GENERAL DESCRIPTION
The AD8120 is a triple broadband skew-compensating delay line
that corrects for time mismatch between video signals incurred
by transmission in unshielded twisted pairs of Category 5 and
Category 6 type cables. Skew between the individual pairs exists
in most types of multipair UTP cables due to the different twist
rates that are used for each pair to minimize crosstalk between
pairs. For this reason, some pairs are longer than others, and in
long cables, the difference in propagation time between two pairs
can be well into the tens of nanoseconds.
The AD8120 contains three delay paths that provide broadband
delays up to 50 ns, in 0.8 ns increments, using 64 digital control
steps or analog control adjustment. The delay technique used in
the AD8120 minimizes noise and offset at the outputs.
The bandwidth of the AD8120 ranges from 150 MHz to 200 MHz,
depending on the delay setting. This wide bandwidth makes the
AD8120 ideal for use in applications that receive high resolution
video over UTP cables.
The logic circuitry of the AD8120 provides individual delay con-
trols for each channel. The delay times are set independently
using a standard 4-wire SPI bus or a standard I2C bus, or by
applying analog control voltages to the VCR, VCG, and VCB pins.
Analog control offers a simple solution for systems that do not
have digital control available.
The AD8120 is designed to be used with the AD8123 triple
UTP equalizer in video over UTP applications, but it can
also be used in other applications where similar controllable
broadband delays are required.
The AD8120 is available in a 5 mm × 5 mm, 32-lead LFCSP
and is rated to operate over the industrial temperature range
of 40°C to +85°C.
