| PECL-TO-CML TRANSLATOR w/o ENABLE FEATURES s s s s s s s s Up to 1.25Gbps operation 25mA peak drive current Adjustable output current Separate output enable Differential inputs for data 75K input pulldown resistor Single power supply Available in a tiny 10-pin (3mm) MSOP PRELIMINARY SY100ELT982 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 ASSETTM technology.

Ground Differential PECL 100K compatible inputs. This PECL 100K compatible input enables data translation. When Enable asserted HIGH, OUT = IOUT, /OUT = 0mA. Open collector outputs from the output buffer drive these differential current outputs. Voltage reference for use with RSET. External resistor to adjust output current.
