SDI, SDI
The CYV15G0101EQ accepts single-ended or differential
serial video data streams over 75
coaxial cable. It is recom-
mended to AC-couple the SDI, SDI inputs as they are inter-
nally biased to 1.2V.
SDO, SDO
The CYV15G0101EQ has differential serial output interface
drivers that use current mode logic [CML] drivers to provide
source matching for the transmission line. These outputs can
be either AC coupled or DC coupled to the HOTLink II SerDes
device.
CLI
Cable Length Indicator (CLI) is an analog output that gives an
output voltage proportional to the cable length being
equalized. CLI gives an approximation of the length of cable
at the differential serial inputs (SDI, SDI). CLI works at high
definition (HD) data rates as well as standard definition (SD)
data rates. The graph in
Figure 2
illustrates the CLI output
voltage at various Belden 1694A cable lengths. With an
increase in cable length, CLI output voltage decreases.
MCLADJ
Maximum Cable Length Adjust (MCLADJ) sets the approx-
imate maximum amount of cable to be equalized. When the
maximum cable length set by MCLADJ is reached, the outputs
are muted. MCLADJ works at SD as well HD data rates.
If the MCLADJ voltage is greater than the CLI output voltage,
the equalizer serial differential outputs (SDO, SDO) are muted.
If the MCLADJ voltage is less than CLI voltage, then the
equalizer’s differential serial outputs (SDO, SDO) are not
muted and the incoming data stream is equalized. The graph
in
Figure 1
illustrates the voltage needed at MCLADJ input to
equalize various Belden 1694A cable lengths for SD and HD
data rates. The MCLADJ pin can be left unconnected in appli-
cations that do not require muting of the outputs.
CD/MUTE
Carrier Detect/MUTE (CD/MUTE) is a bidirectional pin that
provides an indication of the signal being present at the
equalizer’s input, or it controls the muting of the equalizer’s
output. The (CD/MUTE) operates for both HD and SD data
rates.
If CD/MUTE is used as an output and the incoming data
stream is not present, the voltage at the CD/MUTE output will
be greater than 2.9V. If CD/MUTE is used as an output and the
incoming data stream is present, then the voltage at the
CD/MUTE output will be less than 0.8V.
If CD/MUTE is used as an input and is tied to ground, the
equalizer serial outputs are not muted and the MCLADJ
setting is overwritten. If the CD/MUTE is used as an input and
is tied to V
CC
, then the equalizer serial outputs are muted and
the MCLADJ setting is overwritten.
When an invalid signal or a signal transmitted with a launch
amplitude of less than 500 mV at HD data-rates is received,
the equalizer’s serial outputs are muted and the MCLADJ
setting is overwritten.
BYPASS
The CYV15G0101EQ has a bypass mode that allows the user
to bypass the equalizer’s equalization and DC restoration
functions. When the Bypass mode is tied to V
CC
, the signal
presented at the equalizer’s differential serial inputs (SDI, SDI)
is routed to the equalizer’s differential serial outputs (SDO,
SDO) without performing equalization.
When BYPASS is tied to GND, the incoming video data stream
is equalized and presented at the equalizer‘s differential serial
outputs (SDO, SDO).
In equalizer bypass mode, CD/MUTE is not functional.
AGC
A capacitor of 1
μ
F should be placed between the AGC± pins
of the CYV15G0101EQ equalizer.
