Clock Generators, PLLs, Frequency Synthesizers

The LMK03000ISQ/NOPB is a precision frequency synthesizer and clock generator, ideal for applications requiring precise clock generation and synchronization for digital video, broadcast and telecommunications systems. It features a precise 10-phase phase locked loop (PLL) design, providing phase and frequency lock in digital systems. The device generates 20 sets of phase-locked clock outputs and clock product pairs from each input clock frequency, making it suitable for a wide range of applications including Digital Video Broadcasting (DVB), broadcast audio, professional audio, and other communications systems.

The LMK03000ISQ/NOPB is designed to meet the needs of high-performance and high-resolution applications. It offers improved power efficiency, low power consumption, and fast switching times. It is highly accurate, providing clock jitter levels as low as 10MHz and operating frequencies up to 200MHz. It offers adjustable clock output parameters to meet diverse system requirements and supports a wide range of clock formats, including Non-Return 0 (NRZ), Return to Zero (RZ), Bi-Phase, SCLK, and CMOS.

TheLMK03000ISQ/NOPB features three main operational functions for clock generation: Frequency Synthesizing, Phase Locked Looping and Clock Generation. The Frequency Synthesizing function enables the device to synthesize different output frequencies from an input clock frequency. The device utilizes a 10-phase PLL to produce a PLL signal which is used to generate an output frequency. The Phase Locked Looping function determines the reference clock frequency from a programmed reference clock signal. The device locks onto the reference frequency and advances or retards its frequency as needed for synchronization with the reference clock. The Clock Generation function generates the output clocks required to support the selected clock format. The device supports a variety of frequency synthesis modes, including fractional-N and interpolation.

TheLMK03000ISQ/NOPB is ideal for a range of clock and signal generation needs, including Video on Demand (VoD), Cellular Base Station (CBS) networks, and broadcast audio/video. It is also suitable for communications systems requiring precision synchronization, such as GSM, TDMA, and IEEE 802.11-based networks. The device provides high accuracy, low power consumption, and fast switching times, making it well suited for implantation in digital video, broadcast and communications systems.
