General Description
The SY54020R is a fully differential, low voltage
1.2V/1.8V/2.5V CML 1:4 Fanout Buffer with active-low
Enable (/EN) and Fail-Safe Input (FSI). 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. FSI is a special circuit
designed to sense the amplitude of the input signal and
to latch the output when an invalid or no signal is
present at the input. The SY54020R can process clock
signals up to 2.5 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 SY54020R 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).
