TILMK00105SQ/NOPB
Overview
The LMK00105SQ/NOPB is a high-performance clock fanout buffer designed to distribute a single clock source to up to five LVCMOS outputs with minimal additive jitter. It features a versatile 2:5 input multiplexer that accepts a wide range of differential and single-ended signals, including a direct crystal oscillator interface. This IC serves as a precision translator and distributor for systems requiring low-noise clocking between 2.375V and 3.45V.
Why Choose This Part
It offers exceptional flexibility with a universal input stage that supports LVPECL, LVDS, HCSL, SSTL, and LVTTL without external termination in many cases. The device features a very low noise floor of -166 dBc/Hz and a synchronous output enable to ensure clock signals are started or stopped without generating fragments or glitches.
Applications
Key Specifications
Getting Started
Designers should prioritize low-impedance ground paths and place 0.1 uF bypass capacitors as close to the VDD and VDDO pins as possible. For evaluation, use the LMK00105EVM to test various input configurations and measure output skew. Ensure the 24-WFQFN thermal pad is soldered to a large ground plane to maintain an operating temperature within the -40 to +85 degree Celsius range.
