LINK ELECTRONICS, INC.
SERIAL DIGITAL DISTRIBUTION AMPLIFIER
MODEL LEI-555
MADE IN THE USA
500 SERIES
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.
The LEI series digital products are compact design
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.
