DS34RT5110
DVI, HDMI Retimer with Input Equalization and Output De-
Emphasis
General Description
Features
The DS34RT5110 is a 10.2 Gbps (3 x 3.4 Gbps) high perfor-
mance re-clocking device that supports 3 Transition Mini-
mized 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 in-
corporates 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.
Optimized for HDMI/DVI repeater applications
■
■
TMDS compatible inputs with configurable receive
equalization supporting data rates up to 3.4 Gbps
TMDS compatible outputs with configurable transmit de-
emphasis
■
Dedicated CDR on each data channel reduces jitter
transfer, enabling multiple devices to be cascaded without
impairing signal fidelity
■
Capable of multi-hop extension of HDMI/DVI applications
at data rates between 250 Mbps and 3.4 Gbps
■
The DS34RT5110 equalizes and retimes greater than 25 me-
ters 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 out-
put jitter provides system designers with extra margin and
flexibility when working with stringent timing budgets.
Resistor adjustable differential output voltage for AC
coupled Cat5e and Cat6 extension applications
2 equalizer settings for a wide range of cable reaches at
different data rates

■
Total Output Jitter of 0.10 UI at 3.4 Gbps
DVI 1.0 and HDMI v1.3a compatible TMDS source and
sink interface
The transmitter supports configurable transmit de-emphasis
so the output can be optimized for driving additional lengths
of cables or FR4 traces.
