Linear Technology LTC6957HMS-2#PBF

Description
The LTC69571/LTC69572/LTC69573/LTC69574 is a family of low phase noise, dual output AC signal buffer/driver/logic level translators. The input signal can be a sine wave or any logic level (≤2 Vpp). The four members of the family differ in their output logic signal type:
LTC69571: LVPECL Logic Outputs
LTC69572: LVDS Logic Outputs
LTC69573: CMOS Logic, InPhase Outputs
LTC69574: CMOS Logic, Complementary Outputs
The LTC6957 buffers and distributes any logic signal with minimal additive noise. It excels at translating sine wave signals to logic levels. The early amplifier stages have selectable lowpass filtering to minimize noise while amplifying the signal to increase its slew rate. This input stage filtering/noise limiting 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.
