DESCRIPTION
The PLL601-22 is a low cost integrated XO IC with
power down feature, designed to work with a
fundamental 27MHz crystal to provide the most
common audio clocks (8.192, 11.2896, 12.288,
16.9344, 16.384, 18.432, 22.5792, and 24.576MHz)
required by sampling rates of 32kHz, 44.1kHz, 48kHz,
64kHz and 96kHz (256, 384 and 512 oversampling
ratios). The wide range of audio frequencies makes it
ideal for STB and MPEG Video applications.
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.
