Microsemi Strengthens its Timing Products Leadership with New Any-to-any Frequency Clock Multiplier and Jitter Attenuator Clock Management Products

Delivering Industry-leading 250fs Jitter in an Ultra-small 5x5 mm Footprint, Devices are Ideal for a Variety of Communications Applications

ALISO VIEJO, Calif., Sept. 3, 2014 — (PRNewswire) — Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today announced its new ZL30252 and ZL30253 any-to-any frequency clock multiplier and jitter attenuator integrated circuits (ICs). With best-in-class jitter performance as a clock multiplier (160fs in the 12kHz-20MHz band) and as a jitter attenuator (250fs in the 12kHz-20MHz band) all in an ultra-small 5x5 mm package, these devices target new applications with tough jitter budgets and tight board real estate restrictions.

The new devices provide communication equipment customers with a timing solution that meets industry-leading jitter performance imposed by new 100Gbps PHY devices. According to market research firm Databeans, the clock generation IC market will grow to approximately $1 billion in 2017 from $700 million in 2013.

"Microsemi's new any-to-any frequency clock multiplier and jitter attenuator products complement our comprehensive timing and synchronization solutions, as well as many of our other leading-edge products that are designed for the growing communications market," said Roger Holliday, senior vice president and general manager, Microsemi's communications group. "We are expanding our overall timing product portfolio and system solutions to address many new and leading-edge applications in the growing clock generation IC market."

The ZL30252 and ZL30253 devices also reduce the overall bill of materials (BOM) cost and simplify design with precise frequency conversion from any input frequency 1kHz to 1.25GHz to any output frequency 1Hz to 1.035GHz and jitter attenuation bandwidths from 14Hz to 500Hz. When combined with Microsemi's ZL402xx series fan-out buffers, the new ZL30252 and ZL30253 provide complete timing solutions for complex systems such as wireless base stations, wireless backhaul, wired infrastructure, SONET/ SDH, GE, 10G/40G/100G Ethernet, optical, storage and broadcast video applications.

"The drive by developers for universal physical layer interfaces employing pluggable optics created the need for flexible clock multipliers such as the ZL30252 and ZL30253," said Maamoun Seido, vice president and business unit manager of Microsemi's timing products. "Furthermore, new physical layer SERDES and mappers are driving the need for the superior jitter performance provided by the ZL30252 and ZL30253 to support the higher data rates."

About the ZL30252 and ZL30253
The ZL30252 and ZL30253 have highly configurable output clocks and offer automatic self-configuration at power-up. This supports up to four different configurations easily selected using two device pins.  Key features include:

  • Any-to-any frequency conversion with 0 ppm error (inputs: 1kHz-1.25GHz, outputs: 1Hz-1GHz)
  • Digital PLL with programmable bandwidth from 14Hz to 500Hz
  • Input clock monitoring and automatic or manual input switching
  • Three universal clock inputs connect to any signal format at any voltage and up to three differential outputs or six CMOS outputs
  • Operate as numerically controlled oscillator (NCO)
  • Configurable output signal format and voltage for direct interface without additional components

The ZL30252 and ZL30253 offers NCO mode in which output frequencies can be controlled with very high resolution by system software. This capability allows the devices to replace solutions using large, expensive, fixed-frequency voltage-controlled oscillators (VCXOs) with a small, low-cost and any output clock solution.

The ZL30252 and ZL30253 are also flexible building-blocks that system designers can use in various parts of their design. For example, they can be used as a master clock jitter attenuator and multiplier for other Microsemi timing ICs. This allows customers to reuse previously-qualified TCXOs or OCXOs regardless of frequency or jitter. When deployed on a line card, the ZL30252 or ZL30253 simplify system design and reduce the cost of backplane connectors by accepting low frequency clocks from the backplane and performing rate conversion and jitter attenuation on the line card.

The ZL30252 and ZL30253 are available now. For more information, visit http://www.microsemi.com/products/timing-and-synchronization/frequency-conversion or for questions, contact Email Contact.

Microsemi's Complementary Products
Microsemi's high performance clock buffers complements the latest any-to-any frequency clock multiplier and jitter attenuator devices by providing additional fan-out capability and the industry's best-in-class power supply noise rejection performance. This preserves signal integrity by adding ultra-low jitter and filtering noise from power supplies, resulting in better performance while simplifying engineering board design efforts. The family of buffers supports clock rates of up to 750MHz. It has a flexible I/O structure, inputs are compatible with LVPECL, LVDS, CML, HCSL, LVCMOS, HSTL and SSTL and outputs support LVPECL and LVDS signals.
