Twisted Pair Termination
The schematic in Figure 20 illustrates a termination scheme
for 50
Ω
series termination and a 100
Ω
twisted pair cable.
Note RCM is the common mode termination to allow
measurement of V
CM
and should not be too small since it
loads the ISL59311; a little over a 100
Ω
is recommended for
RCM.
Video Transmission
The ISL59311 is a twisted pair differential line driver directed
at the transmission of Video Signals through cables up to
100 feet; however, as signal losses increase with
transmission line length the ISL59311 will need additional
support to equalize video signals along longer twisted pair
transmission lines. A full solution to accomplish this is the
SXGA Video Transmission System presented in the
ISL59311 Data Sheet. Note the inclusion of the EL9111 for
signal equalization of up to 1000ft of CAT-5 cable and
common mode extraction; see Data Sheet for additional
information on the EL9111.
Long Distance Video Transmission
The SXGA Video Transmission System makes it possible to
transmit Red, Green and Blue (RGB) video plus sync up to
1000ft through CAT-5 cable. The input to the SXGA Video
Transmission System is the output of a video source
transmitting RGB video signals plus sync. The signals are
received initially by the ISL59311; which converts the single
ended input RGB signals to three fully differential waveforms
with sync encoded on the discrete common modes of each
color channel and then drives the signals through a length of
CAT-5 cable. The signal is received by the EL9111, which
can provide 6-pole equalization for both high and low
frequency signal transmission line losses. Then the EL9111
converts the differential RGB video signals back into single
ended format while extracting the common mode component
for decoding. The single ended RGB signal is taken directly
from the output of the EL9111 and is ready for the output
device. The EL9111 Common Mode Decoder Circuit
receives the common mode signals and decodes them and
transmits H
SYNC
and V
SYNC
to the output device.
Disabling the Amplifiers with the Disable Pin
The Disable pin must be a logic low for normal operation of
the video amplifiers. When Disable is taken high, the
amplifiers are disabled, reducing supply V
CCA
supply
current. (The Disable pin has no effect on the Serial Digital
Transceiver - it is always enabled as long as power is
applied to V
CCD
.)
Serial Digital Transceiver Operation
The digital transceiver is a half-duplex design, either
receiving data on the S
IN
pins and sending it out on the
S
DATA
pin, or transmitting data from the S
DATA
pin out on
some the 2 S
OUT
pins. The digital transceiver operates in a
high speed (up to 50MBaud) differential mode. The S
DATA
pin is the half-duplex logic-level transmit and receive data
pin. S
DATA
is an output when Transmit = low (receive mode)
and an input when Transmit = high (transmit mode). This can
be made to work with existing designs that use independent
transmit and receive pins by connecting
S
DATA
directly to the
transmit pin and through a resistor to the receive pin.
Figure 21 shows an example of how to interface the
ISL59311 with an RS485 transceiver.
V
CCD
is the power source for the digital line interface drivers
and receivers.
