ACS8595中文资料用于SONET / SDH的AdvancedTCA系统ATCA线卡保护开关数据手册Semtech规格书

特性 Features

·SONET/SDH applications up to OC-3/STM-1 bit rates
·Switches between grouped inputs (SEC/Sync pairs)
·Inputs: three SECs at any of 2, 4, 8 kHz (and N x 8 kHz multiples up to 155.52 MHz), plus Frame Sync/Multi-Frame Sync
·Outputs: Six SEC clocks at any of several spot frequencies from 2 kHz up to 77.76 MHz via the TTL/CMOS port and up to 311.04 MHz via the PECL/LVDS port
·Modes for E3/DS3 and multiple E1/DS1 rate output clocks
·Generates 8 kHz Frame Sync and 2 kHz Multi-Frame Sync output clocks with programmable pulse width and polarity
·Frequency translation of SEC input clock to different local line card clocks
·Robust activity monitoring on all clock inputs
·Supports Free-run, Locked and Digital Holdover modes of operation
·Automatic \"Hit-less\" source switchover on loss of input
·External force fast switch between SEC1/SEC2 inputs
·Phase Build-out for output clock phase continuity during input switchover
·PLL “Locked” and “Acquisition” bandwidths individually selectable from 18, 35 or 70 Hz
·Serial interface for device set-up
·IEEE 1149.1 JTAG Boundary Scan is supported.
·Single 3.3 V operation, 5 V I/O compatible
·Operating temperature (ambient) of -40 to +85°C
·Available in 100-pin LQFP package
·Lead (Pb)-free version (ACS8595T), RoHS and WEEE compliant
