Features

■ Operation up to 3 Gbits/s ■ Good sensitivity to low input signals ■ Low power dissipation ■ Surface-mount package A pplications ■ SONET/SDH transmission systems ■ Digital video transmission ■ Digital test instruments Functional Description The LG1602 is a gallium arsenide (GaAs) decision circuit. It features a sensitive broadband input ampli- fier and a D-type flip-flop that retimes and regener- ates an input data stream that is weakened by noise, jitter, and intersymbol interference. The LG1602 has complementary 50 Ω output buff- ers. dc feedback ensures input threshold control for input levels as low as 25 mV, when using dc balanced input data. The LG1602 is available in a hermetically sealed 16-lead glass-metal surface-mount package. 5-7667(F)r.3 Figure 1. LG1602 Functional Diagram

Electrical Characteristics

Bit rate = 2.488 Mbits/s NRZ and data pattern = 223 – 1 PRBS, unless otherwise indicated. See Figure 3 for the tim- ing and signal levels and Figure 5 for the test circuit, when using the TF1001A test fixture. Note:Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering evaluations. Typical values are for information purposes only and are not part of the testing requirements.
