General Description

The SY54017R is a fully differential, low voltage

1.2V/1.8V CML 2:1 MUX with Fail Safe Inputs.

The

SY54017R can process clock signals as fast as 2.5GHz

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, (AC- or DC-coupled

without

any

level-shifting

or

termination

resistor

networks in the signal path. For AC-coupled input

interface applications, an internal voltage reference is

extremely fast rise/fall times guaranteed to be less than

95ps.

The SY54017R operates from a 2.5V ±5% core supply

and a 1.8V or 1.2V ±5% output supply and is

guaranteed over the full industrial temperature range

(–40°C to +85°C). The SY54017R is part of Micrel’s

high-speed, Precision Edge
