LMK04208NKDT TI Clock Jitter Cleaner | 64-WQFN (9x9) | Dual PLL, 14 Outputs

Product Overview

The LMK04208NKDT is a high-performance clock jitter cleaner and frequency synthesizer from Texas Instruments, designed for demanding applications requiring ultra-low phase noise and precise frequency synthesis. It integrates dual PLLs (Phase-Locked Loops) with a voltage-controlled oscillator (VCO) and provides up to 14 differential or LVCMOS outputs. The device operates from a 3.3V supply and is housed in a compact 64-pin WQFN (9x9 mm) package.

Detailed Technical Specifications

Key Features

• Dual PLL architecture with integrated VCO for jitter cleaning and frequency synthesis
• Ultra-low RMS jitter (0.1 ps typical) for high-speed data converters
• 14 programmable outputs supporting LVDS, LVPECL, HCSL, and LVCMOS
• Digital delay and phase adjustment per output
• Holdover mode for holdover during reference loss
• SPI interface for configuration
• On-chip LDOs for improved PSRR

Target Applications

• 5G base stations (e.g., clock distribution for massive MIMO transceivers)
• Wireless infrastructure (e.g., remote radio units, small cells)
