SIT92184AA-T

Clock Buffers, Drivers Overview

The SiT92184AA-T is an Automotive Grade 1, AEC-Q100 qualified high-performance 1:4 LVCMOS clock buffer. It operates from a 1.71 V to 3.465 V supply and supports input frequencies up to 200 MHz. The device features synchronous glitch-free output enable (OE) via the 1G pin, ensuring no incorrect output cycles during state transitions. Additive phase jitter is specified at 0.05 ps RMS to 0.06 ps RMS depending on voltage, with very low pin-to-pin skew under 50 ps. It includes integrated serial termination for 50 Ω channels and is packaged in an 8-pin, 2 x 2 mm DFN.

Clock Buffers, Drivers Procurement Notes

Verify that the 'AA' suffix confirms the Automotive Grade 1 temperature range of -40°C to +125°C. Confirm the '-T' suffix indicates tape and reel packaging containing 3,000 units per reel. Ensure the specific frequency requirement matches the supported input range of 0 to 200 MHz.

Clock Buffers, Drivers Selection Notes

Select this component when driving four LVCMOS loads from a single source while requiring glitch-free switching. The device supports 1.8 V, 2.5 V, and 3.3 V supplies. Note that the CLKIN input is 3.3 V tolerant even at lower supply voltages. Verify that the 2 x 2 mm DFN package footprint fits the PCB layout constraints.
