Typical Applications (continued)

11.2.1.4 Preventing False Output Frequencies in SPI/I2C Mode at Startup:

Some systems require a custom configuration and cannot tolerate any output to start up with a wrong frequency.

Holding RESET low at power-up until the device is fully configured keeps all outputs disabled. The device

calibrates automatically after RESET becomes released and starts out with the desired output frequency.

NOTE

The RESETN pin cannot be held low during I2C communication. Instead, use the SYNC

pin to disable the outputs during an I2C write operation, and toggle RESETN pin

afterwards. Alternatively, other options exist such as using the RESETN bit in the register

space to disable outputs until the write operation is complete.

11.2.1.5 Power Down

When the PDN pin = 0, the device enters a complete power down mode with a current consumption of no more

than 1 mA from the entire device.

11.2.1.6 Device Power Up Timing:

Before the device outputs turn on after power up, the device goes through the following initialization routine:
