DVI, HDMI Extended Reach Equalizer with Retimer and
Output De-Emphasis
General Description
The DS22EV5110 is a 6.75 Gbps (3 x 2.25 Gbps) extended
reach equalizer optimized for DVI™and HDMI™ cable exten-
sion applications with a high performance re-clocking feature.
It 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 2.25 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 over DVI v1.0,
and HDMI v1.3a data rates up to 2.25 Gbps for each data
channel. The device incorporates a configurable receive
equalizer with a clock and data recovery (CDR) circuit on each
data channel. The clock channel feeds a high-perfromance
phase locked loop (PLL) that regenerates a low jitter output
clock for data recovery, enabling the extended reach of driv-
ing capability feature for repeater application.
The DS22EV5110 equalizes greater than 25 meters 28 AWG
of HDMI cable, enabling 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. Obtaining total jitter is 0.09 UI or less over the supported
data rates. This extremely low level of output jitter provides
system designers with extra margin and flexibility when work-
ing with stringent timing budgets. It is ideal for the DVI and
HDMI source and repeater applications.
The transmitter supports configurable transmit de-emphasis
so the output can be optimized for driving additional lengths
of cables or FR4 traces.
