Cable TMDS Equalizer
The MAX3814 is useful in providing equalization for
cables losses at location ZZ, at the input DVI/HDMI
connector of the remote display. It can equalize cable
lengths of 15 meters of 26 AWG wire and 12 meters of
28 AWG wire. Again, the 200
Ω resistor placed at the
output of the MAX3814 absorbs reflections from the
imperfect termination of the ASIC or imperfect transmis-
sion-line interconnect.
Layout Considerations
The TMDS CML inputs are the most critical paths for
the MAX3814 and great care should be taken to mini-
mize discontinuities on these transmission lines
between the connector and the IC. Here are some sug-
gestions for maximizing the performance of the
MAX3814.
The data and clock inputs should be wired direct-
ly between the cable connector and IC without
stubs.
The 4-channel implementation treats all channels
identically. Input and output data channel designa-
tions are only a guide. Polarity assignments can be
swapped and channel paths can be interchanged.
An uninterrupted ground plane should be posi-
tioned beneath the high-speed I/Os.
Ground-path vias should be placed close to the
IC and the input/output interfaces to allow a return
current path to the IC and the DVI and HDMI
inputs.
Maintain a 100
Ω differential transmission line
impedance into and out of the MAX3814.
To minimize possible reflections, choose the
200
Ω back termination option. Place this resistor
as close to the MAX3814 as possible.
Use good high-frequency layout techniques and
multilayer boards with an uninterrupted ground
plane to minimize EMI and crosstalk. Refer to the
schematic and board layers of the MAX3814EVKIT.
