World's First SyncE Timing Devices to Support Telecom, Ethernet and OTN Clock Rates

Date: 19/1/2012

Microsemi Corporation has released the world's first single-chip, standards-compliant Synchronous Ethernet (SyncE) solutions, enabling the transmission of SyncE over Optical Transport Network (OTN) channels without the need for additional rate conversion phased locked loops (PLLs).

The most flexible and highly integrated fully SyncE compliant solutions currently available, the new ZL30153 and ZL30154 timing devices support Ethernet clock rates, all OTN clock rates and flexible input, output rates. The programmable digital PLLs in both devices synchronize to any clock rate from one hertz (Hz) to 750 megahertz (MHz), enabling the use of one-pulse-per-second global positioning system (GPS) signal to be used directly as an input reference. In addition, the programmable synthesizers generate any clock rate from one Hz to 750 MHz.

The ZL30154 timing card device provides two independent digital PLLs for applications that require independent transmit and receive timing paths, while the ZL30153 device uses a single digital PLL for clock synchronization. Delivering high performance at a considerably lower cost, the new devices require only an inexpensive temperature controlled crystal oscillator (TCXO) to achieve full compliance with ITU-T Recommendation G.8262.

According to Ercument Yagmur, who heads Ismosys’ operation in Turkey, the new Microsemi single-chip solutions for both SyncE and OTN applications allow telecom equipment manufacturers to support multiple services over a single network and lower timing solutions costs: “Currently available solutions only support Telecom and Ethernet clock rates”, Yagmur said. “The ZL30153 and ZL30154 are a shining example of Microsemi’s commitment to develop multiple communications solutions that set the standard for performance and reliability.”
