The SI4114G-B-GM is a clock generator, PLL, or frequency synthesizer for a variety of applications. It can be used to generate any frequency from 1Hz to 4GHz in GSM/EDGE and LTE systems. The product’s timing performance is also well-suited for clocking and reference applications. There are also features such as on-chip phase-lock loop (PLL), phase-shift capability, and loop bandwidth to meet the challenging clock requirements of today’s applications.The SI4114G-B-GM is a frequency synthesizer that provides a wide range of frequency tuning which is capable of generating any frequency from 1Hz to 4GHz in GSM/EDGE and LTE systems. It features a built-in phase-locked loop (PLL) and phase-shift capability, as well as providing loop bandwidth for a variety of applications. This frequency synthesizer has a very small footprint making it suitable for a wide range of applications. The frequency range is from 1Hz to 4GHz in GSM/EDGE and LTE systems, with up to 800MHz wide-band tuning capabilities.The device is designed to be used with an external clock source such as an oven-controlled crystal oscillator (OCXO). The external clock source is used to provide a stable and accurate clock frequency to the device. The PLL is then able to transmit the required frequencies to the external output pins, to the device itself, or to other components in the system. Alternatively, the device can be used without an external clock source, in which case the device itself generates its own clock.The SI4114G-B-GM is also capable of providing a range of phase-shift capabilities. This includes the ability to shift the internal clock from any phase angle between 0° and 360°. This is achieved by choosing a phase-tracking source from a set of predefined phase-tracking sources, such as crystal oscillators or other signals of known phase accuracy. The phase-shift capability is particularly useful for application that require precise clocking, such as medical imaging and spectrum acquisition. The SI4114G-B-GM is also capable of providing the necessary loop bandwidth to maintain phase-lock. Depending on the application, the product can provide a loop bandwidth of up to 50MHz. This makes it suitable for a wide range of purposes, such as synchronizing multiple components in a system, or providing the necessary bandwidth to support advanced protocol requirements such as Bluetooth or Wi-Fi.In conclusion, the SI4114G-B-GM provides a highly accurate clock generator, PLL, and frequency synthesizer, which is suitable for a variety of applications, from clocking and reference purposes, to spectrum acquisition and communication requirements. The device has a wide range of frequency tuning capabilities, as well as phase-shift and loop bandwidth capabilities to maintain phase-lock. The small footprint of the device also makes it particularly suitable for use in a wide range of applications, making it an ideal choice for reliable and accurate clock generation and signal synchronization.
