A clock synthesizer is an integrated circuit, designed to provide an electrical signal that is both accurate and stable. The SI5344A-B-GM is a low-jitter clock synthesizer that is designed for wireless, wireline, and computing applications. It is capable of generating up to five clocks from a single input reference frequency, and can also generate clock signals with a wide range of frequencies—from under 1MHz to over 600MHz—using only minimal power. This makes the SI5344A-B-GM a versatile choice for a range of applications.

The SI5344A-B-GM is able to output clocks signals with a jitter typical of 200fs rms and a phase noise of -170dBc/Hz @ 10KHz. This makes it ideal for applications such as 5G base station radio, radio frequency (RF) front-end, and synchronous Ethernet (SyncE). It is also suitable for PC genlock applications and time-of-flight (TOF) systems. Furthermore, it can also be used in standards-compliant clocking systems, such as I2C and SMBus, as well as SONET and 100BASE-T Ethernet.

The SI5344A-B-GM is designed around a multi-PLL architecture with a single low-jitter input reference oscillator, allowing for accurate clock generation. It works by multiplying or dividing the frequency of the oscillator by one of the various ratios available through the chip’s on-board phase-locked loop (PLL) circuit. The clock generator also features two independent phase-switched loops (PSLs) that can be used to adjust the phase of the output clocks, as well as two programmable delay lines that can be used to spread the frequency spectrum of the output clocks.

The SI5344A-B-GM is a highly efficient, low-power device, making it ideal for battery-powered wireless applications such as wireless sensor networks and wearable devices. The chip integrates an on-board LDO regulator, allowing it to operate in low-voltage and ultra-low-power applications. The silicon process used in the chip also enables the chip to work in severe temperature environments.

The SI5344A-B-GM offers a wide variety of features, including an input/output buffer and spread spectrum support, as well as a multitude of system features. It also comes equipped with an on-board temperature sensor and power-saving modes that include sleep, STOP, and START modes. Additionally, the chip supports both single-ended and differential inputs and outputs, making it ideal for a range of applications.
