SY89851U

Low Power, 3GHz, 1:2 LVPECL Fanout

Buffer/Translator with Internal Termination

General Description

The SY89851U is a low jitter, low skew, high-speed

1:2 differential fanout buffer optimized for precision

telecom

and

enterprise

server

distribution

Precision Edge^®

applications. The SY89851U distributes clock

frequencies from DC to >3GHz, and data rates to

2.5Gbps guaranteed over temperature and voltage.

Features

• Precision 1:2, 800mV LVPECL fanout buffer

• Low power consumption: 80mW typ. (2.5V)

• Guaranteed AC performance over temperature

The SY89851U 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

any 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.

and voltage:

– DC to >3GHz clock throughput

– <340ps propagation delay

– <180ps rise/fall time

– <20ps output-to-output skew

The SY89851U 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

SY89851U 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)

• Unique, patented input termination and VT pin

accepts DC- and AC-coupled inputs (CML,

LVPECL, LVDS)

All support documentation can be found on Micrel's

web site at www.micrel.com.

• 100K LVPECL-compatible outputs

• Power supply 2.5V ±5% or 3.3V ±10%

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

• Available in 16-pin (3mm x 3mm) QFN package

Applications

• All SONET and GigE clock distribution

• Fibre Channel applications

• Backplane distribution

• High-end, low skew, multiprocessor synchronous

clock distribution
