PCK9456BD,157 Application Field and Working Principle

The PCK9456BD,157 is a Clock/Timing application device that is available in a variety of configurations. It is a clock buffer and driver that can be used in many different applications, ranging from simple timing reference to more complex applications requiring higher levels of accuracy.

The device is specifically designed for use in clock buffering and driving in media interfaces such as Serial ATA (SATA), USB, ExpressCard, and other serial interfaces. It can also be used as an IC for clock synchronization in applications such as frequency synthesis, digital logic, analog-to-digital converters, digital signal processing, and microprocessor clocking using either a Crystallizer or a synthesizer.

PCK9456BD, 157 is a low-power, clock/timing device. The underlying principle of operation is based on a differential circuit, where the two pins of the input signal are connected to the PCK9456BD,157 differentially. The device operates on a single voltage and can support a variety of input frequencies ranging from 2kHz up to 2GHz.

The PCK9456BD,157 is an inverting device, meaning that the output signal frequency is the inverse of the input signal frequency. It is designed to generate output signals with a precise frequency and phase shift compared to the input signals.

The PCK9456BD,157 utilizes CMOS technology and an adjustable terminated impedance circuit. It is composed of four stages of high-speed, low-power CMOS logic, including two multiplexers, single equalizer, and output buffer circuits. The differential input and output signals are routed to the two pairs of pins.

The differential input stage is designed to eliminate common mode noise and maximize signal integrity. The device can achieve low phase noise, low jitter, and low drive current, which make it ideal for use in clock and timing applications. The output is also adjustable, which allows it to be used in different start-up frequencies.

The automated self-calibration loop of the PCK9456BD,157 ensures that the frequency, phase shift, and amplitude of the output signals are accurately adjusted to the exact specifications of the input signals. This ensures that the accuracy and stability of the output signal is maintained over the entire operating temperature range and operating voltage range.

In summary, the PCK9456BD,157 is an ideal choice for clock buffering and driving in media interfaces. It provides low power consumption, low phase noise, low jitter, and adjustable frequency, making it suitable for a wide range of clock and timing applications.
