Overview
Overview
TE3-LIUPEF 3452 Line Interface Unit used connect DS3/STS-1 framer device analog transmission line. line interface fulfills relevant standards (44.736 Mbit/s), STS-1 (51.840 Mbit/s) (34.368 Mbit/s) systems. TE3-LIUcomes P-MQFP-44-2 package (SMD) save significant amount board space. integrated jitter attenuation further reduces overall system complexity cost. This CMOS power device contains integrated pulse shaper drive line length within range 1100 without need external length selection (Line Build Out). hardware configuration mode allows cost systems with flexible device setting without need microprocessor. optional microprocessor mode allows connection standard microprocessor control hardware settings.

Operational Description
Operational Description
Operational Overview
TE3-LIUcan operated three principle modes, which either STS-1 mode. This basic operation mode selection stable before reset signal goes inactive. device programmable selection. Direct connection microprocessor data possible using chip select (CS) write strobe.
Device Reset
TE3-LIUis forced reset state signal input (for minimum period page Page 51). During reset, output stages high impedance state, internal flip-flops reset. basic device mode (DS3, STS-1 jitter attenuation) selected during reset enable internal PLLs adjust. After reset control input values cleared. default control values (driven internal pullups) activated after applied first time after reset.
Device Power Down
TE3-LIUcan into power down state reduce power consumption, active. Power down mode selected setting RL=LL=1. Receive transmit circuits switched including internal PLLs transmit line driver. Recovery from power down mode achieved clearing either and/or After recovery from power down, internal PLLs need stabilize again. REFCLK must active recover from power down mode. Internal pullup resistors switched during power down prevent open input lines from floating. Note: switching directly from local loop remote loop vice versa, make sure that there signal overlap, which would device into power down mode unintentionally.
Transmit Line Inactive
transmitter used, switched into inactive mode setting XLT=1. During inactive state common mode voltage output XL2. transmit stopped output enabled again XLT=0 without wait time.
