Design Notes
- MS2132 targets HD 2.0 to USB 3.0 4K60 capture designs. Validate HD 2.0 signal integrity, USB 3.0 bandwidth, thermal margin, and host compatibility.
3840 x 2160 @ 60HzUSB output depends on MJPEG mode. For YUV422, RGB24, NV12, or other lower-compression formats, validate achievable resolution and frame rate against USB bandwidth and host performance.- HDCP 2.3 / 1.4 involves licensing and key-management requirements; products should comply with the applicable authorization rules.
- MCU customization, SID ambient lighting, PWM, and GPIO functions should be validated with the official SDK, firmware, and reference design.
