SY89856U 2GHz, Low-Power, 1:6 LVPECL Fanout Buffer with 2:1 Input MUX and Internal Termination General Description The SY89856U is a 2.
5V/3.
3V precision, high-speed, 1:6 fanout capable of handling clocks up to 2.
0GHz.
A differential 2:1 MUX input is included for redundant clock switchover applications.
The differential input includes Micrel’s unique, 3-pin input termination architecture that allows the device to interface to any differential signal (AC- or DC-coupled) as small as 100mV (200mVpp) without any level shifting or termination resistor networks in the signal path.
The outputs are LVPECL (100k, temperature compensated), with extremely fast rise/fall times guaranteed to be less than...
