9‐5L: Late‐News Paper: 6Gb/s Ultra Definition Display Interface (UDDI) for Large‐size 8K Displays

A 6Gb/s per lane ultra-definition display interface (UDDI) system is presented to reduce the production cost and to improve the form-factor of Quad-UHD TV panels. The receiver (RX) is implemented in a 0.18um Source IC process. The transmitter (TX) is fabricated in a low-leakage 65nm process for integration with a Timing Controller (TCON) ASIC. The analog front-end of the receiver is equipped with a continuous-time linear equalizer and a 5-tap decision feedback equalizer. Continuous calibration and adaptation engines in the receiver ensure reliable communication over an extended operation period. The transmitter employs 3-tap pre-emphasis for channel equalization and a dual-VCO LC PLL for low jitter transmission. System link layer employs a low-overhead error correction code to protect video data against random errors and to limit worst-case run-length. The system also deploys scrambling to reduce EMI. Noise-free video quality was achieved at 6Gb/s over 65” display Source PCBs and at 4Gb/s over 105” display Source PCBs. The UDDI system improves the highest existing intra-panel interface speed by nearly a factor of 2.
