General Description

The SY56017R is a fully differential, low voltage

1.2V/1.8V/2.5V CML 2:1 MUX with input equalization.

The SY56017R can process clock signals as fast as 4.5

GHz 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 LVPECL and LVDS signals. Input

voltages as small as 200mV (400mV

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

CML, with extremely fast rise/fall times guaranteed to be

less than 80ps.

The SY56017R 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 SY56017R is part of Micrel’s high-

speed, Precision Edge
