IDT49FCT3805BQ

Clock/Timing – Clock Buffers, Drivers are crucial components in any electronic or electrical system, as they are responsible to distribute the necessary clock signals which provides the reference point or timing for each of the sub systems or components in the overall system. IDT49FCT3805BQ is one such Buffers, Drivers which are designed to meet the applications that require low-skew data and clock port buffering. This article discusses the application fields and working principle of the IDT49FCT3805BQ.

The IDT49FCT3805BQ is an advanced low output impedance 5-bit bus-hold register-buffers with 3-state outputs. This particular design offers low output Skew (50ps max) along with full On-Demand Bus Hold Logic. This particular Buffers, Drivers from the IDT family of buffers has various applications like Fan-Out Buffering for multi-drop systems, Clock Distribution, Data Distribution for synchronous Interface Buses, Load activated Switching and Timing Generation.

In its application as a Fan-Out Buffer, the IDT49FCT3805BQ is ideal when the device is being used to drive a bus line off of a single source or port. This Buffers, Drivers provides low output impedance, which helps to improve the loading characteristics of the bus line. As the bus line is buffered, it automatically reduces the effects of ground bounce and noise, thus improving the overall data integrity in the system. The On-Demand Bus Hold feature enables the input data to be held when the output enable pin is in the active mode, thereby further increasing the rise and fall times of the signaled output.

The IDT49FCT3805BQ is also suitable for timing generation applications, as it provides clock synchronization. This particular feature is achieved by the fact that the outputs data from the bus-hold flip-flops get synchronized with the input data. Also, the outputs of the IDT49FCT3805BQ drive the input of the subsequent clock latch, thus providing the necessary time delay for synchronization.

The IDT49FCT3805BQ Buffer is also used as Load Activated Switching, as they support very low On Resistance levels, and are ideal to be used in systems which require high driving capabilities. The use of such load activated switches helps to reduce power consumption as well as improve the overall switching performance of such systems.

The working principle of the IDT49FCT3805BQ is quite simple. As the data is fed in to the Input pins of the buffer, it gets stored in the internal registers which gets regulated by the input control signal. As the data is fed to the internal registers it gets latched, and the registered data gets transmitted to the output pins only when the Control signal is in the active state. The Data flow in such a scenario, is from left to right. This complete mechanism is regulated by the clock signals present in the system, which should be of such nature that it should produce a non-overlapping data and clock signals throughout the Data flow.

In summary, the IDT49FCT3805BQ is a robust and reliable buffer, driver and clock synchronization device, that can be used in a variety of applications like Fan-Out Buffering, Clock Distribution, Load activated Switching and Timing Generation. The device is capable of providing low output impedance and low output skew, which improves the overall performance of the system and reduces power consumption.
