New analog video delay lines for
Video applications from Intersil
Four new triple analog delay lines for video signals introduced
by Intersil that provide sharp, clear images for keyboard-video-mouse
applications or any video carried over long distances of
inexpensive twisted-pair cable.
The families of triple analog delay lines are ISL59920,
ISL59921, ISL59922, and ISL59923 provide skew compensation
between three high-speed signals and are ideal for compensating
for the skew introduced by a typical CAT-5, CAT-6 or CAT-7
cable (with differing electrical lengths on each twisted
pair) when transmitting analog video.
Intersil's triple analog video delay lines offer bandwidths,
ranging from 150MHz up to 230MHz, which increases the range
of video resolutions that can be handled up to UXGA and
1080p. The new family also has significantly reduces offset
to just +/-25mV.
The ISL59920 features up to 62ns of delay compensation
in 2ns steps, with a bandwidth of 153 MHz to compensate
for the skew encountered in 1000 feet (300m) of CAT 5/6/7
cable. Users needing higher-bandwidth solutions over shorter
distances may opt for the ISL59921 or ISL59922, which feature
200MHz or 230MHz -3dB bandwidth (typ).The ISL59923 has bandwidth
of 153MHz and with 30ns of total delay and suited for shorter
reach, lower resolution installations.
Using a simple serial interface, the ISL59920, ISL59921,
ISL59922, and ISL59923s delays are programmable in steps
of 2, 1.5, 1, or 2ns (respectively) for up to a total delay
of 62, 46.5, 31, or 30ns (respectively) on each channel.
The gain of the video amplifiers can be set to x1 (0dB)
or x2 (6dB) for back-termination.
Delay lines solve the skew problem encountered when RGB
video is sent over twisted pair cables. The triple delay
line enables the designer to slow down the fastest two colors
so that all three colors arrive simultaneously. The result
is a sharp, clear image.
