Not Recommended for New Designs. Please contact your local Semtech sales representative.

Features


  • Partner to the ACS8520 & ACS8530 for use in SONET Minimum Clock (SMC) or SONET/SDH Equipment Clock (SEC) applications, to provide :
  • One Extra independent T4 path for those systems being designed to Figure 5-21 of Bellcore GR253[17],
  • An additional DPLL for accurate phase, average phase, frequency and average frequency measuring of any clock source.
  • Phase measurement accuracy to 0.7 degrees.
  • Frequency measurement accuracy to 3x10(-10)
  • Aids in enhancing Phase Build-out performance to absorb phase disturbances when switching between noisy input sources, via s/w control.
  • Provides the facility to have long term frequency measuring and averaging for BOTH the main and any standby clock source so that the holdover frequency is always accurate for both main and standby clock selections.
  • Accepts 14 individual input reference clocks, all with robust input clock source quality monitoring.
  • Microprocessor interface - Intel, Motorola, Serial, Multiplexed, or boot from EPROM
  • IEEE 1149.1[5] JTAG Boundary Scan
  • Single 3.3 V operation. 5 V tolerant
  • Lead (Pb)-free version available (ACS8514T), RoHS and WEEE compliant
