3 说明

SNx5DP159 器件是一款双模[1] DisplayPort 转最小化传输差分信号 (TMDS) 重定时器,支持数字视频接口 (DVI) 1.0 以及高清多媒体接口 (HDMI) 1.4b 和 2.0 输出信号。SNx5DP159 器件通过 DDC 链路或 AUX 通道支持双模标准版本 1.1 的 1 类和 2 类应用。SNx5DP159 器件的每条数据信道支持的数据速率高达 6Gbps,可支持超高清 (4K × 2K/60Hz) 8 位彩色高分辨率视频和 1080p 16 位色深的高清电视 (1920 × 1080/60Hz)。SNx5DP159 器件在数据速率低于 1Gbps 时可自动配置为转接驱动器,在超过该数据速率后可自动配置为重定时器。此特性可通过 I2C[4] 编程来关闭。

为确保信号完整性,SNx5DP159 器件实现了多个 特性。SNx5DP159 接收器支持自适应和固定均衡,以便消除电路板走线或电缆因带宽受限而引起的码间串扰 (ISI) 抖动或损耗。用作重定时器时,内置的时钟数据恢复 (CDR) 功能可清除输入端高频和视频源的随机抖动。发送器提供多种 功能 不仅有利于达到合规要求,还能够减少系统设计问题,例如去加重功能可补偿驱动长电缆或高损耗电路板走线时的衰减。SNx5DP159 器件还包含使用 Vsadj 引脚上的外部电阻器实现的 TMDS 输出幅值调节功能,以及源端选择功能和输出转换速率控制功能。器件的运行和配置可通过引脚设置或 I2C[4] 编程。

SNx5DP159 器件采用多种方法来进行电源管理和降低有功功率。
