SY89834U

FEATURES

■ Selects between two LVTTL/CMOS inputs and

Precision Edge

provides 4 LVPECL output copies

■ Guaranteed AC performance over temperature

and voltage:

DESCRIPTION

• DC-to >1.0GHz throughput

• <500ps propagation delay (IN-to-Q)

• < 20ps within-device skew

• < 225ps rise/fall time

The SY89834U is a high-speed, 1GHz LVTTL/CMOS-to-

LVPECL fanout buffer/translator optimized for high-speed

ultra-low skew applications. The input stage is designed to

accept two single-ended LVTTL/CMOS compatible signals

that feed into a 2:1 MUX. The selected input is translated

and distributed as four differential 100K LVPECL outputs.

Within device skew is guaranteed to be less than 20ps over

supply voltage and temperature.

■ Ultra-low jitter design:

• < 1ps

cycle-to-cycle jitter

random jitter

RMS

• < 10ps deterministic jitter

• < 10ps total jitter (clock)

The single-ended input buffers accept TTL/CMOS logic

levels. The internal threshold of the buffers is defined as

■ Low voltage 2.5V and 3.3V supply operation

■ 100K LVPECL outputs

■ Industrial temperature range: –40°C to +85°C

■ Includes a 2:1 MUX select input

The SY89834U is a part of Micrel's high-speed Precision

Edge family. For applications that require a different I/O

combination, consult Micrel's website at: www.micrel.com,

and choose from a comprehensive product line of high-

speed, low-skew fanout buffers, translators and clock

generators.

■ Accepts single-ended TTL/CMOS inputs and

provides four LVPECL outputs

■ Available in 16-pin (3mm × 3mm) MLF™ package
