The SY100EP15VK4G is a high-performance, low-power clock buffer that is suitable for a wide range of applications and for driving multiple clocks. It is based on the “EP15” process, a high-voltage 0.35-micron CMOS with backside ground plane technology, resulting in outstanding interconnection and packaging performance. This product is widely used in the following applications:

Clock Network Systems

The SY100EP15VK4G is designed to meet the needs of clock network systems, where it serves as the interface between a high-precision master clock source and multiple subsidiary clock outputs. The device comprises two digital PLLs (DPLLs), two all-digital phase-locked loops (ADPLLs) and four clock outputs. The DPLLs are responsible for accurately and reliably generating enhanced, low jitter clock outputs for subsystems. The ADPLLs enable up to 1-second holdover from the master clock if changes occur in the reference signal. The four clock outputs provide a wide range of frequency, duty-cycle and offset adjustments. This ensures that clocking signals are always properly synchronized and accurate in the system.

PLL Applications

The SY100EP15VK4G is suitable for PLL applications such as clock synthesis and distributed clocking systems. It provides an input and output range of up to 320 MHz in single-ended and differential modes, allowing these clocks to serve as generate-and-hold (GH) and polling systems. Furthermore, these clocks can output data up to and including the reference signal frequency. The device can also be used for generating fast and accurate clock signals that can be used to generate and synthesize multiple precision clock signals.

Embedded Systems

The SY100EP15VK4G is also suitable for embedded systems where its integrated switched-capacitor array (SCA) architecture eliminates the need for external components, and helps to lower the overall power consumption. Its integrated DPLLs and ADPLLs also help to simplify the clock network and further reduce system power consumption. Its wide frequency range and reduced power consumption make this product extremely suitable for embedded systems.

Working Principle

The SY100EP15VK4G consists of two DPLLs, two ADPLLs and four clock outputs. The DPLLs use phase-locked loop (PLL) technology to accurately and reliably replicate the reference clock. The ADPLLs help to ensure a constant holdover from the reference signal by producing an accurate output clock signal frequencies even in the event of sudden changes in the input reference signal. The four clock outputs are fully adjustable in terms of frequency, duty-cycle and offset adjustments. This enables the clocking signals to be accurately and reliably synchronized. The device also includes an integrated switched capacitor array to reduce power consumption.

Conclusion

The SY100EP15VK4G is an ideal clock buffer for clock network systems, PLL applications, and embedded systems. Its digital PLLs and ADPLLs help to provide highly accurate, low jitter clock outputs that are perfect for generating and synthesizing multiple precision clock signals, while its integrated SCA helps to reduce system power consumption. Furthermore, the device’s wide range of frequency and duty-cycle adjustments enable clocking signals to be accurately synchronized. With its versatile features and impressive performance, the SY100EP15VK4G is an excellent choice for multiple clock output applications.
