SIT92114AI-T

Clock Buffers, Drivers Overview

The SiT92114AI-T is a high-performance LVCMOS clock buffer featuring an additive phase jitter of 50 fs RMS. It provides a synchronous glitch-free output enable function to prevent incorrect output cycles during state transitions. The device operates on a supply voltage ranging from 1.8 V to 3.3 V and supports a maximum frequency of 200 MHz. It includes integrated serial termination for 50 Ω channels and features very low pin-to-pin skew of less than 50 ps. The component is packaged in an 8-pin, 2 x 2 mm DFN format.

Clock Buffers, Drivers Procurement Notes

Verify the 'T' suffix indicates 3k unit tape and reel packaging. Confirm the 'I' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the ordering part number matches the specific revision letter required for the design.

Clock Buffers, Drivers Selection Notes

Select this component when low jitter buffering is critical for signal integrity. The 1:4 fan-out capability suits distributing a single clock source to multiple loads. Verify that the input clock slew rate meets the 2 V/ns requirement and that the power supply sequencing allows the clock input to be available after VDD ramp-up.

Clock Buffers, Drivers Part Context

This device belongs to the SiT92114 family of high-performance LVCMOS clock buffers. It is designed to replace traditional quartz-based buffers by offering superior robustness against vibration and shock while maintaining ultra-low jitter performance suitable for modern digital systems.
