FEATURES

DESCRIPTION

Low Phase Noise Buffer/Driver

The LTC^®6957-1/LTC6957-2/LTC6957-3/LTC6957-4 is a

family of very low phase noise, dual output AC signal

buffer/driver/logic level translators. The input signal can

be a sine wave or any logic level (≤2V ). There are four

members of the family that differ in^Pt^-h^Peir output logic

signal type as follows:

Optimized Conversion of Sine Wave Signals to

Logic Levels

Three Logic Output Types Available

LVPECL

LVDS

CMOS

LTC6957-1: LVPECL Logic Outputs

Additive Jitter 45fs

(LTC6957-1)

RMS

LTC6957-2: LVDS Logic Outputs

Frequency Range Up to 300MHz

3.15V to 3.45V Supply Operation

Low Skew 3ps Typical

Fully Specified from –40°C to 125°C

12-Lead MSOP and 3mm × 3mm DFN Packages

LTC6957-3: CMOS Logic, In-Phase Outputs

LTC6957-4: CMOS Logic, Complementary Outputs

The LTC6957 will buffer and distribute any logic signal

with minimal additive noise, however, the part really

excels at translating sine wave signals to logic levels. The

early amplifier stages have selectable lowpass filtering

to minimize the noise while still amplifying the signal to

increase its slew rate. This input stage filtering/noise limit-

ing is especially helpful in delivering the lowest possible

phase noise signal with slow slewing input signals such

as a typical 10MHz sine wave system reference.
