ZL30721 Product Brief
4
Microsemi Corporation
Input-to-output alignment with external feedback
Up to eight general-purpose I/O pins each with many possible status and control options
Output frame sync signals: 2kHz or 8kHz (SONET/SDH), 1Hz (IEEE 1588) or other frequency
Internal compensation for local oscillator frequency error
2.8 API Software
Interfaces to 1588-capable PHYs and switches with integrated timestamping
Abstraction layer for independence from OS and CPU, from embedded SoC to home-grown
Fits into centralized, highly integrated “pizza box” architectures as well as distributed architectures with
multiple line cards and timing cards
3. Applications
ITU-T G.8262 system timing cards for Synchronous Ethernet systems
System timing cards which support ITU-T G.781 SETS (SDH Equipment Timing Source)
Integrated basestation reference synchronization for air interfaces for
o GSM, WCDMA, TD-SCDMA, LTE and LTE-A
o FDD or TDD mobile technology
o Femtocells, small cells (residential, urban, rural, enterprise), picocells and macrocells
Mobile Backhaul NID, cell-site router, edge switch/router, microwave or access aggregation node
EPON/GPON OLT and ONU/ONT
DSLAM and RT-DSLAM
10G, 40G and 100G line cards
SONET/SDH, Fibre Channel, XAUI
