transmission systems.
It incorporates eight independent receivers and eight independent transmitters in a single LQFP-144 or PBGA-160 package.
The transmit output drivers provide low impedance, constant during marks and spaces and constant pulse amplitudes independent of supply voltage variations.
The LXT381 may be configured for unbalanced 75Ω or for balanced 120Ω systems without external component changes in the transmit section.
The transmit return loss performance exceeds latest ETSI return loss recommendations...
