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,
