The SY58052UMI is a fully-integrated Clock Generator/Module for cellular and other high-speed communications applications. It is a high-performance, low noise, low-power solution for generating low-jitter clocks from common reference signals. It is designed for 3G/4G LTE applications and provides the highest degree of flexibility and performance for both mobile and fixed application.

The SY58052UMI is designed to synchronize two independent reference signals to a common data rate. It can achieve a maximum jitter less than +/-50ps for periodic signals and +/-150ps for non-periodic signals. The user has the option to configure the output to sync both reference clocks, or to generate separate phase-locked loop (PLL) outputs. The Output clocks can be phase adjusted up to +/-360 degrees.

The SY58052UMI is based on an advanced analog phase-locked loop architecture which allows it to achieve low jitter performance while being implemented in small form factors. It feature a narrow bandwidth of 500MHz, a low noise VCO, a low jitter 2x PLL and an integrated loop filter.

The main functions of the SY58052UMI are as follows:

• Synchronizing two independent clock sources using a PLL circuit.
• Adjusting clock phase from 90 to 180 degrees.
• Providing low pass noise filtering in the output clocks.
• Generating two PLL outputs for high frequency clocks.

The SY58052UMI offers high performance clock synchronization from multiple reference sources by using a low noise VCO, allowing for low jitter performance in high-bandwidth applications. It also provides flexible phase control and output frequency range, allowing it to be used in various applications. Additionally, it features integrated loop filter and optical isolation, further improving its performance over a wide temperature range.

The working principle of the SY58052UMI is to convert a low frequency input clock, typically between 20MHz and 150MHz, to a higher frequency output of 1.5GHz. The device achieves this by synthesizing the high frequency clock from the low frequency reference clock. To do this, the low frequency reference clock is converted to a higher frequency through a PLL circuit and is then fed back into the VCO. In this way, the PLL circuit can control the output frequency of the VCO. This is a continuous closed loop process and the user can adjust the frequency of the output clock by changing the PLL settings and gain factor.

The SY58052UMI can be applied to a wide range of mobile and fixed telecommunications applications such as cellular phones, GSM, CDMA, and wireless LANs. It is also ideal for use in communication systems that require low jitter and high frequency clocks. Moreover, the minimal form factor and low power consumption makes it suitable for portable and handheld devices.

In conclusion, the SY58052UMI is a highly advanced clock/module designed for a variety of applications in mobile and fixed telecommunication systems. It is capable of delivering low jitter clocks from two independent reference signals. It is easy to configure and provides adjustable phase and frequency control. Additionally, its small form factor and low power consumption make it ideal for the consumer and mobile market.
