CDCVF310PWR Application Field and Working Principle

The CDCVF310PWR is a 5-bit delay line buffer that bridgesthe gap between high-performance, low-cost timing solutions. This efficiently designedclock buffer provides connectivity between high-speed timing sources and sinks. The device operates from 3 V to 3.6 V and can handle maximum clock inputs up to 400 MHz.

The clock buffer is used forclock fanning−out, skew management and clock bus distribution applications. It provides low skew outputs from a common input clock and is available in a wide variety of configurations.CDCVF310PWR is ideal for applications that require the most stringent skew managementwith low power requirements.

The device is suitable for typical clock bus, source-synchronous interface, implementation of Ethernet MAC or similar applications. It is also suitable for clock distribution in PCBs, control planes and FPGA applications. Furthermore, the device is designed to reduce noise and glitches in the clock and is able to support single-ended, differential and bar output scenarios.

Working Principle:

The CDCVF310PWR consists of five identical stages ofdelay cells (programmed in the factory to achieve timing performance specifications).Each internal delay cell consists of two inverting buffers and three metal-oxide semiconductor (MOS) transistors. Each cell also includes an input latch, which enables low skew clock fanning-out by capture and hold of the rising/falling edges of the clock input signals.Thedevice is able to provide a wide range of frequencies at both normal and low-power conditions.

The duration of each delay stage is programmable, allowing the user to adjust the delay lines for a specific set of conditions. This enables low-skew buffering for a wide range of frequencies and power levels, thus providing superior performance compared to conventional clock buffer products.The clock output is available in both single-ended and differential output formats, allowing flexibility in controlling the data and clock signals.

The CDCVF310PWR also features active power-down modes, allowing the user to switch between normal and low-power modes without any interruptions in the clock signals. This feature reduces the overall power consumption and consequently makes the device suitable for low-power applications.

The CDCVF310PWR clock buffer operates in either the normal or the power-down modes, and is available in a wide range of output configurations. The user can customize the device to suit the specific needs and timing requirements of their application. The device is able to handle maximum clock speeds of up to 400 MHz, and is suitable for both single-ended and differential output formats.

In summary, the CDCVF310PWR is an excellent, low-cost solution for clock distribution, skew management and clock fanning−out applications. It provides superior clock performance and can handle demanding frequency requirements. The device is available in a wide range of output configurations and offers active power-down modes, making it suitable for a variety of low-power applications.
