SY89540U

Precision Low Jitter 4x4 LVDS Crosspoint

Switch with Internal Termination

General Description

The SY89540U is a low-jitter, low skew, high-speed

4x4 crosspoint switch optimized for precision

telecom and enterprise server/storage distribution

applications. The SY89540U guarantees data-rates

up to 3.2Gbps over temperature and voltage.

Precision Edge^®

Features

• Provides crosspoint switching between any input

pairs to any output pair

The SY89540U 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 (200mV_pp) without

any level shifting or termination resistor networks in

the signal path. The LVDS compatible outputs

maintain extremely fast rise/fall times guaranteed to

be less than 120ps.

• Patent pending, channel-to-channel isolation

design provides superior crosstalk performance

• Guaranteed AC performance over temperature

and voltage:

• DC-to-3.2Gbps throughput

– <480ps propagation delay

– <120ps rise/fall time

The SY89540U features a patent-pending isolation

design that significantly improves on channel-to-

channel crosstalk performance.

– <30ps output-to-output skew

• Ultra-low jitter design:

– <1ps_RMSrandom jitter

The SY89540U operates from a 2.5V ±5% supply

and is guaranteed over the full industrial

temperature range (–40°C to +85°C). The

SY89540U is part of Micrel’s high-speed, Precision

Edge^®product line.

– <10ps_PPdeterministic jitter

– <10ps_PPtotal jitter (clock)

– <0.7ps_RMScrosstalk induced jitter

• Patent pending 50ꢀ input termination, extended

CMVR, and VT pin accepts DC- and AC-coupled

differential inputs

All support documentation can be found on Micrel’s

web site at www.micrel.com.

• 350mV LVDS output swing

• Power supply 2.5V ±5%

Typical Performance

• –40°C to +85°C temperature range

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

• Pb-Free Green package

2.5Gbps Output

Applications

• All SONET/SDH channel select applications

• All Fibre Channel multi-channel select

applications

• All Gigabit Ethernet multi-channel select

applications
