World’s first SyncE timing devices support telecom, Ethernet and OTN clock rates

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

The new ZL30153 and ZL30154 timing devices support Ethernet clock rates and all OTN clock rates. Using Microsemi’s single-chip solutions for both SyncE and OTN applications allows telecom equipment manufacturers to support multiple services over a single network and lower timing solutions costs.     

The new ZL30153 and ZL30154 SyncE timing devices support flexible input and output rates and are fully compliant to SyncE standards. Microsemi’s previous generation SyncE solutions, as well as currently available competitive solutions, only support Telecom and Ethernet clock rates. The programmable digital PLLs in both devices synchronize to any clock rate from 1 Hz to 750 MHz). This allows the one pulse per second (PPS) global positioning system (GPS) signal to be used directly as an input reference. In addition, the programmable synthesizers generate any clock rate from 1 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 versus the competition, the new devices require only an inexpensive temperature controlled crystal oscillator (TCXO) to achieve full compliance with ITU-T Recommendation G.8262.
