2:1 MUX input is included for redundant clock switchover
applications.
termination architecture that allows the device to interface
to any differential signal (AC- or DC-coupled) as small as
100mV 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 110ps.
3.3V ±10% supply and is guaranteed over the full industrial
temperature range of –40°C to +85°C. For applications that
require CML outputs, consider the SY58034U or for 400mV
LVPECL outputs the SY58036U. The SY58035U is part of

Micrel, Inc. OUTPUT INTERFACE APPLICATIONS LVPECL has high input impedance, very low output (open emitter) impedance, and small signal swing, which results in low EMI. LVPECL is ideal driving 50Ω and 100Ω controlled impedance transmission lines. There are several techniques for terminating the LVECL output: parallel-thevenin equivalent +3.3V R1 +3.3V 130Ω ...
