3 Description
The SNx5DP149 device is a dual mode[1]
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 I²C[4] programming.
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[4].
The SNx5DP149 device implements several methods
for power management and active power reduction.
