LTC6957IMS-3#TRPBF

The LTC6957IMS-3#TRPBF from Analog Devices is a family of very low phase noise, dual output AC signal buffer/driver/logic level translators. It is designed to buffer and distribute logic signals with minimal additive noise, excelling at translating sine wave signals to logic levels. The device features selectable low-pass filtering in its early amplifier stages to minimize noise and amplify the signal, increasing slew rate. This is particularly beneficial for delivering low phase noise signals with slow slewing inputs.

Key electrical specifications include a frequency range up to 300MHz, a supply voltage operation from 3.15V to 3.45V, and low channel-to-channel skew of 3ps typical. The additive jitter is rated at 45fsRMS for the LTC6957-1 variant. The device supports various input types including CML, CMOS, LVDS, and LVPECL, with CMOS logic outputs.

This component is available in a 12-MSOP package and a 3mm x 3mm DFN package. It is fully specified for operation across a wide temperature range of -40°C to 125°C. The surface mount mounting type is suitable for automated assembly processes. Applications include system reference frequency distribution, high-speed ADC/DAC/DDS clock drivers, and military/secure radio systems.
