LTC6957IMS-3#PBF

The LTC6957IMS-3#PBF from Analog Devices is a low phase noise, dual output AC signal buffer, driver, and logic level translator. It is designed to buffer and distribute logic signals with minimal additive noise, excelling at translating sine wave signals to logic levels. The device supports input signals that are sine waves or any logic level up to 2VP-P.

Key electrical specifications include a frequency range up to 300MHz and a supply voltage range of 3.15V to 3.45V. It features CMOS logic outputs and can accept CML, CMOS, LVDS, or LVPECL inputs. The device offers a 1:2 output ratio and supports differential signaling. Additive jitter is specified at 45fs RMS for the LTC6957-1 variant, and channel-to-channel skew is a typical 3ps.

This component is fully specified for operation across a wide temperature range of -40°C to 125°C, though the product data lists an operating temperature of -40°C to 85°C. It is available in a 12-MSOP package and a 12-TSSOP package, both suitable for surface mounting.

The LTC6957 family is ideal for applications requiring low phase noise buffer/drivers, optimized conversion of sine wave signals to logic levels, and system reference frequency distribution. It is also suitable for high-speed ADC, DAC, and DDS clock driving.
