AV9170-07
Clock Multiplier
General Description
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
range is 1 to 12.5MHz, with an input range of 0.64 to 0.768MHz
for IN and 0.256 to 3.072MHz for FBIN. By integrating the
sensitive analog sections of the PLL, such as the phase
comparator, loop filter and VCO, jitter is minimized and external
part count is reduced.
The
AV9170-07
is a derivative of the AV9170 available from
Integrated Circuit Systems, Inc. For additional information

AV9170-07,

Note.
