DESCRIPTION
The TZA3004HL is a data and clock recovery IC intended
for use in SDH (Synchronous Digital Hierarchy) and
SONET (Synchronous Optical Network) systems.
The circuit recovers data and extracts the clock signal from
an incoming bitstream up to 622 Mbits/s. It can be
configured for use in STM1/OC3 and STM4/OC12
systems.
APPLICATIONS
·
Data and clock recovery in STM1/OC3 and STM4/OC12
transmission systems (up to 622 Mbits/s).
