First single chip for Synchronous Ethernet over Optical Transport Networks
The 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 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.
They both support flexible input and output rates and are fully compliant to SyncE standards for telecom and Ethernet clock rates. The programmable digital PLLs in both devices synchronize to any clock rate from 1Hz to 750MHz. This allows the one pulse per second (PPS) global positioning system (GPS) signal to be used directly as an input reference.
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.
