“The ZL30153 and ZL30154 are flexible and highly integrated SyncE solutions,” 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 accelerate the development of multiple communications solutions.”
The new 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 one hertz (Hz) to 750 megahertz (MHz) allowing 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 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 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.
