CDCLVP111MVFREP Application Field and Working Principle

CDCLVP111MVFREP is a type of clock buffer, driver, and gater, also called clock regeneration devices, which are important components in digital circuits. It is suitable for short haul or trace-length clock distribution applications. It comes with enable, skew control, and output voltage selection (1.8V, 2.5V, and 3.3V) that make it an ideal choice for microprocessor or ASIC applications.

Application Field

CDCLVP111MVFREP has multiple applications, including the following:

• Latchup protected LVPECL drive
• Data synchronization
• Synchronous memory
• Gigabit Ethernet
• Chip to chip communication
• High speed clock signal buffering

CDCLVP111MVFREP is especially suitable for signal buffering of fast edge rates, and can be used to drive multiple levels of signal trace clocks, minimizing clock skew between register within a synchronous digital design. It can also be used to reduce EMI/RFI emissions, spread spectrum devices can be used in combination with CDCLVP111MVFREP in designs where EMI/RFI is an issue.

Working Principle

CDCLVP111MVFREP utilizes different clock input levels (LVPECL, LVDS, HCSL) for different clock inputs, and also provides a selectable output voltage level (1.8V/2.5V/3.3V). This makes it very useful for distributed systems because it eliminates the need for level shifters and maintains low-skew regardless of the clock input level.

The simple internal circuitry of CDCLVP111MVFREP consists of the clock input stage (w/ optional differential termination resistors), a curve adjustment stage (which informs the driver how to drive the selected clock output ), a low-power output buffer stage (which is used to isolate the clock input to the actual output stage of the device ), and the output stage (which is used to amplify the clock signal as it transitions between the board lands and transmit the clock signal through the routing layer ).

CDCLVP111MVFREP clock buffer can also be used for clock recovery applications. The clock recovery technique is a method used to recover a clock signal from a digital data stream. In this type of application, a clock signal is recovered from the digital data stream by sampling the data stream at the time when the input clock would transition from one logic level to the other. The existing clock pulse is then divided down and used to create a new clock signal. This new clock is then used as a clocking source for the system.

In summary, CDCLVP111MVFREP is a type of clock buffer or driver, which is suitable for short haul or trace-length clock distribution applications. It has multiple applications, including data synchronization, chip to chip communication and high speed clock signal buffering. In addition, it can also be used for clock recovery applications. Therefore, it is a useful device for distributed systems.
