Microchip Technology, Inc. 2-Ch Line Card Synchronizer ZL30157

The ZL30157 Dual Channel Universal Clock Translator, part of Microsemi's ClockCenter platform of Synchronous Clock devices, delivers industry leading synchronization performance for high-speed complex applications. The highly integrated and programmable solution provides translation from any input reference frequency to any output clock frequency and allows designers to replace multiple components with a single chip, simplifying design and reducing component count and power. The ZL30157 integrates 2 independent digital PLLs, accepts 4 input references and generates 12 programmable clock outputs. One precision synthesizers generates clocks with jitter performance that can directly drive 10 G PHY devices. One general purpose synthesizers generates a wide raneg of digital bus clocks. Additional Features Two independent clock channels Programmable synthesizers generate any clock-rate from 1 kHz to 720 MHz One precision synthesizers generate clocks with jitter below 0.7 ps RMS for 10 G PHYs One general purpose synthesizers generate a wide range of digital bus clocks Programmable digital PLLs synchronize to any clock rate from 1 kHz to 720 MHz Flexible two-stage architecture translates between arbitrary data rates, line coding rates 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 single ended or differential Eight LVPECL outputs and four LVCMOS outputs Eight outputs configurable as LVCMOS or LVDS/LVPECL/HCSL Operates from a single crystal resonator or clock oscillator Customer defined default configuration, including input/output frequencies, is available via OTP (One Time Programmable) memory Configurable via SPI/I2C interface Applications/Uses - 10 Gigabit linecards - Synchronous Ethernet, 10GBASE-R and 10GBASE-W - OTN multiplexers and transponders - SONET/SDH, Fibre Channel, XAUI
