LINK ELECTRONICS, INC.
SERIAL DIGITAL DISTRIBUTION AMPLIFIER
MODEL LEI-555
FEATURES
Serial Digital Input
Re-Clocking
Six Serial Outputs
Fault Indication
Re-Shaped
Equalized
Composite & Component
The LINK LEI-555 serial distribution amplifier
restores the incoming signal to its proper
amplitude. The signal is reshaped with automatic
equalization, re-slicing and DC restoration. The
LEI-555 re-clocks the input signal for distribution
over longer distance cables, up to 500 feet. Six
outputs are provided on the rear panel.
A module fault LED on the front panel indicates a
weak signal or no input signal present. The
sensitivity of the LED indicator may be adjusted to
suit the users needs.
The LEI-555 input signal is may be composite
143Mb/s or component 270Mb/s. An internal
jumper selects the desired standard. The unit has
two LED's that show power supply status and
signal present.
TheLEIseriesdigitalproductsarecompactdesign
that allow three modules to mount in the PRT-700
mounting tray.
Backed by Link's 10-year warranty, the LEI-555
will provide years of outstanding performance.
