LMK04228NKDT Description

Short technical summary and product information.

The LMK04228NKDT from Texas Instruments is a high-performance clock jitter cleaner designed for demanding timing applications. It utilizes a dual-loop PLLatinum™ architecture to achieve ultra-low noise performance, with an RMS jitter of just 156 fs.

 

This device supports input frequencies from LVCMOS, LVDS, and LVPECL sources and can generate up to 15 outputs. The output types include LVCMOS, LVDS, and LVPECL, with programmable frequencies ranging from 0.315 MHz to 1.25 GHz. It features JESD204B compliance, making it suitable for high-speed data converter clocking.

 

The LMK04228NKDT operates over an industrial temperature range of -40°C to 85°C and requires a supply voltage between 3.15V and 3.45V. It is available in a 64-pin WQFN package, designed for surface mounting.

 

Key electrical specifications include 3 input channels and 15 output channels, with a typical RMS jitter of 156 fs. The device also boasts a noise floor of -162.5 dBc/Hz at 245.76 MHz and a PLL2 normalized noise floor of -224 dBc/Hz.
