Multigig debuts single IC dual-PLL programmable synthesizer

Multigig, a provider of high-performance timing ICs for the wired and wireless communications, announces its MPS14, a dual-PLL synthesizer on a single IC for high-speed telecommunications applications.

The MPS14 is designed to offer high performance, ultra low jitter between 0.2ps and 0.45ps, and advanced clocking functions through external FPGA logic. The MPS14 is the first device in the company’s Multigig Precision Synthesizer product family.

Addressing the increased port density needs of Optical Transport Network (OTN), broadcast video, and other telecommunications applications, the MPS14 integrates two ultra-low-jitter flexible PLLs able to independently generate output frequencies from 12MHz to 938MHz with precision better than 0.1ppb. The MPS14 also delivers clocking capabilities that benefit applications in networking, data storage, SERDES, and PHY applications.

The MPS14 operates from a low-cost fundamental mode crystal in the range of 22MHz to 54MHz, features independently programmable output buffers with independent power rails that allow mix-and-match output formats, and supports any combination of LVPECL, LVDS, HCSL, and CMOS on its 4 outputs.

"The MPS14 directly addresses the integration and port density needs of the next generation of telecom infrastructure, while also providing the performance, flexibility, and functionality that the industry requires,” says Michael Canning, CEO of Multigig Inc.

The new offering is based on Multigig's proprietary RotaryWave, and features DigiPull technology that replaces analog varactor-based crystal pulling with precise numerical frequency tuning. It can operate as a configurable jitter attenuator when controlled using an FPGA through an SPI bus. Using the FPGA, a customer can scale inputs and implement special-purpose functions, such as hitless switching, hold over, phase offset control, and fast lock. The MPS14 can also operate as an exact frequency translator or clock generator with ultra low jitter.

The MPS14 7x7mm 48-pin QFN is available now for sampling. Pricing varies based on volume.
