The recommended power-up sequence is to apply VCC first, followed by VDD. This ensures that the internal voltage regulators are powered up correctly.
To ensure a stable state during power-up, it is recommended to add a 1uF capacitor between the VCC pin and GND, and a 10nF capacitor between the VDD pin and GND.
The maximum frequency deviation allowed for the LTC6904 is ±50ppm. This ensures that the device operates within its specified frequency range.
While the LTC6904 is specified for 3.3V or 5V operation, it can be used with other voltage supplies within the recommended operating range of 2.7V to 5.5V. However, the device's performance and accuracy may be affected.
To synchronize multiple LTC6904 devices, connect the SYNC pin of each device together and drive them with a common clock signal. This ensures that all devices are synchronized to the same clock frequency.
