SIT92113AI-T

Clock Buffers, Drivers Overview

The SiT92113AI-T is a five-output ultra-low jitter LVCMOS fan-out buffer designed for high-frequency clock distribution. It features an additive jitter performance of 50 fs RMS and supports input frequencies up to 250 MHz. The device accepts LVPECL, LVDS, LVCMOS, SSTL, HCSL, and OSC inputs, distributing the selected signal to five LVCMOS outputs. It operates with independent core (VDD) and output (VDDO) supplies ranging from 1.35 V to 3.465 V. The component is housed in a 24-pin QFN package and functions within an ambient temperature range of -40°C to +105°C.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'AI' corresponds to industrial temperature grade (-40°C to +105°C) and tape/reel packaging as indicated by the 'T'. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply voltage requirements match the target system design.

Clock Buffers, Drivers Selection Notes

Select this component when low additive jitter and multi-output distribution are required. The device supports flexible input signaling formats including differential and single-ended sources. Output voltage levels can be adjusted via the VDDO supply to interface with various receiver logic families. Ensure input slew rate exceeds 2 V/ns for optimal noise performance.

Clock Buffers, Drivers Part Context

The SiT92113 belongs to SiTime's family of MEMS-based timing solutions. Unlike traditional quartz devices, these components offer programmability and robustness against shock and vibration. The AI-T designation indicates the industrial temperature variant packaged in a reel for surface-mount assembly.
