Clock and timing systems provide the basic functions necessary for controlling microprocessors, and their reliability and accuracy are critical for synchronized operations. The SY89420VJC-TR is a highly reliable high-performance, low-jitter, low-power clock synthesizer designed to meet the requirements of such applications. The device incorporates several innovative and advanced features that enable high-precision clock and timing signals at frequencies up to 400MHz.

The SY89420VJC-TR is suitable for a variety of clock, data and communications systems, as it is compatible with a variety of popular multi-pole IC packages. It can be used in BGA (Ball Grid Array) packages, as well as in application-specific IC (ASIC) packages, making it an excellent choice for any type of clock and timing system.

The SY89420VJC-TR operates over a wide supply voltage (1.8V to 5.5V) and an extended temperature range (–40°C to +105°C). It also boasts an ultra-low clock skew and jitter (1ps), allowing it to be used in applications requiring very low noise, such as in communications and data-acquisition circuits.

The SY89420VJC-TR supports a wide range of output frequencies, making it an ideal solution for any type of clock and timing system. The device operates through a highly accurate voltage-controlled oscillator (VCO), which delivers precise frequency outputs of up to 400MHz. Its flexible output, low jitter and low power consumption makes it ideal for a variety of designs requiring low skew clock signals.

Working Principle:
The SY89420VJC-TR integrates various components to ensure accurate and stable operation. It includes a low-jitter VCO, a clock generator, and a PLL circuit to compensate for any variations in the output frequency, enabling the output signal to maintain its stability and accuracy. The VCO generates a signal at a programmed frequency, which is then sent to the clock generator, where it is further processed and divided into different frequencies as per the program. The output frequencies from the clock generator are sent to the PLL, which compensates for any phase or frequency shifts. The output signals from the PLL are then fed to the output drivers for distribution to other devices.

The SY89420VJC-TR’s combination of integrated components helps ensure accuracy and reliability at very low power consumption. The device also provides functional diagnostic and telecoms features, such as a low-skew reset input, as well as features that support open-drain output, jitter attenuation, and frequency sweep control.

The SY89420VJC-TR is an excellent choice for any application that requires precision clock and timing signals, as the device offers unmatched reliability, accuracy and low power consumption. The SY89420VJC-TR can be used in a variety of clock and timing systems, such as those used in communications and data-processing applications, as well as in consumer electronics, automotive, and other applications.
