The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.
-
The analog input impedance of the PCM3006T is dependent on the gain setting. For optimal performance, use a source impedance of 1 kΩ or less for gains of 0 dB to 20 dB, and 100 Ω or less for gains above 20 dB.
-
The maximum clock frequency for the PCM3006T is 50 MHz. However, the actual clock frequency used may be limited by the specific application and system requirements.
-
To minimize the effects of clock jitter and phase noise, use a high-quality clock source with low jitter and phase noise. Additionally, use a clock buffer or jitter attenuator if necessary, and ensure that the clock signal is properly terminated and filtered.
-
To minimize noise and interference, use a multi-layer PCB with separate analog and digital grounds. Keep the analog input traces short and away from digital signals, and use a star-configuration for the power supply connections.
