LMK00105SQX/NOPB Description

Short technical summary and product information.

The LMK00105SQX/NOPB from Texas Instruments is an ultra-low jitter LVCMOS fanout buffer designed to distribute five clocks with minimal noise. It supports a universal input, accepting signals such as LVPECL, LVDS, HCSL, SSTL, LVCMOS, LVTTL, and crystal oscillators.

 

This buffer operates with a core supply voltage of 2.5V or 3.3V and offers adjustable output supply voltages from 1.5V to 3.3V for each bank. It can distribute clocks up to 200 MHz with an additive RMS jitter of typically 30 fs. The output skew is a low 25 ps, making it suitable for high-speed applications.

 

Designed for surface mounting, the LMK00105SQX/NOPB comes in a 24-WQFN (4x4 mm) package. Its operating temperature range is -40°C to 85°C. The device supports synchronous output enable for glitch-free operation and is well-suited for networking, telecom, server, and test equipment applications.

 

Key electrical specifications include 5 LVCMOS outputs, a universal input supporting multiple signal types, and a maximum frequency of 200 MHz. The core voltage can be 2.5V or 3.3V, with output voltages adjustable from 1.5V to 3.3V.
