General Description
The SY56034AR is a fully differential, low voltage
1.2V/1.8V/2.5V CML 2:6 (2+4) MUX with crosspoint
capability. The SY56034AR can process clock signals
as fast as 5GHz or data patterns up to 6.4Gbps.
The differential input includes Micrel’s unique, 3-pin
input termination architecture that interfaces to
LVPECL, LVDS or CML differential signals as small
as 100mV (200mV
termination resistor networks in the signal path. For
AC-coupled input interface applications, an internal
voltage reference is provided to bias the V
outputs are 400mV CML, with extremely fast rise/fall
times guaranteed to be less than 80ps.
The SY56034AR operates from a 2.5V ±5% core
supply and a 1.2V/1.8V/2.5V ±5% output supply and
is guaranteed over the full industrial temperature
range (–40°C to +85°C). The SY56034AR is part of
Micrel’s high-speed, Precision Edge
Datasheets and support documentation can be found
