Typical Applications
(Continued)
DIGITAL VIDEO (SDV) ROUTERS
The CLC014 provides performance that complies with the
SMPTE 259M standard for serial digital video (SDV) trans-
mission over coaxial cable. One common application is in
SDV routers, which provide a switching matrix for connecting
video source equipment (e.g., cameras) to destination equip-
ment (e.g., video tape recorders, monitors, etc.).
Figure 12shows a typical configuration for an SDV router, in-
cluding equalizers, a crosspoint switch, data retimers, and
cable drivers. The CLC014 is used in its standard configura-
tion in this application, and automatically equalizes cable
lengths from zero meters to greater than 300 meters at
360 MHz (see plots in
Typical Performance Characteris-
tics
section). The equalized outputs are connected to the dif-
ferential inputs of the crosspoint switch. The CLC016 Data
Retimer receives the data from the crosspoint and performs
the clock and data recovery functions, further reducing jitter.
Finally, the retimed data is driven into the coaxial cable by a
CLC006 Cable Driver (with two amplitude-adjustable out-
puts) or a CLC007 Cable Driver (with four outputs).
TWISTED PAIR DRIVER
A low-cost medium for transmitting data is twisted pair. Cat-
egory 5 UTP has an attenuation characteristic similar to
Belden 8281 coaxial cable but scaled in length: 120 meters
of Category 5 UTP is roughly equivalent to 300 meters of
Belden 8281 cable. When properly implemented, the
CLC014 will equalize data rates up to 625 Mbps over Cat-
egory 5 UTP. The maximum data rate depends upon the
cable length. A plot of Maximum Data Rate vs Cable Length
is found in the
Typical Performance Characteristics
sec-
tion for Belden 8281, and can be scaled as stated above to
estimate maximum cable lengths and data rates for UTP.
Category 5 UTP has a characteristic impedance of approxi-
mately 100
. The CLC006 in Figure 13 is used to drive the
twisted pair AC-coupled with a series 0.1 μF capacitor and a
50
resistor in each differential output. The CLC014 Adap-
tive Equalizer requires 800 mV
