LMK04828SNKDTEP

The LMK04828SNKDTEP from Texas Instruments is an ultra low-noise, JESD204B compliant clock jitter cleaner designed for demanding timing applications. This device features 3 input channels and can generate up to 14 differential device clocks from PLL2, along with up to 7 SYSREF clocks. It supports a maximum output frequency of 3.2 GHz and offers various output types including LVDS, LVPECL, HSDS, and LCPECL.

With an operating temperature range of -55°C to 105°C, the LMK04828SNKDTEP is suitable for extended temperature environments. It boasts ultra-low RMS jitter performance, with figures as low as 88-fs (12 kHz to 20 MHz) and 91-fs (100 Hz to 20 MHz), and a noise floor of -162.5 dBc/Hz at 245.76 MHz. The device operates from a 3.15-V to 3.45-V supply.

Packaged in a 64-pin WQFN with an exposed pad, measuring 9 mm x 9 mm, this component is designed for surface mount applications. It utilizes a Dual Loop PLLatinum™ PLL Architecture and supports multi-mode operation including Dual PLL, Single PLL, and Clock Distribution. Features like hitless switching, loss of signal (LOS) detection, and holdover mode when input clocks are lost enhance its reliability.
