LTC6957HMS-3#TRPBF

Clock Buffers, Drivers Overview

The LTC6957HMS-3#TRPBF is a low phase noise, dual output buffer/driver/logic converter from Analog Devices. It features in-phase CMOS logic outputs and supports input frequencies up to 300 MHz. The device operates on a single supply voltage ranging from 3.15V to 3.45V. It accepts various input signal types including CML, CMOS, LVDS, and LVPECL. Packaged in a 12-lead MSOP with Tape & Reel configuration, it is specified for operation over an extended temperature range of -40°C to 125°C.

Clock Buffers, Drivers Feature Summary

• Dual output buffer with in-phase CMOS logic signals
• Low additive jitter of 53fs RMS (12kHz to 20MHz offset)
• Supports CML, CMOS, LVDS, and LVPECL inputs
• Operates within 3.15V to 3.45V supply range

Clock Buffers, Drivers Applications

• System reference frequency distribution
• High-speed ADC and DAC clock drivers
• Military and secure radio systems
• Broadband wireless transceivers

Clock Buffers, Drivers Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging. Confirm the 'H' grade designation corresponds to the -40°C to 125°C operating temperature range. Ensure the ordering part number matches the specific in-phase CMOS output variant required for the design.

Clock Buffers, Drivers Selection Notes

Select this component when in-phase CMOS outputs are required. Compare against the LTC6957-4 if complementary outputs are needed instead. Verify that the input signal type (CML/LVDS/etc.) is compatible with the internal self-biasing circuitry. Check power consumption requirements against the typical 27.5mA supply current at maximum frequency.

Clock Buffers, Drivers Part Context

This part belongs to the LTC6957 family, which includes variants with LVPECL (LTC6957-1), LVDS (LTC6957-2), and complementary CMOS (LTC6957-4) outputs. The 'IMS' package code denotes the 12-lead plastic MSOP form factor. The '#TRPBF' suffix specifies the lead-free tape and reel shipping format.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes within the same family include LTC6957HMS-4#TRPBF for complementary outputs or LTC6957IMS-3#TRPBF for the industrial temperature range (-40°C to 85°C). Cross-family replacements require verification of pinout compatibility and electrical parameter alignment.
