DESCRIPTION
The PLL601-26 is a low cost integrated XO IC
designed to work with a fundamental 27MHz crystal
or a clock input. In addition to a 27MHz clock
reference output, it provides two selectable audio
frequencies (12.288MHz, and 24.576MHz), making
the chip ideal for handheld, STB and MPEG Video
applications. Additional system frequencies can also
be supported by cascading the PLL601-26 with
PhaseLink's QTC programmable clock family.
PACKAGE PIN CONFIGURATION
Note: ^: Internal pull-up resistor. The internal pull-up resistor
results in a default high value when no pull-down resistor is
connected to this pin.
