Other applications such as optical networking, data communications, digital broadcasting, and video/audio streaming, require a high-performance, low-phase noise and low-jitter clock source for proper operation. The 843207CY-350LFT fits these applications perfectly being capable of providing both high-frequency and low-frequency clock generation from one cost-effective solution.

Working Principle

The 843207CY-350LFT utilizes an embedded PLL to generate the various output signals, allowing it to cover a wide frequency range. It can generate an output clock frequency from 50 KHz up to 350 MHz, with a wide selection of predetermined output frequencies available. The device can also handle complex, multirate clock networks with multiple data rates and operating frequencies, making it possible to scale and optimize the output clocks according to the needs of each system application.

Once a frequency is selected, the 843207CY-350LFT uses a digital phase-locked loops (PLLs) to lock the output frequency to a stable reference clock. This ensures that the output clock remains consistently accurate and free from the output jitter and noise that often accompany standard clock sources. The device also includes an internal on-chip voltage-controlled oscillator (VCO) to minimize noise and jitter on the output, making the 843207CY-350LFT an ideal choice for most applications that require a low-noise and low-jitter clock source.

In addition to controlling the output clock frequency, the 843207CY-350LFT also has configurable output enable conditions, allowing the output to be enabled only when needed. This can greatly improve power consumption and ease the design of power management and control logic. It also features low-noise internal outputs, making it easier to achieve highly accurate clocking performance.

The 843207CY-350LFT is also capable of frequency modulation and spread spectrum clocking, making it a versatile device for many different applications. It is also integrated with many other advanced features such as a built-in programmable dampening filter and digital frequency divider, allowing users to modify output frequencies in a wide range of conditions.

The 843207CY-350LFT is the ideal choice for a wide range of clock and timing applications. Its programmability, wide frequency range, and integrated features make it perfect for many different kinds of clock, timing, and frequency synthesis applications.
