P_Down/RST

Power down; When high, requires the module to limit power

consumption to 1.5W or below. 2-Wire serial interface must

be functional in the low power mode.

Reset; The falling edge initiates a complete reset of the

module including the2-wire serial interface, equivalent to a

power cycle.

Notes:

1.

Module ground pins GND are isolated from the module case and chassis ground within the module.

2.

Shall be pulled up with 4.7K-10Kohms to a voltage between 3.15V and 3.45V on the host board.

3.

The pins are open within module.

4.

Reference Clock is not required
