Singlechipclockmultiplier
The AV9170-07 is a PLL (Phase-Locked Loop) based
frequency multiplier designed for use on Media Vision sound
boards. This clock output is 4X the input clock, it is restricted
to the output divider and the VCO range. The output frequency
rangeis1to12.5MHz, withaninputrangeof0.64to0.768MHz
for IN and 0.256 to 3.072MHz for FBIN. By integrating the
sensitive analog sections of the PLL, such as the phase
comparator, loopfilterandVCO, jitterisminimizedandexternal
part count is reduced.
