SY58020U - 1:4 CML Fanout Buffer/Translator

General Description

The SY58020U is a 2.5V/3.3V precision, high-speed, fully differential 1:4 CML fanout buffer.

Optimized to provide four identical output copies with less than 15ps of skew and 27fsRMS of typical additive phase jitter, the SY58020U can process clock signals as fast as 6GHz.

SY58020U 6GHz, 1:4 CML Fanout Buffer/Translator with Internal I/O Termination General Description The SY58020U is a 2.5V/3.3V precision, high-speed, fully differential 1:4 CML fanout buffer. Optimized to provide four identical output copies with less than 15ps of skew and 27fsRMS of typical additive phase jitter, the SY58020U can process clock signals as fast as 6GHz. The differential input includes Micrel’s unique, 3-pin input termination architecture that interfaces to differential LVPECL, LVDS, and CML signals (AC- or DC-coupled) as small as 100mV without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an on-board output reference voltage (VREF-AC) is provided to bias the VT pin.
