Microsemi ZL30252
Multiplier and Jitter Attenuator
FEATURES
● Input Clocks● Three inputs: two differential/CMOS, one CMOS
● Any input frequency from 1kHz to 1250MHz (1kHz to 300MHz for CMOS)
● Inputs continually monitored for activity and frequency accuracy
● Automatic or manual reference switching
● Low-Bandwidth DPLL
● Programmable bandwidth, 14Hz to 500Hz
● Attenuates jitter up to several UI
● Freerun or digital hold on loss of all inputs
● Digitally controlled phase adjustment
● Low-Jitter Fractional-N APLL and 3 Outputs
● Any output frequency from <1Hz to 1035MHz
● High-resolution fractional frequency conversion with 0ppm error
● Easy-to-configure, encapsulated design requires no external VCXO or loop filter components
● Each output has independent dividers
● Output jitter is typically 0.16 to 0.28ps RMS (12kHz-20MHz integration band)
● Outputs are CML or 2xCMOS, can interface to LVDS, LVPECL, HSTL, SSTL and HCSL
● In 2xCMOS mode, the P and N pins can be different frequencies (e.g. 125MHz and 25MHz) ZL30252, ZL30253 3-Input, 3-Ou...
