Overview
The SN75DP159RSBR is a dual-mode DisplayPort to HDMI retimer developed by Texas Instruments. This device supports the transition-minimized differential signal (TMDS) and is compatible with digital video interface (DVI) 1.0 and high-definition multimedia interface (HDMI) 1.4b and 2.0b output signals. It is designed to handle data rates up to 6 Gbps per data lane, making it suitable for Ultra HD (4K × 2K / 60-Hz) and HDTV with high color depth.
The SN75DP159RSBR can automatically configure itself as a re-driver at data rates below 1 Gbps or as a retimer at higher data rates, with this feature adjustable through I2C programming. The device is available in two packages: a 40-pin RSB for space-constrained applications and a 48-pin RGZ version for full feature support in applications like dongles.
