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.
