Microsemi Corporation ZL30155GGG2

Description
The Microsemi ZL30155 is a dualchannel universal clock translator that provides programmable clock generation and translation for highspeed networking applications. It features two independent clock channels, each with a programmable synthesizer that can generate any clock rate from 1 kHz to 750 MHz. The ZL30155 also includes two precision synthesizers that generate clocks with jitter below 0.7 ps RMS for 10G PHYs.

Features
Two independent clock channels
Programmable synthesizers generate any clock rate from 1 kHz to 750 MHz
Two precision synthesizers generate clocks with jitter below 0.7 ps RMS for 10G PHYs
Programmable digital PLLs synchronize to any clock rate from 1 kHz to 750 MHz
Flexible twostage architecture translates between arbitrary data, line coding, and FEC rates
Digital PLLs filter jitter from 14 Hz, 28 Hz, 56 Hz, 112 Hz, 224 Hz, 448 Hz, or 896 Hz
Automatic hitless reference switching and digital holdover on reference fail
Four reference inputs configurable as singleended or differential
Customerdefined default device configuration, including input/output frequencies, is available via OTP (One Time Programmable) memory
Dynamically configurable via SPI/I2C interface and volatile configuration registers

Applications
10 Gigabit line cards
Synchronous Ethernet, 10 GBASER, and 10 GBASEW
OTN multiplexers and transponders
SONET/SDH, Fibre Channel, XAUI
