ACS8527规格书详情
Description
The ACS8527 is a highly integrated, single-chip, MUX with PLL solution for protection switching between two SECs (SDH/SONET Equipment Clocks) from Master and Slave SETS (Synchronous Equipment Timing Source) clock cards, for line cards in a PDH, SONET or SDH Network Element. The ACS8527 has fast activity monitors on the inputs and will raise a flag on a pin if there is a loss of activity on the currently selected input. The protection switching between the input reference clock sources is controlled by an external pin.
Features
◆ Line card protection switch - partners Semtech SETS devices for Stratum 3E/3/4E/4 PDH, SONET or SDH applications
◆ High performance DPLL/APLL solution
◆ Output jitter compliant to STM-1
◆ Two independent SEC inputs ports (TTL)
◆ Four independent output ports:
◆ Two clock ports: one LVDS, one TTL
◆ Two Syncs (TTL): 8 kHz FrSync & 2 KHz MFrSync
◆ I/O frequencies configurable via hardware pins:
◆ TTL I/O ports: spot frequencies 1.544 MHz to 77.76 MHz
◆ LVDS output port: spot frequencies 19.44 MHz to 155.52 MHz
◆ Digital Holdover mode on input failure
◆ “Loss of activity” on selected input flagged on dedicated pin
◆ Source switch under external hardware control
◆ 7O Hz (acquisition) /35 Hz (locked) DPLL bandwidth
◆ Output clock phase continuity to GR-1244-CORE[13]
◆ Single 3.3 V operation, 5 V I/O compatible
◆ IEEE 1149.1 JTAG Boundary Scan is supported
◆ Operating temperature (ambient) of -40 to +85°C
◆ Available in LQFP 64 package
◆ Lead (Pb)-free version available (ACS8527T). RoHS and WEE compliant
