Data Sheet February 1999 LG1602 Decision Circuit Features s s s s Functional Description The LG1602 is a gallium arsenide (GaAs) decision circuit. It features a sensitive broadband input amplifier and a D-type flip-flop that retimes and regenerates an input data stream that is weakened by noise, jitter, and intersymbol interference. The LG1602 has complementary 50 Ω output buffers. 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. V+OUT V–OUT Operation up to 3 Gbits/s Good sensitivity to low input signals Low power dissipation Surface-mount package Applications s s s SONET/SDH transmission systems Digital video transmission Digital test instruments V–REF V–IN V+IN V+REF 110 pF 25 kΩ 50 Ω D 50 Ω 25 kΩ 110 pF D Q VSS 2 pF V–CLK 50 Ω 50 Ω V+CLK 2 pF GND 5-7667(F)r.3 Figure 1.

Data Sheet February 1999 LG1602 Decision Circuit Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent or latent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability. Table 2.

Recommended Operating Conditions Parameter Case Temperature Power Supply Symbol tCASE VSS Min 0 –4.7 Max 75 –5.7 Unit °C V Handling Precautions Although protection circuitry has been designed into this device, proper precautions should be taken to avoid exposure to electrostatic discharge (ESD) during handling and mounting. Lucent employs a human-body model (HBM) and a charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation. No industrywide standard has been adopted for the CDM. However, a standard HBM (resistance = 1500 Ω, capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes. The HBM ESD threshold presented here was obtained by using these circuit parameters. Table 4. ESD Threshold HBM ESD Threshold Device LG1602 Voltage ≥200 V Mounting and Connections Certain precautions must be taken when using solder. For installation using a constant temperature solder, temperatures of under 300 °C may be employed for periods of time up to 5 seconds, maximum. For installation with a soldering iron (battery operated or nonswitching only), the soldering tip temperature should not be greater than 300 °C and the soldering time for each lead must not exceed 5 seconds. Lucent Technologies Inc. 3 LG1602 Decision Circuit Data Sheet February 1999 Electrical Characteristics Bit rate = 2.488 Mbits/s NRZ and data pattern = 223 – 1 PRBS, unless otherwise indicated. See Figure 3 for the timing 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.
