GENERAL DESCRIPTION
The TZA3014 is a low gain postamplifier with a LOS
detector and a RSSI designed for use in critical signal path
control applications, such as loop-through or Wavelength
Division Multiplexing (WDM). The signal path is capable of
operating from 50 kHz up to 2.5 GHz.
The TZA3014 can be delivered in HTQFP32 and HBCC32
packages and as bare die.
