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 regener ates 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.
