SONET/SDH LINE CARD SYNCHRONIZER ZL30117/22
●Zarlink's ZL30117 and ZL30122 chips are the industry’s smallest, lowest power programmable analog/digital PLLs that solve the timing challenges posed by the popular AdvancedTCA (telecommunications computing architecture), AMC (advanced mezzanine card) and MicroTCA architectures.
●Highly integrated devices, the ZL30117/22 PLLs combine the hitless ref-erence switching capabilities of a digital PLL with the jitter performance of an analog PLL. The ZL30117 and ZL30122 are pin compatible and software compatible devices differentiated by jitter performance. With ultra-low jitter performance of less than 1ps, the ZL30117 can be used in applications up to OC-192/STM-64. The ZL30122 limits jitter to less than 3ps and can be used for applications up to OC-12/STM-16. The ZL30117/22 devices accept three reference inputs, supporting clock frequencies in any multiple of 8 kHz up to 77.76 MHz, as well as support-ing 2 kHz. The ZL30117/22 can directly lock to any of the three standard clock inputs available to an AMC in an ATCA or MicroTCA application. The holdover capability of the ZL30117/22 chips also enables them to ride out a complete loss of an incoming reference, which can occur when switching from a failed clock unit to a backup clock unit. The ZL30117/22 PLLs continue to operate in full compliance with network requirements for several seconds after losing their reference, allowing time for the sys-tem to switch to another reference source.
●Simplifying design, the device synthesizes SONET/SDH interface clocks, tributary clock families and SBI or Telecom busses without requiring significant board space or the use of multiple PLLs.
