Product details

12 Gbps re-driver for DP++ 1.1 to HDMI 2.1

The Texas Instruments TDP1204RNQR is a 4-channel differential buffer and re-driver designed to bridge DisplayPort++ 1.1 sources to HDMI 2.1 sinks at up to 12 Gbps per lane. It applies input equalization and output pre-emphasis to recover signal integrity over longer PCB traces or cable runs — effectively cleaning up the eye diagram before the sink's receiver. The 220 ps propagation delay is tight enough to stay within link timing budgets for 4K and 8K video paths. Supply voltage sits in the 3.135 V to 3.465 V range, and the quiescent draw of 16 µA keeps the thermal footprint low in dense layouts.

Signal conditioning — why it matters for the BOM

The input equalization and output pre-emphasis recover signal integrity over long traces or cables at 12 Gbps.

Frequently asked questions

Does the TDP1204RNQR support HDMI 2.1 data rates?

Yes, it handles 12 Gbps per lane, which is the full HDMI 2.1 data rate for a single lane. The part is specified for DisplayPort 1.1 to HDMI 2.1 conversion.

What is the closest functional second-source to the TDP1204RNQR?

The TUSB1142RNQR is a 10 Gbps re-driver in a similar 40-WQFN package, but it targets USB 3.2 applications and lacks the HDMI/DisplayPort-specific equalization profile. It is not a pin-compatible drop-in for this signal chain.
