DVI, HDMI Retimer with Input Equalization and Output De-
Emphasis
General Description
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.
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.
The transmitter supports configurable transmit de-emphasis
so the output can be optimized for driving additional lengths
of cables or FR4 traces.
