SY89855U

Precision Low Power Differential LVPECL 4:1

MUX with 1:2 Fanout and Internal Termination

General Description

The SY89855U is a 2.5V/3.3V precision, high-speed,

4:1 differential multiplexer with 100K LVPECL (800mV)

compatible outputs, capable of handling clocks up to

2.5GHz and data streams up to 2.5Gbps. In addition, a

1:2 fanout buffer provides two copies of the selected

inputs.

Precision Edge

Features

• Select 1 of 4 differential inputs

• Provides two copies of the selected input

• Low power 260mW (V_CC= 2.5V)

The differential input includes Micrel’s unique, 3-pin

input termination architecture that allows customers to

interface to any differential signal (AC- or DC-coupled)

as small as 100mV without any level shifting or

termination resistor networks in the signal path. The

result is a clean, stub-free, low-jitter interface solution.

The outputs are 800mV LVPECL, (100K temperature

compensated) with fast rise/fall times guaranteed to be

less than 180ps.

• Guaranteed AC performance over temperature and

voltage:

– DC-to->2.5Gbps data rate throughput

– <410ps In-to-Q t_pd

– <180ps t_r/ t_ftimes

• Ultra low-jitter design:

– <10ps_PPtotal jitter (clock)

– <1ps_RMSrandom jitter

The SY89855U 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. For

applications that require higher performance, consider

the SY58029U. The SY89855U is part of Micrel’s high-

speed, Precision Edge^®product line.

– <10ps_PPdeterministic jitter

– <0.7ps_RMScrosstalk-induced jitter

• Unique, patent-pending input design minimizes

crosstalk

• Accepts an input signal as low as 100mV

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, LVPECL,

LVDS)

Typical Performance

• 800mV 100K LVPECL output swing

• Power supply 2.5V ±5% or 3.3V ±10%

• –40°C to +85°C temperature range

• Available in 32-pin (5mm x 5mm) MLF^®package

Applications

• Redundant clock and/or data distribution

• All SONET/OC-3 to OC-48 clock/data distribution

• Loopback

• All Fibre Channel applications

• All GigE applications

Markets

• LAN/WAN communication

• Enterprise servers

• ATE

• Test and measurement
