FEATURES

ꢀ Selects among four differential inputs

Precision Edge

ꢀ Guaranteed AC performance over temp and voltage:

• DC-to > 3.2Gbps data rate throughput

DESCRIPTION

• < 600ps In-to-Out t

The SY89544U is a fast, low-jitter, 4:1 differential MUX

with an LVDS (350mV) compatible output with guaranteed

data rate throughput of 3.2Gbps over temperature and

voltage.

• < 150ps t /t

ꢀ Ultra low-jitter design:

• < 1ps

• < 10ps deterministic jitter

The SY89544U differential inputs include a unique, 3-pin

internal termination that allows access to the termination

network through a V pin. This feature allows the device to

ꢀ Unique input isolation design minimizes crosstalk

ꢀ Internal input termination

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.

ꢀ Unique input termination and V pin accepts DC-

Coupled and AC-Coupled inputs (LVDS, LVPECL,

CML)

The SY89544U operates from a single 2.5V supply and

is guaranteed over the full industrial temperature range

(–40°C to +85°C). For applications that require a 3.3V supply,

consider the SY89545L. For applications that require two

differential outputs, consider the SY89546U or SY89547L.

ꢀ 350mV LVDS output swing

ꢀ CMOS/TTL compatible MUX select

ꢀ Power supply 2.5V ±5%

ꢀ –40°C to +85°C temperature range

The SY89544U is part of Micrel’s Precision Edge product

ꢀ Available in 32-pin (5mm × 5mm) MLF package

family.
