NOTE: MCLK: 2.048 MHz, 4.096 MHz or 8.192 MHz with tolerance of ± 50 ppm

NOTE: Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause

permanent damage to the device. This is a stress rating only and functional operation of the

device at these or any other conditions above those indicated in the operational sections of

this specification is not implied. Exposure to absolute maximum rating conditions for extended

periods may affect reliability.
