ADCLK925BCPZ-R2 Integrated Circuits (ICs)

ADCLK925BCPZ-R2 is a Clock and Timing device, particularly a Clock Buffer, Driver, and Generator. It meets the requirements for I2S and other formats for audio applications, as well as for video applications, such as flat panel displays. This high precision device integrates latch circuitry, ESD protection, as well as programmable glitch-free synchronization.

Applications

ADCLK925BCPZ-R2 is designed to generate multiple differential clock signals based on a single reference clock input. This device can also buffer one additional reference clock signal. It is often used in audio applications, such as the hi-fidelity audio systems, as well as digital video applications, such as flat panel displays, among others. It is also commonly found in devices related to optical digital and data communications.

Working Principle

The ADCLK925BCPZ-R2 is based on an oscillator whose reference clock is specified by an external crystal oscillator connected to the device’s on-chip oscillator control logic. The device can then generate multiple clock signals and can also buffer a single reference clock signal. The device offers adjustable differential outputs of 0–60% duty cycle with superb jitter performance to support most common video and audio formats.

The device has an innovative glitch free synchronization feature, which allows the device to synchronize at any point in time. This eliminates the need for additional retrimming of the output drivers for synchronization and ensures glitch free startup. The device is also able to detect and reject invalid signals, preserving the integrity of the output clock at all times. The device also has a capability to sense the presence of an active power supply, allowing the clock to remain active while other parts of the system power down.

The ADCLK925BCPZ-R2 also has several other features that provide system designers with flexibility over their clock and timing design. These include programmable setting of frequency, phase, and skew, as well as integrated ESD protection on all input and output signals. The device is also fabricated using low power CMOS process, which reduces power consumption and helps ensure the overall operation of the system.

Conclusion

The ADCLK925BCPZ-R2 is a high precision, low power, Clock and Timing device, specifically a Clock Buffer, Driver, and Generator. It is designed to provide multiple clock signals and buffer one reference clock signal. It is often used in audio and video applications, as well as optical digital and data communications. The device offers a wide range of features that provide system designers with flexibility and ease of use. The device also offers robust ESD protection and low power consumption, making it an ideal choice for a variety of clock and timing applications.
