Typical Applications
(Continued)
CLC005 driver. Loss of Signal (LOS) is connected to MUTE
to latch outputs DO and DO in the absence of an input signal
to the equalizer.
Refer to the CLC012’s evaluation board layout for additional
suggestions.
National can supply most of the major components required
to design a transmission line repeater. Figure 11 shows a
typical repeater design using the CLC005, CLC012, and the
CLC016. The design functions supported by each chip are:
CLC005:
Cable connection chip
Boosts drive for transmission to next repeater or
final destinations
CLC012:
Receive serialized digital data from incoming
transmission lines
Equalizes the incoming data
CLC016:
Retimes the equalized data (improving jitter)
The CLC016 is a multi-rate data retiming PLL. The circuit
(Figure 11) will work at up to 4 different data rates with no ad-
ditional components or manual tuning.
DIGITAL VIDEO (SDV) ROUTERS
The CLC012 provides performance that complies with the
ITU-T G.703 standard for serial digital data transmission
over coaxial cable. One common application is in routers,
which provide a switching matrix for connecting source
equipment to destination equipment.
Figure 12shows a typical configuration for a router, including
equalizers, a crosspoint switch, data retimers, and cable
drivers. The CLC012 is used in its standard configuration in
this application, and automatically equalizes cable lengths
from zero meters to greater than 300 meters at 360 MHz
(see plots in
Typical Performance Characteristics
sec-
tion). The equalized outputs are connected to the differential
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 CLC005
ITU-T G.703 Cable Driver (with two amplitude-adjustable
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
CLC012 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
