General Description

The SY58611U is a 2.5V, high-speed, fully differential

LVDS 2:1 MUX capable of processing clocks up to

2.5GHz and data up to 3.2Gbps. SY58611U is

optimized to provide a buffered output of the selected

input with less than 20ps of skew and less than 10ps

total jitter. Patented MUX Isolation design reduces

crosstalk and provides superior signal integrity.

The differential inputs include Micrel’s unique, 3-pin

input termination architecture that interfaces to LVPECL,

LVDS or CML differential signals, (AC- or DC-coupled)

as small as 100mV

shifting or termination resistor networks in the signal

path. For AC-coupled input interface applications, an

integrated reference voltage (V

the V

times guaranteed to be less than 120ps.

The SY58611U operates from a 2.5V ±5% supply and is

guaranteed over the full industrial temperature range

(–40°C to +85°C). For applications that require CML or

LVPECL output, consider the SY58609U and

SY58610U, 2:1 MUX with 400mV and 800mV output

swings respectively. The SY58611U is part of Micrel’s

high-speed, Precision Edge
