The SI5350A-B03806-GTR is a high-performance, integrated, clock jitter attenuator from Silicon Laboratories. It features four ultra-low-jitter differential outputs, two differential reference inputs, and two LVDS inputs. The SI5350A-B03806-GTR supports up to 25.78MHz source, providing low-jitter output frequencies up to 1000MHz. The device provides great flexibility and options, allowing applications to be designed that use both clean deterministic signals, as well as cost-effective clock sources.

The SI5350A-B03806-GTR is ideal for architectural applications, such as digital video and video transport. It is also used in a wide range of applications, such as optical transport systems, industrial automation, and medical instrumentation. Other applications include Ethernet, T1/E1 multiplexers, routers, and any other system requiring a clean, synchronized clock.

The SI5350A-B03806-GTR clock jitter attenuator is designed to provide low jitter and clean balanced outputs. The jitter attenuation is achieved via a multi-stage, low-jitter, clock multiplication and divider circuit that segments the incoming reference clock into high-amplitude, low frequency. The jitter attenuation quality delivers superior performance compared to traditional clock synthesis techniques. The device also provides an integrated, programmable, digital zero delay buffer that operates from a 16MHz to 2000KHz frequency reference. This feature simplifies system layout and allows designers to eliminate the need for external clock for clocking sensitive logic.

The SI5350A-B03806-GTR clock jitter attenuator is designed for a wide range of frequency accuracy requirements. It is constructed with an advanced on-chip temperature compensation circuit that compensates for temperature variations. The device utilizes a protection circuit to detect over voltage, over current, and short circuit conditions. It also features a power-down mode and a programmable pull-up/pull-down resistor available on each of the outputs.

The working principle of the SI5350A-B03806-GTR clock jitter attenuator consists in using two differential reference clocks and two LVDS inputs. The reference clocks are fed through two LVDS channels, and these are then used to divide or multiply the frequency of the input signal. The signal is divided or multiplied until it reaches the desired frequency. The signal is then divided or multiplied depending on the application’s needs. Once the signal is at the desired frequency, the jitter is then attenuated by the device, resulting in a clean and precise output signal.

In summary, the SI5350A-B03806-GTR clock jitter attenuator from Silicon Laboratories is ideal for applications requiring synchronized, clean, and precise clock signals. It is suitable for a wide range of applications, from Ethernet, digital video, and industrial automation, to T1/E1 multiplexers, routers, and optical transport systems. The device utilizes advanced on-chip temperature compensation to provide superior performance, and a programmable zero delay buffer to simplify system layout. It also features integrated protection circuits to detect over voltage and over current. Finally, it is designed with an advanced multi-stage clock multiplication and divider circuit to attenuate jitter, providing low jitter, clean and balanced outputs.
