Overview
The TE3-LIU PEF 3452 Line Interface Unit is used to connect a DS3/STS-1 or E3
framer device to an analog transmission line. The line interface fulfills the relevant
standards for DS3 (44.736 Mbit/s), STS-1 (51.840 Mbit/s) and E3 (34.368 Mbit/s)
systems.
The TE3-LIU comes in a P-M
Q
FP-44-2 package (SMD) to save a significant amount
of board space. The integrated jitter attenuation further reduces overall system
complexity and cost.
This CMOS 3.3 V low power device contains an integrated pulse shaper to drive any line
length within the range of up to 1100 ft. without the need for external length selection
(Line Build Out).
The hardware configuration mode allows low cost systems with flexible device setting
without the need for a microprocessor.
An optional microprocessor mode allows the connection to a standard microprocessor
bus to control hardware settings.
