SIT92113AI-X

Clock Buffers, Drivers Overview

The SiT92113AI-X is a 5-output ultra-low jitter LVCMOS fan-out buffer designed for high-frequency clock distribution. It features additive jitter of 50 fs RMS and typical output skew of 30 ps. The device accepts inputs from primary, secondary, or crystal sources, supporting LVPECL, LVDS, LVCMOS, SSTL, HCSL, and OSC waveforms. It operates with independent core (VDD) and output (VDDO) supplies ranging from 1.5 V to 3.465 V. Maximum input frequency is 250 MHz, while the crystal input supports up to 50 MHz. The component is housed in a 24-pin QFN package.

Clock Buffers, Drivers Procurement Notes

Verify the 'X' suffix against official documentation to confirm specific tape-and-reel packaging or revision details. Ensure compatibility with required supply voltages and input signal types before integration.

Clock Buffers, Drivers Selection Notes

Select based on required output count (5 outputs) and input format compatibility (LVPECL, LVDS, etc.). Consider power supply requirements for both core and output domains to meet system voltage levels.

Clock Buffers, Drivers Part Context

The SiT92113 belongs to SiTime's family of low-jitter clock buffers. It provides differential-to-LVCMOS conversion and clock distribution capabilities for demanding digital systems requiring precise timing synchronization.
