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.
