The 849N202CKI-017LF belongs to the Clock/Timing - Clock Generators, PLLs, and Frequency Synthesizerscategory. Many consider this device to be a high-performance programmable clock generator, and itsapplications involve a range of usage scenarios, including media servers, audio and video servers,computer systems, and communication equipment. This device has a wide programmable input frequencyrange of 4MHz to 250MHz, can support eight clock output frequencies of up to 150Mhz, and featureslow power consumption. Dual buffer architectures and digital lock technologies enable jitter operationsdown to 10ps RMS.Before delving into the device’s particulars, it is important to understand its working principles. Thisclock generates precise timing, frequency and phase control, as well as clock synchronization, from asingle reference clock, usually an external crystal oscillator or clock signal. This is done by generatingeight independent clock outputs with variable frequencies and clock ratios, while ensuring the precisephase and frequency alignment of the outputs relative to the reference clock. This precise timed outputcontrol ensures continuity and synchronization of the clock sources within many types of systemapplications.The outer housing of the 849N202CKI-017LF is made of plastic, and has a 5mm diameter, with TSSOP32package size. Its temperature range lays between -40 to 85 degrees celsius, and its supply voltage isbetween 3.0 to 3.6V DC. Its frequency range is from and 4MHz to 250MHz, and its individual clockoutput frequencies range from and 34MHz to 150MHz.The 849N202CKI-017LF’s internal clock chip technology is based on PLL (Phase Lock Loop) circuitarchitecture. A Phase Lock Loop is a very popular technique used to synchronize a system’s output withthe incoming signals from a reference clock. The reference clock is generally used to compare thedesired output and the system’s actual output, in order to regulate the system and output towards thedesired frequency. The 849N202CKI-017LF utilizes such technologies, in order to achieve precise clocksynchronization within a system.The internal clock generator of this device has the capability to generate 8 independent output clockswith jitter free, precise timing performance.
