Silicon Laboratories Si53xx Family of Clock Multipliers

QUICK TAKE:
Emerging as an industry first, the Si53xx family of jitter-attenuating clock multipliers generate any output frequency from any input frequency with 0.3 ps jitter performance. (See figure) SILICON LABORATORIES INC., Austin, TX. (877) 444-3032.

MORE INFO:
Employing the company's third-generation DSPLL technology, the family consists of nine devices that can generate any output frequency from 2 kHz to 945 MHz and select frequencies to 1.4 GHz from any input frequency between 2 kHz and 710 Applications include networking, telecom, wireless base stations, test and measurement, HDTV, and data acquisition. The devices feature an integrated loop filter with selectable bandwidths, allowing users to change loop bandwidth without altering components. Other features include a voltage-controlled oscillator, phase detector, divider, and buffers. EEPN At Your Service www.eepn.com/service

WHY IS THIS IMPORTANT?
Traditional PLL designs require discrete components, creating noise entry points between circuit elements. 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.

MORE ABOUT DSPLL
Silicon Laboratories invented the DSPLL approach to simplify the clock multiplication and jitter attenuation circuitry required in high-speed telecommunication applications. This technology replaces multiple discrete phase-locked-loop (PLL) components with a single IC that integrates digital signal processing (DSP) circuitry and an ultra-low jitter, voltage-controlled oscillator.

PRICE & AVAILABILITY
The Si53xx family consists of four any-rate multipliers, the Si5322, Si5325, Si5365, and the Si5367, and five any-rate clock multipliers/jitter attenuators, the Si5316, Si5323, Si5326, Si 5366, and Si5368. Available now, prices range from $12.10 to $72.45 each/1,000.
