PhaseLink Corporation Announces the Availability of Complete Line of Fanout and Zero-Delay Buffers
1.8V~3.3V Operation, 10 - 220 MHz, 32KHz Buffers, Low Power, Low Jitter, Low Skew
Fremont, California - December 15, 2008. PhaseLink Corporation, a leader in frequency source generation and the inventor of the Analog Frequency Multiplier, PhasorV, and PicoPLL, today announced the availability of the PL123 family of buffers, the newest addition to PhaseLink's growing portfolio of clock and timing solutions. These new ICs support a wide range of end markets requiring high-speed and low-jitter clock distribution, including servers, switches, routers, set-top boxes, flat-panel displays, memory, and computing applications.
PhaseLink's new PL123 line of PLL and non-PLL based buffers includes devices unique to
PhaseLink, as well as multi-sourced industry-standard devices. The unique PhaseLink products take
advantage of PhaseLink's competencies in lowest power consumption and smallest footprint to
extend support for power supplies from 3.3V down to 1.8V, operate from DC to 220 MHz, and feature
the lowest power, package size, jitter, and output-to-output skew in the industry. The multi-sourced
products complete the portfolio, and feature the lowest-power available anywhere. Altogether, the
PL123 family provides new options for current and next-generation designs, and is competitively
priced for market adoption.
"The addition of these nine new products demonstrates PhaseLink's commitment as a broad-based supplier of timing solutions for a variety of end markets," said Amir Naghavi, Vice President of Marketing. "With several new products offering improved performance while maintaining backward compatibility with existing sources, designers have more options for solving their most demanding clocking requirements."
Product Family Summary
PhaseLink's PL123 family of buffers includes general-purpose ZDBs and fan-out buffers (PL123), as well as spread-compatible ZDBs (PL123S), and enhanced-performance ZDBs (PL123E), all fitting industry-standard PCB footprints.
Zero-delay buffers (ZDBs) are fan-out buffers without the penalty of propagation delay. Used mainly for clock distribution applications, ZDBs provide the option of advancing or delaying the output clocks with respect to the input clock, based on the output loading used.
Spread-spectrum modulation clocking is often used to reduce electromagnetic interference (EMI) effects, popularly used in consumer applications to pass strict FCC regulations. Spread-compatible ZDBs have sufficiently high bandwidth to pass spread-spectrum input clocks. Distributing spreadspectrum clocks without using a spread-compatible ZDB may remove desired clock harmonics, resulting in system timing and synchronization problems.
