SY89859U

Precision Low-Power 8:1 MUX with Internal

Termination and 1:2 LVPECL Fanout Buffer

General Description

The SY89859U is a low jitter, low-power, high-speed

8:1 multiplexer with a 1:2 differential fanout buffer

optimized for precision telecom and enterprise server

distribution applications. The SY89859U distributes

clock frequencies from DC to >2.5GHz, and data rates

to 2.5Gbps guaranteed over temperature and voltage.

Precision Edge^®

Features

• Selects between 1 of 8 inputs, and provides 2

precision, low skew 100K-compatible LVPECL

output copies

The SY89859U differential input includes Micrel’s

unique, 3-pin input termination architecture that

directly interfaces to any differential signal (AC- or

DC-coupled) as small as 100mV (200mVpp) without

level shifting or termination resistor networks in the

signal path. The outputs are 800mV, 100K-compatible

LVPECL with extremely fast rise/fall time guaranteed

to be less than 180ps.

• Low power: 150mW typ. (2.5V)

• Guaranteed AC performance over temperature and

voltage:

– DC to >2.5Gbps

– DC to >2.5GHz

– <690ps propagation delay

– <180ps t_r/t_ftime

The SY89859U features a patent-pending isolation

design that significantly improves on channel-to-

channel crosstalk-induced jitter performance.

– <20ps skew (output-to-output)

• Unique, patent-pending channel-to-channel

isolation design provides superior crosstalk

performance

The SY89859U operates from a 2.5V ±5% or 3.3V

±10% supply and is guaranteed over the full industrial

temperature range of –40°C to +85°C. The SY89859U

is part of Micrel’s high-speed, Precision Edge^®product

line.

• Ultra-low jitter design:

– <1ps_RMSrandom jitter

– <10ps_PPdeterministic jitter

– <10ps_PPtotal jitter (clock)

– <1ps_RMScycle-to-cycle jitter

– <0.7ps_RMScrosstalk-induced jitter

All support documentation can be found on

Micrel’s web site at: www.micrel.com.

• Unique, patented input termination and VT pin

accepts DC- and AC-coupled inputs (CML, PECL,

LVDS)

• Power supply 2.5V ±5% or 3.3V ±10%

• –40°C to +85°C industrial temperature range

• Available in 44-pin (7mm x 7mm) QFN package

Applications

• Data communication systems

• All SONET/SDH data/clock applications

• All Fibre Channel applications

• All Gigabit Ethernet applications
