The SNx5DP159 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) 1.4band 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
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: a 40-pin
RSB supporting space-constrained applications and a 48-pin RGZ version supporting the full feature
set for DisplayPort dual-mode standard version 1.1 in applications such as dongles.
The SN75DP159 device is characterized
for an industrial operational temperature range from –40°C to 85°C.
The SN65DP159 device is characterized for an extended commercial operational
temperature range from 0°C to 85°C.
