SY56016R
Low Voltage 1.2V/1.8V/2.5V CML Differential
Line Driver/Receiver 6.4Gbps with Equalization
General Description
The SY56016R is a fully differential, low voltage
1.2V/1.8V/2.5V CML Line Driver/Receiver with input
equalization. The SY56016R can process clock signals as
fast as 5.0GHz or data patterns up to 6.4Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that interfaces to CML differential
signals, without any level-shifting or termination resistor
networks in the signal path. The differential input can also
accept AC-coupled CML, LVPECL, and LVDS signals.
Input voltages as small as 200mV (400mV_PP) are applied
before the 9”, 18” or 27” FR4 transmission line. For AC-
coupled input interface applications, an internal voltage
reference is provided to bias the V_T pin. The outputs are
CML, with extremely fast rise/fall times guaranteed to be
less than 80ps.
The SY56016R 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). The SY56016R is part of Micrel’s high-speed,
Precision Edge^® product line.
