LMK04208NKDR Description

Short technical summary and product information.

The LMK04208NKDR from Texas Instruments is an advanced clock jitter cleaner designed for high-performance timing applications. It utilizes a Dual Loop PLLatinum™ PLL Architecture to achieve ultra-low RMS jitter, measuring as low as 111 fs (12 kHz to 20 MHz).

This device supports a wide output frequency range from 0.329 MHz to 3072 MHz, with flexible output types including LVCMOS, LVDS, and LVPECL. It features two redundant input clocks with loss-of-signal (LOS) detection and automatic switch-over modes. The LMK04208NKDR includes integrated low-noise crystal oscillator circuitry and can operate in holdover mode when input clocks are lost.

Packaged in a 64-pin WQFN (9 mm x 9 mm), the LMK04208NKDR is designed for surface mount applications. It operates within an industrial temperature range of -40°C to +85°C and requires a supply voltage between 3.15V and 3.45V. The device offers multiple operating modes, including Dual PLL, Single PLL, and Clock Distribution, making it suitable for various system synchronization needs.
