说明

TMDS171 是一款数字视频接口 (DVI) 或高清多媒体接口 (HDMI) 重定时器。TMDS171 支持四条 TMDS 通道,音频返回通道 (SPDIF_IN/ARC_OUT)、热插拔检测 (HPD) 和数字显示控制 (DDC) 接口。TMDS171 支持高达 3.4Gbps 的信号传输速率,可实现最高分辨率达 4k2k30p 24 位/像素和高达 WUXGA 12 位色深或 1080p,并且具有较高的刷新率。TMDS171 在低于 1Gbps 的数据速率下会自动配置为重驱动器,而在高于该速率时会自动配置为重定时器。

TMDS171 支持双电源轨(VDD 为 1.2V,VCC 为 3.3V),有助于降低功耗。该器件采用多种电源管理方法来降低整体功耗。TMDS171x 通过 I2C 或引脚设置支持固定的 EQ 增益或自适应 EQ 控制,以补偿不同长度的输入电缆或电路板走线。
