The SNx5DP159 device is a dual mode Display Port to transition-minimized differential signal (TMDS) retimer supporting digital video interface (DVI) 1.0 and high-definition multimedia interface (HDMI) 1.4b and 2.0 output signals. The SNx5DP159 device supports the dual mode standard version 1.1 type 1 and type 2 through the DDC link or AUX channel. The SNx5DP159 device supports data rate up to 6 Gbps per data lane to support Ultra HD (4K × 2K / 60 Hz) 8-bits per color high-resolution video and HDTV with 16-bit color depth at 1080p (1920 × 1080 / 60 Hz). The SNx5DP159 device can automatically configure itself as a re-driver at data rates <1 Gbps, or as a retimer at more than this data rate. This feature can be turned off through I2C programming.
For signal integrity, the SNx5DP159 device implements several features. The SNx5DP159 receiver supports both adaptive and fixed equalization to clean up inter-symbol interference (ISI) jitter or loss from the bandwidth-limited board traces or cables. When working as a retimer, the embedded clock data recovery (CDR) cleans up the input high frequency and random jitter from video source. The transmitter provides several features for passing compliance and reducing system-level design issues like de-emphasis, which compensates for the attenuation when driving long cables or high-loss board traces. The SNx5DP159 device also includes TMDS output amplitude adjust using an external resistor on the Vsadj pin, source termination selection, and output slew rate control. Device operation and configuration can be programmed by pin strapping or I2C.
The SNx5DP159 device implements several methods for power management and active power reduction.
The SNx5DP159 receiver uses several methods to determine whether the application supports HDMI1.4b or HDMI2.0 data rates. The SNx5DP159 receiver comes in two packages; 40-pin RSB supporting the space-constrained applications and 48-pin RGZ version supporting the full feature set for Display Port dual-mode standard version 1.1 in applications such as dongles.
