DESCRIPTION
The SY100ELT982 is a high speed PECL-to-CML
translator. The output current is DC current controlled by
IRSET, current through the resistor RSET. The output OUT
is LOW when output enable is HIGH.
The device incorporates complementary open collector
outputs with a capability of driving peak current of 25mA.
The SY100ELT982 utilizes the high performance
bipolar ASSET⢠technology.
