3.3V, 3.2Gbps DIFFERENTIAL 4:1 LVDS

MULTIPLEXER with 1:2 FANOUT and

INTERNAL TERMINATION

Micrel, Inc.

Precision Edge

SY89547L

FEATURES

■ Selects among four differential inputs

Precision Edge

■ Provides two copies of the selected input

■ Guaranteed AC performance over temp and voltage:

• DC-to > 3.2Gbps data rate throughput

DESCRIPTION

• < 620ps In-to-Out t

• < 150ps t /t

The SY89547L is a precision, high-speed 4:1 differential

multiplexer that provides two copies of the selected input.

The high speed LVDS (350mV) compatible outputs with a

guaranteed throughput of up to 3.2Gbps over temperature

and voltage.

r f

■ Unique input isolation design minimizes crosstalk

■ Ultra-low jitter design:

• < 1ps random jitter

• < 10ps deterministic jitter

RMS

The SY89547L differential inputs include Micrel’s unique,

3-pin internal termination design that allows access to the

• < 10ps total jitter (clock)

• < 0.7ps

crosstalk-induced jitter

termination network through a V pin. This feature allows

RMS

the device to easily interface to different logic standards,

both AC- and DC-coupled without external resistor-bias and

termination networks. The result is a clean, stub-free, low

jitter interface solution.

■ Internal input termination

■ Unique input termination and V pin accepts DC-

coupled and AC-coupled inputs (LVDS, LVPECL,

CML)

The SY89547L operates from a single 3.3V supply, and

is guaranteed over the full industrial temperature range

(–40°C to +85°C). For applications that require a 2.5V supply,

consider the SY89546U. For applications that only require

one differential output, consider the SY89544U or SY89545L.

The SY89547L is part of a Micrel’s Precision Edge product

family. All support documentation can be found on Micrel’s

web site at: www.micrel.com.

■ 350mV LVDS output swing

■ Power supply 3.3V ±10%

■ –40°C to +85°C temperature range

■ Available in 32-pin (5mm x 5mm) MLF™ package

APPLICATIONS

■ SONET/SDH multi-channel select applications

■ Fibre Channel applications
