General Description
The SY54020AR is a fully differential, low voltage
1.2V/1.8V/2.5V CML 1:4 Fanout Buffer with active-low
Enable (/EN). The Enable is synchronous so that the
outputs will only be enabled/disabled when they are
already in the LOW state. This avoids any chance of
generating a runt clock pulse when the device is
enabled/disabled as can happen with an asynchronous
control. When this device is used as a clock fanout,
disabling the downstream clock may reduce system
power. The SY54020AR can process clock signals as
fast as 3.2 GHz or data patterns up to 3.2Gbps.
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
(200mVpp) without any level-shifting or termination
resistor networks in the signal path. For AC-coupled
input
interface
applications,
an
internal
voltage
reference is provided to bias the VT pin. The outputs are
CML, with extremely fast rise/fall times guaranteed to be
less than 100ps.
The SY54020AR operates from a 2.5V ±5% core supply
and a 1.2V, 1.8V or 2.5V ±5% output supply and is
guaranteed over the full industrial temperature range (–
40°C to +85°C).
