SIT92184AA-N

Clock Buffers, Drivers Overview

The SiT92184AA-N is an Automotive Grade 1, AEC-Q100 qualified high-performance LVCMOS clock buffer. It features a 1:4 output configuration with an additive phase jitter of less than 50 fs RMS and very low pin-to-pin skew under 50 ps. The device operates on a supply voltage ranging from 1.8 V to 3.3 V and supports a maximum frequency (FMAX) of 200 MHz. It includes integrated serial termination for 50 Ω channels and synchronous glitch-free output enable functionality. Packaged in an 8-pin, 2 x 2 mm DFN, it functions within an ambient operating temperature range of -40°C to +125°C.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging details. The 'T' suffix indicates tape and reel packaging with a quantity of 3,000 units. Confirm that the AA revision letter matches the required silicon version for your design implementation.

Clock Buffers, Drivers Selection Notes

Select this component when designing automotive timing circuits requiring low jitter and high reliability. Ensure the load capacitance does not exceed 5 pF for optimal rise/fall time performance. Verify that the input clock slew rate meets the minimum requirement of 2 V/ns to ensure proper signal integrity across the full operating temperature range.

Clock Buffers, Drivers Part Context

This part belongs to the SiT92184 family of high-performance LVCMOS clock buffers. The 'AA' designation specifically identifies the Automotive Grade 1 silicon revision, ensuring compliance with AEC-Q100 standards. It serves as a direct replacement for discrete buffering solutions in space-constrained automotive PCB layouts.

Clock Buffers, Drivers Replacement Considerations

SiTime recommends using the SiT6100DK field programming kit for prototype builds if custom configurations are needed. For production volumes, factory programming options are available to minimize lead times compared to standard quartz alternatives.
