背景

support 侧收到关于 瑞莎 4K HDMI IN 转 MIPI CSI-2 转接板(RK628H)的规格咨询,问题集中在两点:

  1. MIPI 输出单 lane 速率是多少?
  2. 转接板是 2-lane 还是 4-lane?2-lane 能出到多高分辨率?

现有文档只写了「1x 2-lane MIPI CSI;1x 4-lane MIPI CSI,最高输出 4K@30fps」,读者容易把 4K@30fps 误当成两个接口都适用;单 lane 速率文档中完全没有提及。

缺口位置

  • docs/accessories/display/hdmi-in-to-mipi-csi2/README.md(主要特性 + 产品规格表)
  • i18n/en/.../hdmi-in-to-mipi-csi2/README.md(对应英文页)

修复内容

  • 明确 4-lane(31-Pin)最高 4K@30fps(3840 x 2160)、2-lane(15-Pin)最高 2K@30fps(2560 x 1440)
  • 补充 MIPI D-PHY 单 lane 最高 1.3 Gbps

规格数值已由内部硬件/软件同事确认(RK628H 数据手册 Table 1-2 与实测口径一致)。中英文同步修改。

影响范围

仅该配件产品页的文字描述,不涉及代码、配置或其他文档;用于减少「4K@30fps 适用于所有 MIPI 接口」及「单 lane 速率未知」两类误读。

…to MIPI CSI-2 adapter

Add the per-lane data rate (up to 1.3 Gbps) and the 2-lane output
resolution limit (up to 2K@30fps, 2560x1440) to the adapter page, so the
two MIPI CSI-2 connectors are no longer described with a single 4-lane
4K@30fps figure.
