DESCRIPTION
The DS22EV5110 is a 6.75 Gbps (3 x 2.25 Gbps)
extended reach equalizer optimized for DVI™ and
HDMI™ cable extension 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-performance phase locked loop (PLL) that
regenerates a low jitter output clock for data recovery,
enabling the extended reach of driving 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 working 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.
