Other Parts Discussed in Thread: DS90UB921-Q1,

Hello TI Team,

We are planning to use the DS90UB921-Q1 serializer with the DS90UB948-Q1 deserializer for the following display interface:

RGB Parallel Input
→ DS90UB921-Q1
→ FPD-Link III
→ DS90UB948-Q1
→ Dual LVDS/OpenLDI Display

The target display requires dual-channel LVDS (8 LVDS data pairs).

Could you please confirm:

* Compatibility and feasibility of this serializer/deserializer pair
* Any limitations on pixel clock/resolution
* Key hardware/layout design considerations for this implementation

Please also share any relevant reference design or application note for this pair.

Regards,

Jawakar K

Hi Jawakar,

These devices are compatible with each other.

* Any limitations on pixel clock/resolution

When the 948 is paired with the 921 the PCLK frrequency range is 25MHz - 96MHz.

* Key hardware/layout design considerations for this implementation

The datasheets provide a detailed layout considerations and power up sequence requirements.
