(unit) picosecond - 10^-12 seconds. Jitter A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it always refers to some offset of time and space from the norm. For example, in a network transmission, jitter would be a bit arriving either ahead or behind a standard clock cycle Performance of the Si53xx Makes it Ideal for High-Performance Applications
AUSTIN, Texas -- Silicon Laboratories Inc. (Nasdaq:SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, today announced the industry's first jitter-attenuating clock multiplier IC that generates any output frequency from any input frequency with 0.3 picosecond jitter performance. The Si53xx Any-Rate Precision Clocks product family features nine devices leveraging Silicon Laboratories' proven DSPLL([R]) technology to offer the industry's broadest portfolio of reconfigurable, frequency-agile precision clock sources. The Si53xx any-rate capability addresses a wide range of high-performance applications including next-generation networking, telecommunications, wireless base stations, test and measurement, HDTV (High Definition TV) A set of digital television (DTV) standards that offer the highest resolution and sharpest picture. Although some HDTV sets are available in standard (rather square) screen sizes, the overwhelming majority of sets are wide screen, which eliminates video and high-speed data acquisition.
The high-performance Si53xx is the first clock multiplier to generate any output frequency from 2 kHz to 945 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. and select frequencies to 1.4 GHz from any input frequency between 2 kHz and 710 MHz. The ultra-low jitter generation of the Si53xx rivals traditional analog PLLs built discretely using expensive voltage-controlled crystal oscillators (VCXOs) or voltage-controlled SAW oscillators (VCSOs). The Si53xx family features an integrated loop filter with selectable bandwidths, allowing designers to change the loop bandwidth without changing components and enabling jitter performance optimization at the application level.
The Si53xx integrates a rich set of features on-chip, reducing the bill-of-materials (BOM) while optimizing jitter performance. The Si53xx includes an ultra-low phase noise, frequency-agile voltage-controlled oscillator A voltage-controlled oscillator or VCO is an electronic oscillator designed to be controlled in oscillation frequency by a voltage input. The frequency of oscillation is varied by the applied DC voltage, while modulating signals may also be fed into the VCO to cause (VCO (1) (Voltage Controlled Oscillator) An oscillator that can be tuned over a wide range of frequencies by applying a voltage (tuning voltage) to it. Used in many applications such as radio tuners, VCOs are less costly than crystal oscillators, but not as stable. ), loop filter, phase detector A phase detector is a frequency mixer or analog multiplier circuit that generates a voltage signal which represents the difference in phase between two signal inputs. It is an essential element of the phase-locked loop (PLL). , divider divider

By eliminating the noise entry points, the Si53xx simplifies the task of achieving ultra-low jitter performance. Additionally, the Si53xx family supports up to four clock inputs and five differential clock outputs, eliminating the need for external muxes and clock distribution buffers traditionally used in complex timing subsystems of modern communications equipment.
The Si53xx family simplifies the design and supply chain issues of modern timing architectures. Unlike traditional PLL implementations that only operate over a limited frequency range, the Si53xx family can be digitally reconfigured to operate over a broad range of frequencies, removing the need for multiple expensive VCXOs or VCSOs and easing design reuse. The Si53xx family also supports hitless switching to absorb phase differences between input clocks during a clock switchover switch·o·ver

"The any-rate capability of the Si53xx family broadens the addressable Reachable. When something is addressable, it can be identified and manipulated independently of its surroundings. For example, screen pixels and RAM memory are addressable. Each of the screen's picture elements can be individually turned on and off, and each of the memory's bytes can be market of our timing solutions," said David Bresemann, vice president of Silicon Laboratories.

A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air and voltage controlled oscillator products creates the industry's most comprehensive portfolio of frequency-flexible, low-jitter timing solutions."
