CDCVF857RHAT Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers by Texas Instruments

The CDCVF857RHAT is a high-performance, low-power CMOS (Complementary Metal-Oxide-Semiconductor) device manufactured by Texas Instruments. It is part of the CDC (Clock Domain Crossing) family of devices, which are designed to facilitate the transfer of signals between different clock domains in digital systems.

Key Features:

1. Functionality: The CDCVF857RHAT is a dual 2-input multiplexer (MUX) with a built-in clock signal. It allows for the selection of one of two input signals based on a control signal, making it ideal for applications that require signal routing and switching.

2. Voltage Levels: This device operates over a wide voltage range, typically from 1.65V to 5.5V, making it compatible with various logic levels. This flexibility allows it to be used in both low-voltage and standard voltage applications.

3. Propagation Delay: The CDCVF857RHAT features low propagation delays, which is crucial for high-speed applications. This ensures that the selected input signal is output with minimal latency, maintaining the integrity of high-frequency signals.

4. Power Consumption: Designed for low power consumption, the CDCVF857RHAT is suitable for battery-operated devices and applications where energy efficiency is a priority. It typically consumes very little static power, contributing to longer battery life in portable devices.

5. Temperature Range: The device is rated for operation over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications where environmental conditions can vary significantly.

6. Package Type: The CDCVF857RHAT is available in a compact HTQFP (Thin Quad Flat Package) format, which is advantageous for space-constrained designs. The small footprint allows for efficient PCB layout and design.

7. Applications: This device is commonly used in various applications, including data communication, signal processing, and interfacing between different digital systems. It is particularly useful in scenarios where clock domain crossing is necessary, such as in FPGA designs, microcontroller interfacing, and high-speed data acquisition systems.

Summary:

In summary, the CDCVF857RHAT from Texas Instruments is a versatile and efficient dual 2-input multiplexer designed for high-speed, low-power applications. Its ability to operate across a wide voltage range and temperature spectrum, combined with its low propagation delay and compact packaging, makes it an excellent choice for modern digital circuit designs that require reliable signal routing and clock domain management.
