AI summary

DS90UB949TRGCTQ1 is a Texas Instruments automotive HDMI-to-FPD-Link III serializer for carrying up to 1080p60 or WUXGA 24-bit video over one or two FPD-Link III links.

Best for

Automotive HDMI display transport
1080p60 display links
Systems needing FPD-Link III control-channel support

Avoid if

The display endpoint does not use a supported FPD-Link III deserializer
A single link must carry TMDS clocks above 96 MHz
The system cannot provide the required 1.1 V and 1.8 V rails

Check before use

Verify deserializer compatibility and configured link mode
Use 33 nF AC-coupling capacitors with supported 94x deserializers
Disable FPD3 PLL reset on frequency change by setting register 0x5B bit 5 to 0 after configuration
