21 LVTTL-I
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 the 2-wire
serial interface, equivalent to a power cycle.

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. These PINs are open within module.
4. A Reference Clock input is not required. If present, it will be ignored.
