The SNx5DP149 device is a
dual mode DisplayPort to transition-minimized differential signal (TMDS)
retimer supporting digital video interface (DVI) 1.0 and high-definition multimedia interface
(HDMI) 1.4b output signals. The
SNx5DP149 device supports the dual
mode standard version 1.1 type 1 and type 2 through the DDC link. The SNx5DP149 device
supports data rate up to 3.4-Gbps
per data lane to support Ultra HD (4K × 2K / 30-Hz) 8-bits per color high-resolution video and HDTV with 16-bit color
depth at 1080p (1920 × 1080 / 60-Hz). The SNx5DP149 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
For signal integrity, the SNx5DP149 device implements several features. The SNx5DP149 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 SNx5DP149 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 SNx5DP149 device
implements several methods for power management and active power reduction.
The SNx5DP149 receiver comes in a 40-pin RSB supporting space-constrained applications.
The SN65DP149 device is
characterized for an industrial operational temperature range from –40°C to 85°C.
The SN75DP149 device is
characterized for an extended commercial operational temperature range from 0°C to 85°C.
