LTC6957-1/LTC6957-2/ LTC6957-3/LTC6957-4 Low Phase Noise, Dual Output Buffer/Driver/ Logic Converter FEATURES DESCRIPTION ? n Low Phase Noise Buffer/Driver The LTC 6957-1/LTC6957-2/LTC6957-3/LTC6957-4 is a n family of very low phase noise, dual output AC signal Optimized Conversion of Sine Wave Signals to buffer/driver/logic level translators. The input signal can Logic Levels n be a sine wave or any logic level (?2V ).
