Application Field

The PL902153USY-T5 is typically used in consumer and desktop devices and is suitable for use in applications requiring a low cost, low power frequency synthesizer and clock generator. Typical applications include notebook computers, desktop computers, and embedded systems. The device is also suitable in applications requiring the highest level of accuracy and frequency stability such as communications, high-definition multimedia interface (HDMI), digital audio, and other low jitter requirements.

The PL902153USY-T5 is also suitable for use in applications such as networking, where demand is particularly high for power efficient and ultra-high clock frequency accuracy.

Working Principle

The PL902153USY-T5 utilizes a combination of phase-locked loops (PLLs) and voltage controlled oscillator (VCO) to generate a highly accurate and stable clock output. The PLLs are designed to ensure that the frequency accuracy is within 1ppm of the desired frequency. The single ended input (SIN) provides the source clock inputs to the PLLs, and the multiple frequency outputs from the VCO (VCO1, VCO2, VCO3 and VCO4) can be configured through the SIN input to support any input frequency.

In addition to the SIN input, the PL902153USY-T5 also provides two differential reference clock inputs, REFCLK1 and REFCLK2, that can be used to increase the clock accuracy. The PLLs can be programmed for any frequency range from 1MHz to 250MHz. The PLLs also feature programmable charge pump current, direct access enable, output slew rate and selectable divisions.

The PL902153USY-T5 also features a jitter attenuator and spread spectrum modulation that ensures the clock frequency is not affected by environmental noise. The jitter attenuator works by passing the clock frequency through a low-pass filter, which reduces the frequency jitter by suppressing high frequency noise components. The spread spectrum modulation is employed to further reduce the sensitivity of the device to noise and temperature changes.

In addition to the clock generator function, the PL902153USY-T5 includes a wide input/output range that supports standard and differential inputs, as well as differential output formats. The device also includes a low power design and minimal noise emission, which makes it suitable for low power applications.

The PL902153USY-T5 is a capable and versatile clock generator and frequency synthesizer for the consumer, desktop and laptop markets. With its high level of accuracy and stability, low power design and wide input/output range, the device provides an excellent solution for those requiring the highest frequency stability and accuracy.
