results in a default high value when no pull-down resistor is

connected to this pin.

DESCRIPTION

The ABMX0127 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, it provides the most common audio clocks

(8.192, 11.2896, 12.288, and 24.576MHz) required by

sampling rates of 32kHz, 44.1kHz, 48kHz, 64kHz and

96kHz, making the chip ideal for STB and MPEG

Video applications.
