Semtech extends network timing platform with single-chip solution
The ACS9522T claims to break new ground in the industry by providing a complete single-chip hardware and software synchronization solution for IP-based wireline and wireless applications, with a special emphasis on the requirements of the emerging 4G LTE and small cell market.
The ACS9522T integrates a CPU, memory and six phase-lock loops (PLLs) needed to support IEEE 1588 packet-based synchronization as well as frequency synchronization via synchronous Ethernet or SONET/SDH. This closely coupled architecture delivers the industry’s best time alignment performance by offering advanced features such as synchronous Ethernet / IEEE 1588 hybrid mode operation and network asymmetry correction.
The device also supports different system synchronization architectures without loss of flexibility. The new multi-PLL architecture allows seamless integration of multiple local and network timing sources for enhanced system availability.
The device features a brand new GUI for rapid system configuration and prototyping, enabling an almost push-button process to convert the configuration into production system software. This is designed to significantly reduce costly reconfiguration and testing cycles and speed up time to market.
The ACS9522T ToPSync solution offers complete single-chip sync solution – packet and physical layer timing. The device fully supports IEEE1588-2008 master, slave and boundary clock operation.
Offering industry-leading IEEE1588 performance through the use of Semtech’s patented clock recovery techniques with better than 300 ns phase alignment with ITU-T G.8261 10-switch test network. The device’s synchronous Ethernet / IEEE1588 hybrid mode improves performance to sub-100 ns.
The ACS9522T features dual physical-layer PLLs and dual packet-timing PLLs to support multiple clock sources with Dual Packet Timing PLLs for multiple PTP flows. The ACS9522T is fully compliant with ITU-T G.8265 ‘telecom profile’.
Availability and Pricing
The ACS9522T product is available immediately in production quantities and is priced at $35.00 each in 10,000-piece lots.
