DESCRIPTION
APPLICATIONS
GENERAL DESCRIPTION
The TZA3019 is a low gain postamplifier multiplexer with a
dual RSSI and/or LOS detector that is designed for use in
critical signal path control applications, such as
loop-through, redundant channel switching or Wavelength
Division Multiplexing (WDM). The signal path is
unregistered, so no clock is required for the data inputs.
The signal path is fully differential and delay matched. It is
capable of operating from 50 kHz to 2.5 GHz.
The TZA3019 HTQFP32 and HBCC32 packages can be
delivered in three versions:
PACKAGE
