SDH/SONET STM4/OC12 and

1.25 Gbits/s Gigabit Ethernet postamplifiers

Product specification

TZA3044; TZA3044B

FEATURES

• Pin compatible with the NE/SA5224 and NE/SA5225 but

with extended power supply range and less external

component count

• Wideband operation from 1.0 kHz to 1.25 GHz typical

• Applicable in 622 Mbits/s SDH/SONET receivers and

1.25 Gbits/s Gigabit Ethernet receivers

• Single supply voltage from 3.0 to 5.5 V

• Positive Emitter Coupled Logic (PECL) compatible data

outputs

• Positive Emitter Coupled Logic (PECL) compatible

status outputs (TTL compatible status outputs for the

TZA3044B)

• Programmable input signal level detection to be

adjusted using a single external resistor

• On-chip DC offset compensation without external

capacitor.

APPLICATIONS

• Digital fibre optic receiver for SDH/SONET STM4/OC12

and Gigabit Ethernet applications

• Wideband RF gain block.

GENERAL DESCRIPTION

The TZA3044 is a high gain limiting amplifier that is

designed to process signals from fibre optic preamplifiers

like the TZA3043 and TZA3023. It is pin compatible with

the NE/SA5224 and NE/SA5225 but with extended power

supply range, and needs less external components.

Capable of operating up to 1.25 Gbits/s, the chip has input

signal level detection with a user-programmable threshold.

The data and level detection status outputs are differential

outputs for optimum noise margin and ease of use.

The TZA3044B has the same functionality as the

TZA3044, but with TTL compatible status outputs

(pins ST and STQ), and TTL compatible JAM input.
