SyncE timing devices first to support Telecom, Ethernet and OTN clock rates
Microsemi has unveiled the world's first SyncE timing devices to support Telecom, Ethernet and OTN clock rates.
According to the semiconductor specialist, the single chip, standards compliant Synchronous Ethernet (SyncE) solutions allow the transmission of SyncE over Optical Transport Network (OTN) channels without the need for additional rate conversion phased locked loops (PLLs).
The ZL30153 and ZL30154 SyncE timing devices support flexible input and output rates, whereas Microsemi's previous generation SyncE solutions only support Telecom and Ethernet clock rates. The programmable digital PLLs in both devices synchronise to any clock rate from 1Hz to 750MHz. This allows the 1p/s GPS signal to be used directly as an input reference. In addition, the programmable synthesisers generate any clock rate from 1Hz to 750MHz.
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 synchronisation. According to Microsemi, the devices deliver high performance at a considerably lower cost than others on the market and require an inexpensive temperature controlled crystal oscillator (TCXO) to achieve full compliance with ITU-T Recommendation G.8262.
"The ZL30153 and ZL30154 are the most flexible and highly integrated SyncE solutions available in the market today, and indicative of the industry leading products we plan to develop moving forward," said Russ Garcia, Microsemi evp and general manager of the company's Communications and Medical Products group. "We are committed to making the investments required to further strengthen our leadership position in timing products, and accelerate the development of multiple communications solutions that set the standard for performance and reliability."
