DESCRIPTION
FINAL FEATURES
DATASHEET ACS8526 LC/P LITE The ACS8526 has two SEC reference clock input ports, configured for expected frequency by setting hardware pins or by writing to registers via the serial interface. The ACS8526 can perform frequency translation, converting, for example, an 8 kHz SEC input clock from a backplane into a 155.52 MHz clock for local line cards. The ACS8526 generates two independent SEC clock outputs, one on a PECL/LVDS port and one on a TTL/CMOS port, at spot frequencies configured by hardware pins, or by writing to registers via the serial interface. The hardware selectable spot frequencies range from 1.544 MHz up to 155.52 MHz, with further options for N x E1/DS1 and 311.04 MHz via register selection. The ACS8526 also provides an 8 kHz Frame Sync output and 2 kHz Multi-Frame Sync output, both with programmable pulse width and polarity. Advanced configuration possibilities are available via the serial port (which can be SPI compatible), however the bas...
