LTC6957IDD-3#TRPBF

Clock Buffers, Drivers Overview

The LTC6957IDD-3#TRPBF is a low phase noise, dual-output buffer/driver/logic converter from Analog Devices. It features in-phase CMOS logic outputs and operates on a single 3.15V to 3.45V supply. The device accepts CML, CMOS, LVDS, or LVPECL inputs up to 300MHz. Packaged in a 12-lead DFN (3mm × 3mm) with an exposed ground pad, it supports surface mount assembly. Key electrical parameters include a typical propagation delay of 0.95ns at FILTA=FILTB=L and a supply current of 24mA with both outputs enabled.

Clock Buffers, Drivers Feature Summary

• Dual output buffer with in-phase CMOS logic levels
• Low additive jitter: 142fs RMS (10Hz to 50MHz offset)
• Supports CML, CMOS, LVDS, and LVPECL input signals
• Integrated selectable lowpass filtering for noise reduction

Clock Buffers, Drivers Applications

• System reference frequency distribution
• High-speed ADC and DAC clock drivers
• Broadband wireless transceivers
• Medical imaging systems

Clock Buffers, Drivers Procurement Notes

Verify the suffix #TRPBF indicates Tape & Reel packaging. Confirm the IDD designation corresponds to the Industrial temperature range (-40°C to 85°C). Ensure the specific lot traceability matches project requirements before finalizing orders.

Clock Buffers, Drivers Selection Notes

Select this variant when in-phase CMOS outputs are required. Compare against LTC6957-4 if complementary outputs are needed. Verify that the 3.15V–3.45V supply range aligns with the system power architecture. Check thermal dissipation requirements for the DFN package under maximum load conditions.

Clock Buffers, Drivers Part Context

This component belongs to the LTC6957 family, which includes variants with LVPECL (LTC6957-1), LVDS (LTC6957-2), and complementary CMOS (LTC6957-4) outputs. All members share identical input stages and low phase noise characteristics but differ in output driver topology.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitutes within the same family include LTC6957IDD-1#TRPBF, LTC6957IDD-2#TRPBF, and LTC6957IDD-4#TRPBF. These parts share the same package and pinout but provide different output logic types.
