Single-chip line card device integrates dual DPLLs and NCOs

March 13, 2012 // By Paul Buckley
Microsemi Corporation has expanded the industry's largest synchronous Ethernet (SynchE) product portfolio with the single-chip, ZL30150 line card device for mobile multimedia and packet-based carrier Ethernet applications. Microsemi’s ZL30150 features two integrated digital phase lock loops (DPLLs) that can lock on to up to four inputs for applications that require independent transmit and receive timing paths.

The new line card device also integrates two numerically controlled oscillators (NCOs) ideally suited to network measurement and control systems used in GSM, WCDMA and LTE applications. Three large telecom equipment manufacturers have already selected ZL30150 for next-generation routers and switches.

The ZL30150 supports the Synchronous Optical Ethernet ports for 10GBASE-W and 10GBASE-R requiring multiple frequency translation paths to synchronize the optical port with the system backplane and to translate the receive line clock rate to the system backplane clock rate for use in system synchronization.

Availability and Support

The ZL30150 is available in volume production quantities now. Additional information on Microsemi’s Synchronous Ethernet timing devices, including full data sheets and application notes, is available to qualified customers.
