LG1602 Decision Circuit
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 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.
