“…M EETING the ever-increasing demand for higher resolution, color depth, and refresh rate TVs requires high-throughput display driver integrated circuits (DDIs). A DDI receives high-speed data from the timing controller (TCON) and drives it to the pixel drivers [1]- [3]. In a typical 4K (UHD) TV, the throughput for each DDI is 3 Gb/s and is expected to increase to 5.2 Gb/s for the next-generation 8K (Quad-UHD) TVs.…”

This article presents a high-speed receiver for nextgeneration 8K ultra-high-definition TVs. The receiver supports error-free communication between the timing controller and the display driver integrated circuits (DDIs) across various channels. Because the receiver must be co-integrated with pixel drivers in the DDI, it must be implemented in a process with high-voltage devices, which poses significant challenges in achieving beyond 5-Gb/s operation. We propose techniques for overcoming such process-induced speed limitations. They include a level-shifting passive continuous-time linear equalizer (CTLE), an active CTLE with extended bandwidth using a negative capacitor, a speculative decision feedback equalizer with a down-sampled edge-sampling path, and a low-dropout regulator with parallel error amplifiers to achieve all-band power supply rejection. A reference-less clock and data recovery circuit with a new frequency detector is also described. Fabricated in a 180-nm CMOS process, the prototype receiver operates at 5.2 Gb/s and can compensate up to 29-dB channel loss while consuming 120 mA from a 1.8-V supply.

“…Introduction: As high-resolution display systems require the massive transmission of graphic data, data rates of high-speed interfaces for display SoCs continue to grow. For example, intra-panel interfaces to support 5-10 Gb/s per-lane data rates for 8K displays and 15+Gb/s for next-generation ones [1][2][3]. However, the channel bandwidths of such display systems are severely limited due to loss and reflections from long PCB traces and FPC (Flexible Printed Circuit) structures.…”

This paper describes a channel-loss-tolerant 16.7-Gb/s PAM-4 transmitter with feed-forward equalization (FFE) for display interfaces. The proposed transmitter adopts full transition avoidance (FTA) coding in combination with the 2-tap FFE to enhance the worst-case horizontal eye-opening in the presence of inter-symbol interference (ISI) and shunt switches to reduce power consumption. The transmitter test chip was fabricated in a 28-nm CMOS process and occupied 0.04 mm2. The design achieved 16.7-Gb/s (corresponding to 10 Gbaud/s) with a 0.20x wider horizontal eye-opening for a >7.2 dB loss channel while consuming 107.6mW (corresponding to 6.4 pJ/bit) from the 1.2-V supply.
