TILMK04828BISQ/NOPB
Overview
The LMK04828BISQ/NOPB is a high-performance clock jitter cleaner and generator designed for high-speed data converter clocking. It features two integrated Phase-Locked Loops (PLLs) and can generate up to 14 clock outputs with frequencies reaching 3.08GHz. The device is specifically architected to support JESD204B subclass 1 timing requirements for clocking high-speed ADCs and DACs.
Why Choose This Part
The LMK04828 offers industry-leading jitter performance, typically below 100fs RMS, which is essential for maintaining the SNR of high-speed data converters. Its dual-loop architecture allows for effective jitter cleaning of a noisy reference clock while providing flexible frequency synthesis. The integration of 14 outputs in a single 64-WQFN package reduces PCB area and simplifies complex clock tree designs.
Applications
Key Specifications
Getting Started
Engineers should use the TI Clock Design Tool or TICS Pro software to calculate register settings and simulate phase noise performance. For hardware evaluation, the LMK04828BEVM evaluation module provides a proven layout and SMA connectors for direct measurement. Configuration is handled via a 3-wire or 4-wire SPI interface to program the internal registers.
