USBType-C ecosystem, the LT9721 integrates a high-performance bidirectional passive differential switch controlled by CC logic and PD management units to reduce mobile system design complexity and BOM costs. The switch function complies with the VESADP standby mode of the USBType-C standard.

The LT9721 is manufactured using an advanced CMOS process and is available in a small 5mmx5mmBGA81 (LT9721-B81) and 7.5mmx7.5mmQFN64 (LT9721-Q64) package. The package is RoHS compliant and has a rated operating temperature range of -40°C to +85°C.
