TZA3004HL

FEATURES

• Data and clock recovery up to 622 Mbits/s (STM1/OC3

and STM4/OC12)

• Differential data input with 2.5 mV peak-to-peak typical

sensitivity

• Differential CML (Current-Mode Logic) data and clock

outputs with 50 Ω driving capability

• Adjustable CML output level

• Loop mode for system testing

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).
