Clock/Timing - Clock Buffers, Drivers can be classified as a family of electronics components that serve as the interface for receiving and delivering clock signals in circuits. One special member of this family is the CY7B991V-2JC, which integrates a selectable low-pass filter, a 3.3V to 5V level translator, and a voltage translator. Let’s explore the application field and working principle of the CY7B991V-2JC.

Application fields of the CY7B991V-2JC:

• A global system for mobile communications (GSM) base station power.
• Devices used to drive LCDs, such as in cell phones and digital cameras.
• Frequency synthesizers in digital radios.
• Clock signal buffers in PC/Mac motherboards.

The working principle of the CY7B991V-2JC is based on its features and functions.

First of all, the CY7B991V-2JC includes a selectable low-pass filter which can limit the EMI and reduce the interference it generates to other components. This feature allows for improved signal integrity and timing constraints in high-frequency applications, leading to an optimal performance. It also possesses a power-on reset which helps to ensure that the device initialization is properly and orderly executed. This prevents unexpected operations in the system, and helps to prevent damage.

The CY7B991V-2JC also includes a 3.3V to 5V level translator, which is helpful for meeting certain voltage requirements from different components. The level translator helps to ensure that the correct logic level is inputted and outputted when operating in a 3.3V or 5V environment. This is especially useful when establishing a bi-directional connection with different devices.

The CY7B991V-2JC furthermore comes with a built-in oscillator and features a user-adjustable slew rate. This makes the device highly suitable for applications with specific timing requirements, such as frequency synthesizers in VCOs and digital radios. The user-adjustable slew rate further allows users to save power by providing flexibility in setting up the required clock frequency and operating voltage.

In summary, the CY7B991V-2JC is suitable for applications requiring a high-performance level and improved signal integrity in a variety of environments, such as GSM base stations, LCDs, frequency synthesizers, and clock signal buffers. It has features such as a selectable low-pass filter, 3.3V to 5V level translator, power-on reset, built-in oscillator, and user-adjustable slew rate, that all allow to reduce the interference generated by the device and save power.
