The SI5344H-C05141-GMR is a high-performance, low-power, low-jitter clock generator, which utilizes Silicon Laboratories’ 3rd generation of any-frequency, any-output clock technology. This device can generate up to eight outputs in both LVPECL, LVDS, and SSTL formats with frequencies up to 400MHz. It is designed to operate from an inexpensive clock reference crystal ranging from 10MHz to 50MHz, as well as can be used to serve multiple applications.

The SI5344H-C05141-GMR offers double and low jitter performance, normally associated with much more expensive and power-hungry devices. The device’s 3rd generation-Any-Frequency technology utilizes a Programmable Frequency Scaling Algorithm (PFSA) that allows for the generation of any frequency from any starting frequency, providing unsurpassed flexibility and ease of use. This algorithm enables designers to choose the most cost-effective crystal and still realize truly any frequency of operation.

The SI5344H-C05141-GMR allows for extremely low-power operation without compromising on performance. It has 4 adjustable, 2 fixed 1.2V PLLs with an extremely low-power power-down mode, allowing the device to consume less than 10µA in power-down. Additionally, excellent noise and jitter rejection further reduce total power consumption. This makes the device ideal for battery-powered and portable applications.

The SI5344H-C05141-GMR can be widely used in two main application fields. Firstly, the device is widely used in telecom, data and computing applications, especially for clock synchronization and clock convergence in servers, routers, and base stations. These applications require low jitter and high-frequency accuracy and long term stability. Secondly, the device can be used in consumer electronics, especially TV and multimedia devices which require a multitude of clock formats and frequencies, and quite often extremely low power consumption.

The SI5344H-C05141-GMR device works by using a combination of 3rd generation algorithms and hardware based on a digital clock driver design. An incoming crystal oscillator reference is connected to the device and its frequency is used as the main frequency reference. The PFSA algorithm then distributes this reference to several clock inputs. Several clock outputs are then realized thanks to internal low-jitter, low-power fractional-N frequency synthesizers to generate accurate, low phase-noise outputs from multiple reference frequencies.

Overall, the SI5344H-C05141-GMR is a powerful and flexible device for clock generators, PLLs, and frequency synthesizers. The device can synthesize multiple clock outputs of any frequency from a single reference crystal oscillator with an extremely low-power consumption. It is ideal for telecom, data, computing, and consumer electronic applications, where a wide range of frequencies, accuracy, and low jitter are required.
