SY89852U

Precision Low Power Differential 2:1

LVPECL MUX with Internal Termination

General Description

The SY89852U is a 2.5V/3.3V precision, high-

speed, 2:1 differential MUX capable of handling

clocks up to 2.5GHz and data streams up to

2.5Gbps.

Precision Edge^®

Features

• Provides a low jitter copy of the selected input

• Superior alternative to the EP58 2:1 MUX

• Low power: 58mW (2.5V nominal, no load)

• Guaranteed AC performance over temperature

and supply voltage:

– DC- to > 2.5Gbps data rate throughput

– DC- to > 2.5GHz clock f_MAX

– < 340ps In-to-Out t_pd

The differential input includes Micrel’s unique, patent

pending 3-pin input termination architecture that

allows users to interface to any differential signal

(AC- or DC-coupled) as small as 100mV (200mV_pp)

without any level shifting or termination resistor

networks in the signal path. The unique, patent input

isolation design minimizes crosstalk minimizing

crosstalk induced jitter. The outputs are 800mV

LVPECL, with extremely fast rise/fall time

guaranteed to be less than 180ps.

– < 180ps t_r/t_ftime

• Ultra-low Jitter Design:

– <1ps_(rms)random jitter

– <10ps_(pp)deterministic jitter

– <10ps_(pp)total jitter (clock)

– <0.7ps_(rms)crosstalk induced jitter

The SY89852U operates from a 2.5V ±5% supply or

a 3.3V ±10% supply and is guaranteed over the full

industrial temperature range of –40°C to +85°C.

The SY89852U is part of Micrel’s high-speed,

Precision Edge^®product line. All support

documentation can be found on Micrel’s web site at:

www.micrel.com.

• Unique, patent-pending input isolation design

minimizes crosstalk

• Unique, patent pending input termination and VT

pin accepts DC-coupled and AC-coupled inputs

(CML, PECL, LVDS)

Typical Applications

• Typical 800mV (100k) LVPECL output swing

• Power supply 2.5V +5% or 3.3V +10%

• Industrial temperature range –40^oC to +85^oC

• Available in ultra-small (3mm x 3mm) 16-pin MLF^®

package

Applications

• Redundant clock distribution

• SONET/SDH clock/data distribution

• Loopback

• Fibre Channel distribution

Markets

• LAN/WAN

• Enterprise servers

• ATE

• Test and measurement
