Description
The DS34RT5110 is a 10.2 Gbps (3 x 3.4 Gbps) high performance re-clocking device that supports 3 Transition Minimized Differential
Signaling (TMDS®) data channels and a single clock channel over DVI™ v1.0, and HDMI™ v1.3a data rates up to 3.4 Gbps for each
data channel. The device incorporates a configurable receive equalizer, a clock and data recovery (CDR) circuit and a de-emphasis
driver on each data channel. The clock channel feeds a high-performance phase-locked loop (PLL) that regenerates a low jitter
output clock for data recovery.
The DS34RT5110 equalizes and retimes greater than 25 meters 28 AWG of HDMI cable for 1080p resolution with 12 bit deep color
depth (2.25 Gbps), to a low jitter version of the clock and data signal outputs, reducing both deterministic and random jitter.
Several devices can be cascaded for long links without degrading signal fidelity. Obtaining total jitter is 0.09 UI or less
over the supported data rates. This low level of output jitter provides system designers with extra margin and flexibility
when working with stringent timing budgets.
The transmitter supports configurable transmit de-emphasis so the output can be optimized for driving additional lengths of
cables or FR4 traces.
The DS34RT5110-EVKC CAT5 Cable Extender Demo Kit provides a complete HDMI system extension solution with cost effective CAT5 cables, using Nationals DS34RT5110 - a DVI, HDMI Retimer with Input Equalization and Output De-Emphasis.
The kit consists of following boards for different application needs:
a DS34RT5110 driver board with HDMI-in and RJ45-out connectors
Board ID: 551600199-034
a DS34RT5110 repeat board with RJ45-in and RJ45-out connectors
Board ID: 551600199-014
a DS34RT5110 receiver board with RJ45-in and HDMI-out connectors
Board ID: 551600199-024
a passive adapter board with RJ-45 and HDMI connectors
Board ID 980013178
The DS34RT5110 driver board has one HDMI female receptacle connector as the input and two RJ45 jacks as the outputs.
The DS34RT5110 repeater board has two RJ45 jacks as the inputs and two RJ45 jacks as the outputs.
The DS34RT5110 receiver board has two RJ45 jacks as the inputs and one HDMI female receptacle connector as the output.
The passive adapter board has two RJ45 jacks and one HDMI female receptacle connector, can be as either the input or the output.
The DS34RT5110 on the boards equalizes and retimes the long reach HDMI or CAT5 cable at the input, then sends out the low jitter TMDS signal to the HDMI or CAT5 cable through output.
All the TMDS signals are connected through one RJ45 jack between two boards.
The DDC signals are connected through an I2C buffer; the Hot Plug, 5V Power and 5V Ground are directly connected between the connectors, making this demo kit HDCP compliant.
A 3.3V VCC 1-pin header and a GND 1-pin header are used for the power supply for the DS34RT5110 boards.
Alternately, an AC/DC power adapter (>800mA) is required for each driver or receiver board of the evaluation kit to provide 5V DC voltage for easy portability. A 1.8mm DC Power Jack is used to connect the AC/DC Power Adapter. National?s LP3965, a 3.3V, 1500mA, Fast, Ultra Low Dropout Linear Regulator, converts the 5V power supply voltage to a 3.3V power supply voltage that powers the DS34RT5110.
Board Errata Information
This set of demo boards are designed for either AC or DC coupled application.
The current boards in this kit are assembled for the DC coupled application. For proper demo with this DCcoupled setup, the GND jumpers (ic. J26, J30, and J34) on these boards have to be connected together, in order to share the same common ground on all boards.
This approach is not required if AC coupled application is used.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
