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.
