SI5351A-B04943-GTR is a clock signal generator with a wide range of application fields and working principle. It is categorized under clock/timing-clock generators, PLLs, frequency synthesizers.The SI5351A-B04943-GTR is based on a highly integrated synthesizer providing four outputs and wide range of free-running frequency in the range of 8 kHz to 200 MHz. It uses a unique zero-delay buffer (ZDB) architecture and high performance, low-jitter output. The typical jitter is only 1 ps RMS. The devices offer integrated features such as a 25-bit numerically controlled oscillator (NCO), gating, 270-degree phase shift, user-controlled output driver slew rate. The SI5351A-B04943-GTR has a wide range of applications because it is highly flexible and supports different applications with ease. It is suitable for embedded systems and wireless communication systems, as well as consumer products, automotive, high-end clock applications, and telecom clocks. The device’s integrated output driver also makes it applicable for radio frequency (RF) signal generation.The SI5351A-B04943-GTR works by using a ZDB architecture. Its output generator is a complex ‘PLL’ that divides down two reference frequencies. The main frequency is generated on one output by multiplying or dividing the main reference frequency with a divider. The other outputs are generated by dividing down the other reference frequency according to the output frequency that is desired. The NCO provides a synthesized frequency range from 8 kHz to 200 MHz in integer or fractional divisions of the main reference or internal clock frequency.The device offers different operating modes. It has four operating modes: free-running mode (FRM), PLL mode (PLLM), high frequency reference counter mode (HFCM), and warm start-up mode (WSM). FRM provides the output frequency without any locking of an external reference signal. PLLM is used when the device is locked to an external reference signal. HFCM is an extended FRM in which the source clock can be changed during operation. Finally, WSM is used for burst operation.The SI5351A-B04943-GTR is a highly integrated device providing flexible clock signal generation for a wide range of applications. It has a wide range of applications areas with its output range from 8 kHz to 200 MHz and various modes of operation. It also offers a low-jitter output that improves the performance in applications such as embedded systems, telecom and RF signal generation.
