‘Any-rate’ clock multipliers deliver industry-leading low jitter
The new solutions focus on high frequency and ultra-low jitter output clocks with integration of fanout buffers and optional custom configuration. These solutions target applications such as enterprise routers and switches, storage area network (SAN) equipment, servers and communications equipment.
With the increase of data rates and bandwidth demand to support faster access to data, high-speed transceivers are deployed in new systems to meet these requirements. Microsemi’s new clock generator family is ideal for clocking high-speed transceivers, including 10G, 40G and 100G Ethernet, and supporting many interfaces including Fiber Channel, Infiniband, XAUI and PCI Express.
The MAX24405/10 and MAX24505/10 high-performance clock synthesizers and the MAX24605 and MAX24610 high-performance jitter attenuators deliver industry-leading jitter as low as 180 femtoseconds to provide spec-compliant timing for high-performance system components and multi-gigabit interfaces. All variants provide any-to-any frequency conversions for clock signals from 10 MHz to 750 MHz.
“In the last six months, we strengthened our timing and synchronization portfolio with our first family of clock buffers, highly integrated dual- and single-channel clock generators, and now six high-performance multi-frequency clock synthesis solutions,” said Maamoun Seido, vice president and business unit manager of Microsemi’s timing products. “We continue to focus on accelerating product development programs across our timing and synchronization portfolio and aligning our roadmap with industry needs.”
Each product variant integrates two synthesizers and supports two independent frequency families, replacing competing two-chip solutions. The MAX24505 and MAX24510 have on-chip EEPROM for custom configuration allowing designers to easily provide desired clocks immediately after power-up.
Additional features include the ability to generate up to 20 output clock signals in two frequency families with control over each output clock’s signal format, voltage, drive strength, frequency divider and phase, eliminating the need for external support components such as fanout buffers and format converters.
The MAX24605/10 jitter attenuators integrate a low-loop-bandwidth digital phase locked loop (DPLL) to filter low-frequency jitter starting at 4 Hz.
All variants are pin-compatible providing easy migration of clock-tree designs from one platform to another.
Pricing
The six product variants are available in production volumes now starting at $6.50 each in 10,000 unit quantities.
