Overview
The TDP158RSBR from Texas Instruments is a high-performance, AC-coupled HDMI signal level shifter designed to support the transition-minimized differential signal (TMDS) and DisplayPort dual-mode standards. This device is capable of handling data rates up to 6 Gbps, making it suitable for high-resolution video applications such as 4K at 60 Hz and WUXGA with 16-bit color depth. It is compatible with HDMI 2.0b electrical parameters and supports DisplayPort dual-mode standard version 1.1. The TDP158RSBR is packaged in a 40-pin, 0.4mm pitch, 5mm × 5mm WQFN package, which is pin-compatible with the SN75DP159RSB retimer.
