PLL FUNCTIONAL DESCRIPTION

The device is controlled via the I2C-bus or the 3-wire bus,

depending on the voltage applied on the SW input.

A HIGH-level on the SW input enables the 3-wire bus;

CE/AS, DA and CL inputs are used as enable (CE), data

and clock inputs respectively. A LOW-level on SW input

enables the I2C-bus; the CE/AS, DA and CL inputs are

used as address selection (AS), SDA and SCL input

respectively (see Table 2).
