LMK00105SQ Description

Short technical summary and product information.

The LMK00105SQ from Texas Instruments is a high-performance, low-noise LVCMOS fanout buffer designed to distribute five ultra-low jitter clocks from a universal input. This buffer supports differential, single-ended, or crystal inputs and offers synchronous output enable for glitch-free operation.

 

Key electrical specifications include an additive RMS jitter of 30 fs, with core supply voltages of 2.5 V or 3.3 V. The output supply voltage is adjustable from 1.5 V to 3.3 V for each bank. The device operates within a temperature range of -40°C to 85°C and provides LVCMOS outputs up to 200 MHz.

 

Packaged in a 24-pin WQFN measuring 4 mm x 4 mm, the LMK00105SQ is well-suited for demanding applications such as networking, telecom, server and storage area networking, RRU LO reference distribution, medical, and test equipment. Its ultra low-skew, low-jitter, and high PSRR characteristics make it an excellent choice for clock distribution needs.
