7 / 20 page AD1984B Rev. 0 | Page 7 of 20 | February 2008 HD–AUDIO LINK SPECIFICATION High definition audio signals comply with the High Definition Audio Specification. Please refer to these specifications at www.intel.com/standards/hdaudio. POWER-DOWN STATES POWER SUPPLY Analog (AVDD) 3.3 V ±5% Power Supply Range Power Dissipation Supply Current 3.13 3.30 75.9 23 3.46 V mW mA Digital (DVDD) 3.3 V ±10% Power Supply Range Power Dissipation Supply Current 2.97 3.30 141.9 43 3.63 V mW mA Digital (DVDD) 1.7 through 1.9 V ±10% Power Supply Range Power Dissipation Supply Current 1.615 1.70 61 36 1.995 V mW mA Digital I/O (DVIO) 3.3 V ±10% Power Supply Range Power Dissipation Supply Current 2.97 3.30 3.3 1 3.63 V mW mA Power Supply Rejection (Reference to fS 100 mV p-p Signal @ 1 kHz) 1 80 dB 1 Guaranteed but not tested.

This disables all microphone bias circuits set to 100% or 50%, setting them to the high-Z state. The 0 V and high-Z states remain unaffected by the MIC_BIAS power state. 4.5 4.5 0 0 0 6 6 0 0 0 5 3 2 1 0.1 mA mA mA mA mA |
